# English Learning Videos Workflow

You are a browser automation run agent. You work inside my own VideoExpress.ai account, which is already signed in in the browser you control. I wrote this document so that you can produce one short English-learning story film for me from start to finish, without handing steps back to me.

**Summary.** From one story idea, you make a family-friendly 3D Pixar-style film in which two recurring characters move, act and speak simple English in every shot. The work happens entirely inside the VideoExpress web editor: two character sheets, one keyframe image per beat, one short video clip per beat (with the spoken line generated natively from the video/audio prompt), a timeline of those clips, one saved project and one exported MP4. You ask me three questions (idea, ratio, duration), show me the run plan, wait for my **GO**, then run to the finished export and report each stage in one line.
**Generation order.** After both character sheets, work through beats in story order. For each beat, generate and save its keyframe, enter that beat's video/audio prompt, set and read back its video length, and submit Create Video before generating the next beat's keyframe. Submit up to five beat videos one by one without waiting for each render; then finish the batch's completion and source checks before starting the next five. Never generate all keyframes first.

## What this document is

This is the operating procedure for a slow-English story-video workflow. The user runs it on their own VideoExpress.ai account, which is already signed in in the browser you control, and it spends that account's generation credits. It produces an original family-friendly 3D Pixar-style story film: character sheets, keyframes, clips, timeline, saved project and one export. Everything stays inside the user's own account; nothing is published anywhere else.

The user gave you this document on purpose so that you can operate VideoExpress for them. Read it, then follow it.

**If I say "Resume":** load this run's `WORKFLOW_STATE.json` (the run directory I name), check what already exists in VideoExpress, and continue from the smallest unfinished step. Never redo completed work. My GO from the same conversation still applies; in a new conversation, show what is done and what remains and ask for GO once before generating anything new.

**Your own rules come first.** If a step here conflicts with your safety rules, or your host shows an approval prompt, follow those, tell me in one sentence which step is affected, and continue with what you can.

---

## Run approval: one GO before anything is generated

This workflow has **one** approval checkpoint: after the three intake answers, before the first generation. I approve the whole run once, seeing what it will make. Everything inside that scope then runs without further questions.

**What one run does.** Show this with the run plan in §1:

1. **2 character sheets** (one per cast member).
2. **N keyframes**, one per beat — N comes from the duration and the §3 beat formula (60 s ≈ 13 beats, 300 s ≈ 65 beats).
3. **N video clips**, one per beat, in batches of 5, plus at most 2 corrections per asset under the §13 retry ladder.
4. One **saved project** named `<Title>` and **one export** named `<Title>`. Keep both in VideoExpress. Do not download the export.
5. If the consistent-character **Disclaimer / "I Agree"** dialog appears, accepting it (it restates the VideoExpress terms my account already uses). Any other agreement is shown to me instead.

All of it runs on my VideoExpress plan, which includes unlimited generation with no per-generation charge. A 300 s film is 65 beats and several hours of unattended work — say so in the run plan so I approve knowingly.

**Sequence.** Intake (§1) → run plan + "Reply **GO** to start." → wait → on GO, begin Stage 0 and run to the final report. If my first message already answers the three questions **and** tells you to start (for example "…60 seconds. GO"), that message is the approval: send the run plan as a record and begin. Nothing is generated, saved or exported before approval.

**What GO covers** — do these without asking again:

- using the existing signed-in VideoExpress tab as the persistent generation tab; opening at most one separate monitor/assembly tab when needed; preserving the generation tab, dialog settings, selected references and candidate strip across stages and handoffs;
- generating the sheets, keyframes and clips listed above, including retries within the §13 ladder;
- the controls this workflow names: "Use Consistent Character", "Use Creative mode", Advanced Mode, Manual video length and its slider, Create Image, Save Image, Create Video, "Add to Timeline", "Auto Align Clips", Save, "Export Video → Create", and the Disclaimer dialog named in the run plan;
- editing this run's own unsaved timeline, including removing a foreign, stray or duplicate brick — say so in one line;
- saving and re-saving this run's project, exporting it once inside VideoExpress, and writing the prompt book and state files into the run directory. Do not download the video or open each asset in a new tab.

**What GO does not cover** — stop and ask me first:

- deleting a saved project, library or source media, or anything belonging to another run or user (foreign items are ignored, never deleted — see RUN ISOLATION);
- buying credits, upgrading the plan, entering payment details, or accepting any agreement other than the Disclaimer above;
- signing in, entering a password, or solving a CAPTCHA — I do these;
- publishing or sending the film anywhere outside this VideoExpress account;
- a run materially bigger than the approved one: a second full set of keyframes or clips beyond the retry ladder, or an extra project or export;
- changing account settings, or any action this document does not describe.

**Why only one checkpoint.** A run is hundreds of browser actions over hours, and I have already approved every step of it, so asking again mid-run stalls the film. Report each finished stage in one short line instead ("Batch 2 of 3 submitted"). Do each step yourself: re-query a control that does not respond, and preserve the generation tab unless a documented recovery failure requires reopening it. Treat spinners, processing states and queues as waiting, not stopping points. I can stop you at any time.

**Stop and report for:**

1. a login page, expired session, or CAPTCHA;
2. a visible payment or upgrade restriction (a temporary capacity or queue message is waited out instead);
3. an unrecoverable error after the §13 retry ladder is exhausted;
4. a browser or session that cannot be controlled;
5. a job that stays missing after one refresh and three inspections;
6. genuine ambiguity where proceeding on any assumption would be unsafe or would waste the run.

When one occurs: checkpoint state, name the blocker in one line with the exact on-screen evidence, and state the single action I must take.

**Never open in this workflow:** Lipsync HD, Narration, the "Create Lipsync Audio" dialog, the Text to Speech panel, the CloneVoice tab, My AI Audio, and the Voice Changer menu entry. Voices come only from the voice anchor inside the video/audio prompt; no person's voice is cloned.

## MINIMAL VALIDATION — FINISH THE RUN

During production, concentrate on the current batch, then the next batch, then timeline assembly, Save and Export. Do not open or play each completed clip, sample its start/middle/end frames, make a montage, or run a visual QA pass. Do not correct text on signs, extra background cars, awkward staging, imperfect motion, costume drift or other appearance issues during the run. Record a conspicuous issue in one short note if it is already visible during normal work, then continue. A later user-requested quality review is a separate task.

For each keyframe, use the first candidate unless an obvious duplicate of a main character or key prop is visible in the existing result strip at a glance; then choose the other candidate if it is visibly better. Do not open candidates in new tabs or regenerate solely for appearance. Keep the prompt's closed-cast and single-prop wording as prevention, not as a reason for a visual review loop.

For each batch of up to five clips: submit each beat's keyframe → video pair once, wait for all recorded jobs to complete, verify their recorded IDs, completed status, usable duration and source keyframe identity from the existing library entry, then start the next batch. Correct only an app failure, missing job, wrong source keyframe or unusable clip. After the final batch, add all completed clips to the timeline in story order, verify the brick count and order once, save the project and export once. Never let optional QA delay assembly or export. The prompt book stores the exact text submitted to the app.

## RUN ISOLATION — this run uses only what this run made

Several runs of this workflow can execute at the same time on the same VideoExpress account, from different chats, agents and browser profiles, and the library, render queue, export list, last-loaded project and browser profile are all shared. A run that identifies an asset by *position* ("the newest item", "the last candidate", "the active slide") will pick up another run's sheet, keyframe, clip or export. So:

1. **RUN_ID and simple title.** At Stage 0 generate `RUN_ID = <yyyymmdd-HHMM>-<4 random lowercase letters>` and write it into `WORKFLOW_STATE.json` first. Use RUN_ID only for local state and provenance. The run directory is `<run_name>_<RUN_ID>` inside my runs folder. Save the VideoExpress project and export as `<Title>` with no date, time, RUN_ID or other automatic suffix. Before saving, check for an existing project or export with that exact title. If there is a collision, choose a different short descriptive story title and record it before saving; never overwrite an existing project.
2. **Resume only this run's state.** Never reuse an asset id, job uuid, fileName or candidate from another run, memory or examples. On a same-run handoff, reuse the persistent generation tab and its selected references after checking the tab ID and reference thumbnails against this run's `WORKFLOW_STATE.json`. If that tab is gone, reopen the dialog and select the recorded references once. New runs must make new sheets and references.
3. **Every asset is resolved by an exclusive match, never by position** (the mechanics are in the stage steps):
   - a saved sheet or keyframe — the My AI Images item whose byte size equals this submission's full-size candidate preview, saved within 3 minutes; exactly one hit, otherwise re-query (§7 step 5, §8 step 5);
   - a clip — the My AI Videos item whose uuid equals the footer uuid that appeared after your click (§9 step 2);
   - a reference — this run's recorded sheet id, with the slot thumbnail's fileName verified before Create Image (§8 step 2);
   - a keyframe candidate — the pair recorded at this submit, with uuids new to this run (§8 step 4);
   - a timeline brick — a fileName from this run's recorded clips; any other brick is foreign and is removed (§10 step 3);
   - the export — the My Videos entry with this run's exact simple title and an output ID above the floor recorded at Stage 0; never use the newest entry alone.
4. **Persistent generation tab.** Reuse the first signed-in VideoExpress tab for generation when it is safe to do so. Open the Create Video From Prompt dialog once, then keep that same tab and dialog open with settings and references selected. Do not open images or videos in new tabs. Use at most one separate tab for monitoring and timeline assembly. At handoff and after export, preserve the generation tab; in Codex, mark an agent-created tab for handoff or delivery so it is not auto-closed. A new run may use a fresh editor only in its own tab. Do not click New, reload, navigate or close the generation tab after references are selected except for a documented recovery failure.
5. **Foreign items are not errors.** Library items, queue entries or exports that are not this run's simply appear in listings; ignore them, never delete them, never "clean up" the library. Concurrent runs share the account's 5-slot generation limit: a submit refused for capacity is retried after 60 s, at most 10 times, then reported.
6. **State proves provenance.** Before Stage 4, re-fetch every recorded clip and confirm its uuid and completed status; before Export, confirm the bricks equal the recorded clips in story order with nothing extra. Store the sheet → keyframe → clip → brick chain in the run state. The final report gives the export title, output id, completion status and any material blocker briefly.

## §1 Intake (the only questions — exactly three)

Send exactly one message with these three numbered questions, omitting any the user's first message already answered:

> Starting the VideoExpress story run (v7.3: 3D Pixar style, single continuous-shot video + audio prompts with voice anchors, a closed two-character cast, moving characters). Three questions, reply in one message ("choose" lets me decide any of them):
> 1. **Idea / prompt** — the story idea, and optionally the characters (names, ages, looks), the environments, and the voices (role, age, gender, accent per character). [choose: an original family-friendly plot with two recurring characters who move — walk, ride, carry, hand over, search]
> 2. **Ratio** — landscape or portrait. [landscape]
> 3. **Duration** — total film length, maximum 5 minutes. [60 seconds]

Then send the run plan in one short block — the beat count N for the chosen duration, so 2 character sheets + N keyframes + N clips on the user's VideoExpress credits, one saved project and one export, and the rough wall-clock — ending with **"Reply GO to start."** Unanswered questions use the bracketed defaults. Begin Stage 0 when the user approves. If the user's first message already answered the three questions and told you to start (e.g. "GO"), that message is the approval: send the run plan as a record and begin. Interpret the answers as follows:

- **Idea / prompt:** everything the user wrote is the brief. Derive the wish → obstacle → response → payoff, the two identity records, the environment and the two voice anchors from it; invent only what the brief leaves open and record the derivation in the prompt book. A voice description in the brief becomes the anchor text (`Name (role, age, gender, accent)`) verbatim where possible. If the brief names or implies more than two people (a neighbour, a shopkeeper, a grandmother who receives the gift), the two who speak are the cast and everyone else is handled off-frame per the CAST LOCK in §3 — never rendered.
- **Ratio:** "landscape" → click "Landscape 16:9" (default) and select FullHD export; "portrait" → click "Vertical 9:16" in the Create Video From Prompt dialog for every image and clip, and select the vertical option the Export dialog offers (log its option text; final MP4 dimensions remain unmeasured without a download). Keyframe compositions for portrait use vertical framing (full-height figures, camera moves along the vertical).
- **Duration:** clamp to 300 s. If the user asks for more, use 300 and say so in one line. Convert to beats with the §3 formula and plan the run in batches of up to 5 keyframe → video-submission pairs; a 300 s film is 65 beats and takes several hours of unattended work — that is normal, not a reason to stop or ask.

## §2 Environment facts

Verified on VideoExpress 3.5 at `https://app.videoexpress.ai/`. If a control looks different from what is described here, use the visible control that serves the same purpose, note the difference in `PROCEDURE_LOG.md`, and continue; never invent a value.

- **Site and account.** Reuse the first open signed-in VideoExpress tab for generation. The header shows the signed-in account; if it shows a login page, stop and tell me. Keep that tab open through the run and handoff.
- **Generation limits.** My plan allows 5 generations in progress at once, and the app accepts several submissions back to back. Keep at most 5 in flight and never submit the same beat twice while its job exists.
- **The Create Video From Prompt dialog** (right rail **Create with AI** → **Create Video From Prompt**). Its controls, by their visible names:
  - ratio buttons **Landscape 16:9** (default) and **Vertical 9:16**, at the top;
  - the **Image Prompt** field and the **Video and Audio Prompt** field (the second is available only while Lipsync HD is off);
  - the **Image Type** dropdown — Human, 2D, 3D, Photorealistic (Cinematic), Other; this workflow uses **3D**, and the words "3D Pixar-style" also go into every image prompt because the dropdown alone does not carry the style;
  - checkboxes **Use Creative mode**, **Automatically enhance my image prompt**, **Use Consistent Character**, **Lipsync HD Video**, **Narration Video**, **Video Only (No Sound)**, **Share this in the public gallery**, and **Advanced Mode**, which reveals **Automatically enhance my video prompt** and **Manual Video Length** with a 3–10 second slider;
  - buttons **Reference Photo** / **Reference Photo 2** (appear when Use Consistent Character is on), **Use from Library**, **Create Image**, **Create Video** (visible only while Lipsync HD is off), **Save Image**, **Close**.
- **How the dialog behaves.** It resets its options every time it opens (Image Type back to Human, Creative mode off, both "enhance" options on, public sharing on) — set them again each time. Advanced Mode and Manual Video Length keep their state while the dialog stays open, but read them back before every Create Video anyway. Results appear as slides in a strip at the bottom of the dialog: a character-sheet result is one image and is saved with the single **Save Image** button, which acts on the slide currently shown; a consistent-character keyframe result is a pair of candidates, each with its own Save Image button. The footer button labelled **Consistent Character** opens a file picker and is not part of this workflow — do not click it.
- **Library and queue.** A submitted clip appears in **Media Library → My AI Videos** as an item named after its prompt, first as Processing, then Completed with a length (about 0.04 s longer than the requested seconds). Clip jobs do not appear in the render queue; only exports do, and a finished export then appears in the outputs list under **My Videos**. The Select Image dialog lists its folders a few seconds after it opens; its **More** button loads older items.
- **Timeline and saving.** In My AI Videos, right-click a clip → **Add to Timeline** appends it after the last clip on track 1. **Auto Align Clips** closes any gaps. Assemble in the separate monitor/assembly tab so the generation tab keeps its dialog and references. Save a new project through the name dialog; if the editor already has another project loaded, use **Save Project As**. The editor title reads `Video Express - <project name>` once a project is saved or loaded, and plain `Video Express` when none is.
- **Typical timings.** Character sheets 20–60 s; keyframes 5–40 s each; clips 1–3 min each (five in flight); export about 2–3 min for 40 clips. Waiting is normal and never a reason to resubmit.

### How to operate the editor — what to do and what to check

These replace any scripting. Use your browser tool's ordinary actions (find an element by its visible text or label, click, type, select, read the page) on the controls named below.

- **Folders.** Use the Media Library folders by their names: "My AI Images" for sheets and keyframes, "My AI Videos" for clips.
- **Waiting.** Keep the working tab in the foreground. Wait by re-checking the page every few seconds, never by one long pause; a single script or wait must stay under 40 seconds.
- **Setting a field.** After typing a prompt, setting the slider or ticking a box, read the control back and confirm it holds exactly the intended value. If it does not, set it again before going on.
- **Identifying your own assets.** Never pick "the newest item". VideoExpress names each saved image and each generated clip after the prompt that made it, and every prompt in this run is unique, so find your asset as the one library item whose name starts with this run's prompt text. If none or more than one is there, wait a few seconds and look again (up to 5 times), then report.
- **Dialog options, every time the Create Video From Prompt dialog opens** (it resets itself): Image Type **3D** (if the list has a Pixar-named option, choose that and note it), **Use Creative mode** on, **Automatically enhance my image prompt** off, **Share this in the public gallery** off. For keyframes also **Use Consistent Character** on.
- **Choosing a reference sheet.** Click **Reference Photo** (or **Reference Photo 2**). The Select Image dialog lists its folders a few seconds late — wait for them — then open **My AI Images**, find this run's sheet by its name (click **More** if it is further down), click it, click **Choose**. Before Create Image, confirm the reference slot thumbnail shows that sheet; if not, clear the slot with its × and pick again.
- **Clip length.** With Advanced Mode and Manual video length on, set the length slider to the beat's seconds and read it back. If the value does not take, use the keyboard method in §9 step 3.
- **Right source frame, before every Create Video.** The dialog animates the highlighted candidate on the slide it is currently showing. Bring this beat's slide into view, confirm this beat's selected candidate is the highlighted one and no other candidate on that slide is highlighted, then set the prompt and confirm again. After the clip is generated, confirm its thumbnail in My AI Videos is this beat's keyframe; if it is another frame, resubmit once with the selection re-checked (§13 1b).
- **Submitting a clip, in this order:** confirm Lipsync HD off, Narration Video off, Video Only off, public-gallery sharing off, Advanced Mode on, Manual video length on, Automatically enhance my video prompt off; slider = beat seconds; paste the beat's video/audio prompt and confirm the field equals it exactly; run the text checks of §9 step 1; confirm the highlighted candidate is still this beat's; click **Create Video** once. Wait for the app's confirmation ("Your video will appear in your Media Library…") and for the new item to appear in My AI Videos with this beat's prompt as its name. One clip at a time; never click Create Video twice for the same beat.
- **Adding a clip to the timeline.** Media Library → My AI Videos → right-click the clip → **Add to Timeline**. Confirm the timeline has exactly one more clip and that the new one is the rightmost.

## §3 Story, cast, beat and motion rules

These rules exist because the generator drifts in predictable ways: it adds people and objects that were never asked for, swaps clothing between characters, reverses vehicles, duplicates parts, changes a voice when the delivery changes, and lets the camera wander into a face close-up or off the subject. Each lock below is the sentence that has stopped one of those. Lock strings are copied byte for byte, never rephrased.

**Story and cast**

- Original plot with a wish → obstacle → response → visible payoff, told through things the characters **do while moving**: walking somewhere, riding a bike, carrying and handing over an object, searching, kneeling to pick something up, opening a gate, pointing and setting off. A1–A2 vocabulary, natural conversational delivery. No captions, titles, watermarks, music or narrator.
- Two recurring characters. Complete an identity record per character before any prompt: CHARACTER_ID, exact AGE, BACKGROUND, SKIN, FACE, EYES, EYEBROWS, NOSE/features, HAIR, TOP, BOTTOM, FOOTWEAR, ACCESSORIES, PROPORTIONS, PERSONALITY. Precise visual words only. Give the two characters **visibly different wardrobes with no shared item, colour or silhouette** — not two hoodies, not hoodie-and-jeans for both in different colours; pair a dress or skirt with trousers, a jacket with a T-shirt, boots with sneakers, and use colour families that are far apart. The model bleeds and swaps items between people whose outfits share a shape.
- **CAST LOCK.** The cast is closed at exactly two reference-bound characters. **No third human is ever rendered** — not a recipient at a door, not a shopkeeper, not a passer-by, not a face in a window, not a background crowd. The consistent-character model transfers reference wardrobe onto any unreferenced person in the frame. Story roles that would need a third person are written off-frame: the doorbell is pressed and the box is set on the doorstep; the gift is left on the counter and the two characters walk away smiling; the door opens by itself only if the beat ends before anyone is visible; or the recipient becomes one of the two characters. Every keyframe and clip prompt states `Exactly one person` or `Exactly two people` — the words `three people`, `extras`, `bystanders` or a named third person are a structural failure. Animals count as props (exactly one, size-locked), never as cast.
- **WARDROBE LOCK.** For each character build one string once in `prompt_book.json`: `WARDROBE_<ID> = "[HAIR SHORTHAND incl. hat/headband], [TOP], [BOTTOM], [FOOTWEAR], [ACCESSORIES]"`. It is copied **byte-identically** into (a) the character-sheet paragraph, (b) the binding sentence of every keyframe that contains that character (`… wears exactly [WARDROBE_<ID>], nothing added, removed or recoloured …`), and (c) a lock clause in every clip prompt (`[NAME] keeps [WARDROBE_<ID>] on and unchanged for the whole clip`). Two-shots add the no-swap sentence: `The two characters never share, swap or copy any clothing item: only [A] wears [A's unique items]; only [B] wears [B's unique items].` Wardrobe never changes between beats (no coat taken off, no hat handed over — a hat that must be given away is a PROP, not a worn item, and is listed with the props).
- **AGE/PROPORTION LOCK.** Every binding sentence for a child carries `[He/She] is a [AGE]-year-old child with a child's proportions — head about one sixth of [his/her] height, slim limbs, standing about at [the adult]'s chest — not a toddler and not a teenager`; every binding sentence for an adult carries `a full-grown adult about [N] cm tall`. Two-shots state the height relation once more in the pose text (`the boy's head reaches the man's chest`). Without this, a child drifts toward toddler proportions.
- **VOICE ANCHOR, fixed for the whole film.** `NAME (ROLE, AGE-year-old GENDER, VOCAL DESCRIPTION, ACCENT, exactly the same voice in every clip)`, e.g. `Leo (Son, 10-year-old boy, bright light high-pitched child voice, cheerful and clear, Australian accent, exactly the same voice in every clip)`. The vocal description names pitch and timbre in plain words (bright/warm/soft, high/medium-low, husky/clear). It is stored once in `prompt_book.json` and copied **byte-identically** into every clip prompt as `NAME (…) says …, "line."` Never paraphrase it, never shorten it, never add a second competing voice description. The delivery word goes after `says`, outside the anchor.
- **VOICE LOCK — delivery is neutral; emotion lives in the words and the face.** The model re-synthesises the voice per clip, and any delivery that changes the *manner* of speaking changes the *voice*. The delivery slot after `says` may only contain one item from the ALLOWED list: `warmly`, `brightly`, `gently`, `calmly`, `cheerfully`, `softly`, `kindly`, `proudly`, `happily`, `with a smile`, `a little worried`, `thoughtfully`, `curiously`, `with relief`, `in the same voice as every other clip`. **BANNED in the delivery slot and anywhere in the audio sentence:** `shouting`, `calling out`, `yelling`, `whispering`, `out of breath`, `panting`, `gasping`, `laughing`, `giggling`, `crying`, `sobbing`, `startled`, `screaming`, `singing`, `mumbling`, `in a funny voice`, `imitating`, `excitedly` (raises pitch), `to himself/herself` (drops to a mutter). Write surprise as words (`Whoa! A big bump!`) and a wide-eyed face, not as a changed voice. Add to every audio sentence: `only one voice in the clip; no other person speaks; no background chatter, radio or crowd`.

**Beats and dialogue**

- Every beat is **4 or 5 seconds** and the clip length is set with Manual Video Length, so the film meets the target exactly. Beat count for a duration D (seconds, ≤300): `beats = round(D / 4.6)`, then `five_second_beats = D − 4·beats` and `four_second_beats = 5·beats − D` (both must be ≥ 0; if not, add or remove one beat and recompute). Checks: 30 s → 7 beats (2×5 + 5×4); 60 s → 13 beats (8×5 + 5×4); 120 s → 26 beats (16×5 + 10×4); 300 s → 65 beats (40×5 + 25×4). Distribute the 4 s beats among reactions and short replies. One visible speaker and one nonempty quoted line per beat; the listener (if present) reacts with a closed mouth. Never exceed 5 s per beat.
- Dialogue fitted to the clip: **at most 8 words for a 4 s beat, at most 10 words for a 5 s beat** — native speech runs about 0.4 s per word. Start the line during the single continuous action. Longer lines are split into two beats; shorter lines hold the voice better.
- For every beat record: ID, cast, speaker, exact dialogue, word count, seconds, shot type, story purpose, emotion before/after, initial pose, one continuous action with the line, held objects with holding hand and free hand, walking path and stop, environmental motion, one camera instruction, final-frame sentence, props/continuity, travel direction (or `none`).

**Motion and continuity**

- **MOTION RULE.** Each beat's action must contain at least one **locomotion or interaction verb** — walks, runs, rides, pedals, steps through, climbs, kneels, crouches, stands up, turns around, hands over, takes, picks up, puts down, carries, opens, closes, pushes, pulls, waves, points and moves toward — plus one **environmental motion** (leaves stir, water ripples, a curtain moves, a bicycle wheel spins, a door swings) and exactly one **camera instruction for the continuous clip** from the CAMERA RULE. A speaker may deliver the line while walking or riding; that is preferred. Two characters standing in place and talking, a static camera on a static scene, or "gestures" as the only motion is a structural failure: rewrite the beat before submitting. The keyframe must make that motion possible (a path to walk, a gate to open, an object in hand), so plan the initial pose as the **start** of the movement (mid-stride, hand on the gate, foot on the pedal).
- **ONE-ACTION BUDGET.** One main action plus one small follow-up, and no more. A prop may change hands or leave its container (pick up, hand over, lift out) in **at most one clip out of every three**, and that clip's camera is `the camera remains locked and static, maintaining the same framing and subject size` in both shots — never a tracking or panning move in the same clip. Standing up, sitting down, kneeling and turning around count as the main action; they cannot be combined with a pick-up. If a beat needs more, split it into two beats.
- **CONTINUITY (keyframe → clip).** The clip prompt's first lock sentence restates where every prop and animal is at the start, using the same words as the keyframe pose (`the puppy starts inside the blue dog bed`; `the cake box starts in the boy's hands`), and the main action must be physically possible from the keyframe pose in one movement. A prompt that has the boy holding the puppy while the keyframe shows it in the bed forces a teleport. Record `props_at_start` per beat in the prompt book and check that the clip prompt names the same location.
- **DIRECTION LOCK.** Every beat in which a person, animal or vehicle travels states the screen direction and keeps it for the whole film leg: `moves from screen left to screen right` (outbound) / `from screen right to screen left` (return). For a bicycle, scooter, cart or car add verbatim: `the front wheel leads; the bicycle moves only forward in the direction it faces and never rolls backwards or reverses; the background passes in the opposite direction`. The keyframe must show the vehicle already pointing that way with the front wheel, handlebar and rider's leading side visible (front three-quarter or rear three-quarter view, not a flat side profile — flat profiles are where the model reverses the motion). While riding, **both hands stay on the handlebar and both feet on the pedals**; any grab, wave or point happens only in a later beat after `brakes, stops and puts both feet on the ground`. A wobble or bump is shown by the basket contents tilting while the hands stay on the bar.
- **PATH LOCK.** Anyone who walks gets a named open route and a named stop: `walks along the open floor between the counter and the tables, and stops one step in front of the closed door, facing it; the door stays closed and he does not touch it` / `walks along the empty pavement beside the railing`. A door, gate or lid changes state only through a stated hand action in the same shot (`pulls the door open with his left hand`), and a person passes through a doorway only after the door is stated open. Furniture, walls and doors are solid: `nothing passes through the door, the counter, the tables or the walls` is written in the continuity lock of every indoor beat.
- **FREE-HAND LOCK.** For every held object write the holding hand AND the free hand: `[NAME] holds the [object] in [his/her] right hand only; [his/her] left hand is empty and visible [at his side / on the counter / on the pole]; [he/she] has exactly two hands and there is exactly one [object] in the clip.` Two hands may touch one object only when the action says so (`lifts the box with both hands`). Never write a hand action for a hand that is holding something, unless the object is first put down in a stated action. Without this, a second copy of the object or a third hand appears.
- **NO FINGER COUNTS.** Never write a gesture that depends on counting fingers (`holds up three fingers`, `a thumbs-up with one thumb`); the model miscounts. Use whole-hand gestures (`raises an open hand`, `points ahead with one finger`, `taps the map`).

**Objects and setting**

- **NEW-OBJECT LOCK.** Every clip prompt carries verbatim `Nothing appears that is not already in the reference frame: no new object, toy, vehicle, gate, door, furniture, animal or person materialises, and the setting stays the same place for the whole clip.` Every object a beat needs must be in the keyframe already (the keyframe prompt lists it), and a prop that enters the story later gets its own keyframe where it is visible from the first frame.
- **OBJECT-INTEGRITY LOCK.** Every beat that shows a vehicle or a key prop carries a part-count sentence: `exactly one bicycle with exactly one handlebar, one wicker basket and two wheels; no part duplicates, splits, merges or morphs`; `exactly one cake box, one lid, one ribbon`. Every clip prompt ends its lock block with `each person keeps two arms, two legs and one head throughout; hands stay attached to what they hold; nothing passes through anything`. Prefer props with few parts and simple silhouettes; avoid ropes, ladders, spokes in close-up and mirrored surfaces in the keyframe.
- **STABILITY LOCKS (every clip prompt).** After the actions, state in plain sentences what must not change during the clip: every carried or contained prop stays where it is ("the puppy stays inside the basket the whole time"), sizes stay constant ("keeps exactly the same small size … for the whole clip"), worn items stay on ("both helmets stay fastened on their heads for the whole clip"), parked vehicles stay still, doors stay in their state, and "exactly one" of each animal or prop with "no second one ever appears". The lock block of every clip prompt has this fixed order: **continuity sentence (where every prop starts) → wardrobe lock(s) → prop/size/state locks → direction lock (if anything travels) → new-object lock → object-integrity sentence**.
- **LANDMARK-ONCE RULE (keyframe prompts).** A landmark, vehicle, animal or prop is described in exactly ONE place in a keyframe prompt (in the setting string OR in the pose text, never both) and every later mention says `the same [X]`; a landmark described twice is rendered twice. The integrity sentence is written as a total: `Exactly one street clock in the whole frame — the same clock — and no second clock anywhere.` Build each setting string once in the prompt book with each landmark named once, and write the pose text without re-describing anything the setting already contains.
- **BLANK-SIGN RULE.** Negative wording ("no captions, labels, logos") does not stop invented lettering. Write the positive form in every keyframe prompt that contains a building, shop, vehicle or sign: `Every sign, awning, shop window, door panel, bus panel and route board is plain and blank — a solid colour with no letters, numbers, logos or symbols anywhere in the frame.` Do not use the words `shop sign` or `lettering` in a positive sentence, and do not name shops by type in the setting when a blank facade will do (write `a small shop with a blank green sign` rather than `a bakery`).
- **AUDIO NAMES NO OBJECTS.** The ambient-sound phrase must not name a sound source that is not in the keyframe (a "ticking clock" in the audio sentence puts a clock on the wall). Write sounds as qualities (`quiet indoor room tone`, `soft outdoor birdsong`), or name only a source the keyframe already shows (`the coffee machine hisses`).

**Shots, framing and camera**

- **ONE CONTINUOUS SHOT.** A 4–5 s clip begins with its selected keyframe and stays in the same shot, angle and place. Do not write `Shot 1`, `Shot 2`, `cut to`, `switch to`, `another view`, or a new character entrance. The speaker performs one small physical action while delivering one line. The listener remains visible in the same position, mouth closed. A camera may stay locked or track both people together gently; no reframing that hides and reintroduces them.
- **IDENTITY AND COUNT LOCK.** At the start of every clip prompt: `Animate only the two distinct people already visible in the selected keyframe: one [ADULT NAME] on [screen side] and one [CHILD NAME] on [screen side]. These are the same two bodies for every frame. No new person appears, and neither person is copied, replaced or transformed.` For a one-person shot, state exactly one visible person. Do not mention other human roles, even in a negative list.
- **PROP OWNERSHIP LOCK.** Name each unique key prop once, its initial position, owner and holding hand. Example: `The single wicker basket is in Elias's right hand; Noah's hands are empty. That same basket stays visible and is never copied or moved to another hand unless this beat explicitly shows one transfer.` When a prop rests on the ground, say so and do not also describe it as held. Do not repeat the prop as a new object in the setting or action.
- **FRAME AND CAMERA LOCK.** Use a medium-wide two-shot that keeps both whole bodies and the unique prop visible. Default: `One continuous locked camera shot, same framing and subject sizes throughout.` For walking, one gentle lateral tracking shot may follow both people together. Avoid mirrors, reflective panes and strong shadows that resemble additional people.
- **KEYFRAME FIRST.** For a later user-requested quality review, distinguish a defect visible from the first frame from one introduced by animation. During production, keep moving through batches without frame inspection.
- **SHORT PROMPTS.** Describe the visual state once and the one action once. Keep the voice anchor and exact spoken line. Repeating full descriptions of both people, objects, locations and camera moves across sections can invite duplicate interpretations.

## §4 Prompt templates

**Character reference image — one paragraph in the Image Prompt field, Image Type 3D, Use Creative mode on.** Make **one single full-body person** in a three-quarter view on a plain studio background. Do not make a three-view turnaround or collage: multiple reference figures can be copied into a scene. Include the fixed face, age, proportions and byte-identical wardrobe string. No props or other figures.

```text
3D Pixar-style animated feature character reference. One single full-body [NAME], a [AGE]-year-old [DESCRIPTION], standing in a natural three-quarter pose on a plain warm-gray studio background. [EXACT WARDROBE STRING]. Preserve [DISTINCTIVE FACE, HAIR AND PROPORTIONS]. One visible head, one torso, two arms, two legs. No other person, duplicate, inset, panel, turnaround view, prop, text or crop.
```

**Keyframe (scene) prompt in the Image Prompt field, Image Type 3D, Use Creative mode on, Use Consistent Character on = style opener + camera sentence + binding sentence(s) + start-of-motion pose/setting + style sentence + closing sentence:**

- Style opener (verbatim, first words of every keyframe prompt): `3D Pixar-style animated feature frame, high-end cinematic 3D animation.`
- Camera sentence: `Medium-wide shot at eye level, 16:9 cinematic frame.` (or `Medium tracking-shot framing …`, `Medium two-shot …`, `Over-the-shoulder …`).
- Binding sentence per reference (carries the byte-identical wardrobe string and the AGE/PROPORTION LOCK): `Reference image N is the canonical character sheet of [ID], a [age]-year-old [background] [boy/girl/man/woman] with [SKIN]. [He/She] is a [age]-year-old child with a child's proportions — head about one sixth of [his/her] height, slim limbs, standing about at [the adult ID]'s chest — not a toddler and not a teenager. / [He/She] is a full-grown adult about [N] cm tall. [He/She] wears exactly [WARDROBE_<ID>], nothing added, removed or recoloured. [He/She] has exactly two hands. Render exactly one instance of [him/her], preserving the reference face, apparent age, body proportions, hair, complete wardrobe and footwear; do not reproduce the reference background or add another view.`
- No-swap sentence (two-shots only, after both bindings): `The two characters never share, swap or copy any clothing item: only [A] wears [A's unique items]; only [B] wears [B's unique items].`
- Direction and integrity (only in beats with travel or a vehicle/key prop): `[Vehicle] points toward screen [right/left], front wheel and handlebar clearly visible, exactly one bicycle with exactly one handlebar, one basket and two wheels.`
- Start-of-motion pose and setting: the pose is the first instant of the beat's movement (mid-stride on the path, one hand on the gate latch, foot on the pedal, reaching for the object), expression, held objects with the holding hand and the free hand (`holding the same smartphone to his right ear with his right hand, his left hand empty at his side`), props and continuity state, then the setting string (each landmark named ONCE — LANDMARK-ONCE RULE — and referred to as `the same [X]` if the pose text needs it), light (`Sunny morning light, soft shadows.` adapt). **Every object the clip will use must be in this frame** (NEW-OBJECT LOCK), and the place of every prop/animal written here is reused word-for-word as the clip's continuity sentence.
- Landmark total (every keyframe with a landmark, vehicle or key prop): `Exactly one [X] in the whole frame — the same [X] — and no second [X] anywhere.`
- Blank-sign sentence (every keyframe with a building, shop, vehicle or sign — BLANK-SIGN RULE): `Every sign, awning, shop window, door panel, bus panel and route board is plain and blank — a solid colour with no letters, numbers, logos or symbols anywhere in the frame.`
- Style sentence (verbatim): `High-end cinematic 3D animated-feature rendering with refined studio craftsmanship and warm human appeal. Premium animated-film materials: nuanced matte skin with subtle translucency, natural color variation and peach fuzz; individually defined hair clumps and strands with fine flyaways; visible cotton knit, denim fibers, seams, folds and softly worn fabric; realistic moist eyes with restrained highlights; soft global illumination and contact shadows. Avoid glossy vinyl, plastic, wax, porcelain, rubber, toy surfaces and bobblehead anatomy. Render one single cinematic frame, not a sheet or collage.`
- Closing: `Exactly [one person / two people] in frame and no one else: no third person, no bystanders, no passers-by, no extras, no drivers, no faces in windows or doorways. No animals or birds. No captions, watermarks, duplicate figures, extra limbs or malformed hands.`

**Video/audio prompt — one continuous shot, short and concrete.** Paste this beat's exact text into Video and Audio Prompt immediately after accepting its keyframe, then set/read back the duration and create its clip before the next keyframe.

```text
Animate the selected keyframe as one continuous [SEC]-second medium-wide two-shot. There is one [ADULT NAME] at [screen side] and one [CHILD NAME] at [screen side], the same two bodies throughout. [ADULT] wears [WARDROBE_ADULT]; [CHILD] wears [WARDROBE_CHILD]. The single [KEY PROP] starts [EXACT POSITION/OWNER/HAND FROM KEYFRAME] and remains that same object throughout. [ONE SMALL ACTION POSSIBLE FROM KEYFRAME]. [SPEAKER VOICE ANCHOR] says [ALLOWED DELIVERY], "[EXACT LINE]." [LISTENER] watches silently with lips closed. One continuous locked camera shot; both people and the unique prop remain visible in the same framing. No person or prop enters, duplicates, disappears or changes identity. [SHORT AMBIENCE]; only [SPEAKER] speaks; clean dialogue; no music. End with [SPECIFIC POSE/PROP LOCATION].
```

For a walking beat, use a single gentle lateral camera track that follows both people together. For a pick-up or hand-over, keep the camera locked and state exactly one transfer. Do not ask the model for a cut, a second angle, or a new scene in the same 4–5 s clip. Keep the cast and prop counts explicit, but do not repeat full visual descriptions more than once. The prompt book records the exact submitted text, not just a longer planning draft.

## §5 Run directory and records

Create a folder named `<run_name>_<RUN_ID>` inside the working directory you were started in (or the location I name) — never a folder another run may be using (RUN ISOLATION rule 1). It holds three files: `prompt_book.json` (story, identity records, voice anchors, wardrobe strings, sheet prompts, and every beat with its keyframe prompt, video/audio prompt and seconds), `WORKFLOW_STATE.json` (every stage: the settings read back, the names and statuses of every asset created, durations, timeline order, export), and `PROCEDURE_LOG.md` (anything that differed from this document, in plain words). Write the state before and after every submission. If you cannot save files, keep the same facts in your progress messages instead.

## §6 Stage 0 — Preflight

1. Generate `RUN_ID`, create the run folder, and write `WORKFLOW_STATE.json` with `run_id`, the simple title without a suffix, the generation-tab ID if available, and an empty entry for each stage.
2. Reuse the first open signed-in VideoExpress tab as the generation tab when it is not being driven by another active run. Confirm editor title, signed-in account and **Create with AI**. Record its tab ID. Do not navigate or reload it if this run's dialog and references are already selected. If another active run owns it, open one dedicated generation tab for this run and record that ID. Open at most one separate monitor/assembly tab; do not open a tab for each image or video. Check **My AI Images** and **My AI Videos** in the monitor/assembly tab. At resume, restore this run's recorded generation tab first.
3. Open **My Videos** (the exports list) and note the name of its most recent entry, so this run's export can be told apart from older ones later.
4. Write the prompt book: the identity records, the two voice anchors, the two `WARDROBE_<ID>` strings, the direction and integrity sentences, the setting strings (each landmark named once), the two sheet prompts, N beats that each pass the MOTION RULE and the CAST LOCK (no third person anywhere in the story), the word limits, the keyframe prompts and the single continuous-shot video/audio prompts. Assemble every prompt by pasting the stored lock strings unchanged, so a paraphrase cannot slip in. Run the §3 and §9 text checks on every beat before touching the app, and fix the prompt book first if any check fails.

## §7 Stage 1 — Character sheets (one per character)

1. In the persistent generation tab, open **Create Video From Prompt** only if this run's dialog is not already open. On a new run, its candidate strip must contain no foreign candidates; if it does, use a fresh dedicated generation tab without disturbing the existing tab. On same-run resume, preserve this run's candidate strip and reference slots; verify them against `WORKFLOW_STATE.json` instead of reloading.
2. Options (every time the dialog opens): `__imageOptions()` — it selects Image Type `3d` (or a Pixar-named option if the dropdown has one; log the option list once), sets `image_creative_mode` ON, `auto_enhance_prompt` OFF, `shared` OFF. Ratio buttons "Landscape 16:9" / "Vertical 9:16" at the dialog top (Landscape is default). Read the returned object back and record it.
3. `setTa(document.querySelector('#opt_prompt'), <single-person reference paragraph starting with "3D Pixar-style animated feature character reference">)`.
4. Click **Create Image**. Creative mode takes 20–60 s. Wait until a new full-size result image for this submission appears in the dialog (one that was not there before you clicked). Record the submission in the state file.
5. Save: the sheet result slides have NO save button of their own — the `.image-slider` has one shared `.button-save-image` that acts on the ACTIVE slide. `slideTo` the slide whose `img.src` carries THIS job's uuid, assert it is `.swiper-slide-active`, then click that save button (never a document-wide first/last save button, never without the active-slide assertion). Alert text: `Your image has been saved in your Media Library in the category "My AI Images".` Then `await __findImageByBytes(__s3(job_uuid))` → record `library_id`, `fileName`, `size`. An `error` result means no exclusive match — re-query per the helper; never fall back to the newest item.
6. Repeat for the second character in the same dialog. Identify the new result by a preview `img` whose uuid was not present before the click (keep a `seen` set), not by "the active slide".
7. The saved single-person portrait IS the consistent-character reference. There is no in-app upload for a cropped view; do not attempt one.

## §8 Stage 2 — Create the current beat's keyframe, then continue immediately to Stage 3

For each beat in the current batch, finish its keyframe here and submit its video in §9 before starting the next beat. Prepare only one unsent beat image at a time. Do not generate all keyframes in advance.

1. In the open dialog: re-run `__imageOptions()` if the dialog was reopened, then `cb('use_consistent_character',true)`. If the consistent-character Disclaimer dialog with "I Agree" appears, click "I Agree" (covered by GO; the user accepted this dialog on 2026-09-17). If a DIFFERENT or NEW agreement appears, stop and show it to the user. Two reference slots appear: buttons "Reference Photo" and "Reference Photo 2".
2. References: select each saved character sheet once in **Reference Photo** and **Reference Photo 2**, then keep both slots selected in this dialog across all beats. Record tab ID, sheet library IDs and thumbnail fileNames in `WORKFLOW_STATE.json`. Before each Create Image, read the two slot thumbnails and compare their fileNames with the recorded values. Re-select a reference only when a slot is empty or mismatched. Never clear both slots merely to advance to the next beat.
3. `setTa('#opt_prompt', <keyframe prompt starting with "3D Pixar-style animated feature frame">)`, confirm `input[name=image_creative_mode]` is checked, and click `.button-generate-image-submit`. Wait for this beat's two `.swiper-slide-pair-item` results (the placeholders may take 5–40 s to resolve). Keep the beat's references and prompt unchanged until its candidates are identified and a candidate is saved. Do not submit another beat's image yet.
4. Read the new candidate uuids from the pair items at index `n0` and `n0+1`, where `n0 = .swiper-slide-pair-item.length` was recorded immediately before that beat's submit (never "the last two" — later submits shift the tail). Each uuid must be new to this run's state. Record both. Select candidate 1 by default. If a duplicate main character or key prop is obvious in its existing strip thumbnail, select candidate 2 if it looks better. Do not open a separate preview or regenerate solely for appearance. `pairItem.click()` → it gains class `selected` (verify by `img.src`).
5. Save with the Save button INSIDE the chosen item: `pairItem.querySelector('.button-save-image').click()` → `await __findImageByBytes(__s3(chosen candidate uuid))` → record `library_id`, `fileName`, `size`. The match must be exclusive; on `error` re-query, never take the newest item. Never use a document-wide nth `.button-save-image`. Before every submit, `__slots()` must equal this run's sheet fileNames in the beat's `cast_ref_order` (slot 1 = first cast member, slot 2 = second or empty); clear and re-pick a slot that differs.
6. With this beat's selected candidate saved, continue immediately to §9: enter this beat's video/audio prompt, set and read back its manual video length, confirm the same candidate is highlighted, and click Create Video once. Do not start the next beat's image until this video submission is acknowledged and recorded. If the dialog was reopened, use this beat's saved keyframe through Use from Library instead of regenerating the image.

## §9 Stage 3 — Submit the current beat's video, then advance in batches of five

For the current beat, immediately after §8 has saved its keyframe and before §8 begins the next beat:

1. Text checks (no app call): the exact submitted video/audio prompt contains `one continuous`, the named visible cast count, the single key prop's owner/location, one main action, the exact quoted line and byte-identical speaker voice anchor, one camera instruction, the listener's closed mouth, the final pose and the planned duration. It contains no `Shot 1`, `Shot 2`, `cut to`, second angle, new person entrance or new prop. Confirm the selected keyframe id matches this beat and the prompt's starting positions match the planned pose. Store this exact prompt as `submitted_video_prompt` in the run state. Fix a mismatch before Create Video.

2. Call (tab 1): `await __clipSubmit('<candidate uuid>', '<video/audio prompt>', <4|5>)`. Internals: selects the pair item; forces `talking_video`, `narration_video`, `video_only`, `shared` OFF and `advanced_mode`, `manual_video_length` ON; `enhance_video_prompt` OFF; sets `#opt_video_duration` with the native setter and reads it back; sets `#opt_video_prompt`; refuses (`error:'precheck failed'`) if any read-back differs; otherwise reads the current footer uuid, clicks `.button-generate-video-submit`, waits until the footer `Video: <uuid>` CHANGES (up to 20 s), then resolves the library item whose `uuid` equals that new footer uuid (`__findClipByUuid`) and returns it with any alert text. Expected alert: `Your video will appear in your Media Library under the My Media tab when it's ready.` Record `library_id`, `fileName`, `video_uuid`, and the read-back state. A result with `error:'footer uuid did not change'` means nothing was attributed — inspect per step 6 before any resubmit.
3. If `state.slider.value` did not equal the beat's seconds (the setter did not take): use the keyboard method **(prod 2026-09-04)** — click the slider thumb, press `End` (value 10), press `ArrowLeft` (10 − N) ÷ step times, read `.value` live until it equals N — then call `__clipSubmit` again (it re-sets and re-checks; nothing was submitted on a precheck failure). Log which method worked.
4. If the alert says `Please create scripts for the actors.` the Lipsync HD checkbox was on: read `input[name=talking_video].checked`, set it OFF, and resubmit once.
5. After five video submissions have been acknowledged, or after the final partial batch, use tab 2 to monitor the batch: `fetch` the My AI Videos list and check every recorded id for `status: "completed"` and a numeric `duration` (ms) ≈ seconds × 1000 (+~42 ms). Poll every 30 s; never resubmit because polling is slow. Record the first completed clip's exact `duration` and use it as the expectation for the rest. Keep at most five accepted, unfinished video jobs, including corrections.
5b. **Source-frame check** for every clip as soon as it is completed: in My AI Videos, confirm the clip's thumbnail shows this beat's keyframe (same pose, setting and cast). If it shows a different frame, the clip was animated from another candidate: reselect this beat's candidate (§13 1b), resubmit once, and check again. On a second mismatch, stop and ask me before placing that beat on the timeline. This is a quick provenance check in the existing library entry; do not play the clip or inspect multiple frames.
6. If the call times out at 45 s: do NOT resubmit. Inspect: read the footer `Video: <uuid>`; if it differs from the uuid recorded before the click, `__findClipByUuid` it and record the item. Only when the footer is unchanged AND no My AI Videos item created after the click has a `name` beginning with this beat's exact prompt text, repeat step 2. A "new processing item" that is not tied to this footer uuid may belong to another run — never adopt it.
7. Once this beat's Create Video submission is acknowledged and recorded, return to §8 for the next beat if fewer than five videos have been accepted in this batch; do not wait for individual renders. When the batch reaches five accepted videos (or all remaining beats), complete steps 5 and 5b for every batch clip and resolve any failures under §13 before starting the next batch. After every beat is complete, proceed to §10.

## §10 Stage 4 — Timeline

0. Leave the persistent generation tab open with the Create Video From Prompt dialog, settings and selected references. In the separate monitor/assembly tab, click header **New** and confirm a fresh editor with zero visible `.brick`. Never click New in the generation tab; it would discard the selected references.
1. In the monitor/assembly tab, open **Media Library → My AI Videos**. Do not close the generation dialog. Tiles are `.library-item[data-ident=<videoId>]`; find each by its recorded ID, not list position. The panel scrolls; older clips may need **More**.
2. **Right-click → Add to Timeline only. Never drag clips.** For each recorded clip id **one at a time in story order**, find its Media Library tile, open its context menu (right-click / `contextmenu`), and click the visible **Add to Timeline** action `a[data-action="add-to-timeline"]`. In the documented browser helper, call `await __addToTimeline(id)`, which dispatches `contextmenu` on that tile and then `mousedown`/`mouseup`/`click` on that menu anchor (clicking its parent `li` does nothing). Wait for the new `.brick.video`; verify the brick count rose by exactly one, the new brick belongs to the recorded clip, and it is on **track 1** before adding the next clip. No drag-and-drop, mouse dragging, pointer dragging, Sortable action, or manual drop position is permitted at any point, including retries and recovery. If the context menu or Add action fails, re-query that tile and menu and retry the same right-click action; if it still cannot add, checkpoint and report the blocker rather than dragging.
3. Verify order once: for every visible `.brick`, read `getComputedStyle(brick.querySelector('.content')).backgroundImage`, extract the `\d{10}_[0-9a-f]+` fileName, sort by `getBoundingClientRect().x`, and compare to the recorded fileNames in story order. The brick count must equal the beat count and every fileName must be in this run's recorded clip set — a brick with any other fileName is a foreign clip (RUN ISOLATION rule 3): delete it with the track "Delete" control. Fix any order mismatch by deleting the wrong bricks and re-adding. Before step 2 also re-fetch each recorded clip id and assert `uuid === recorded video_uuid` (rule 6).
4. Click the first visible `a[title="Auto Align Clips"]` once. After alignment, confirm all planned bricks remain on track 1 in story order, with no extra or missing bricks. If alignment changes order, use the same right-click Add to Timeline process to rebuild; never drag to repair it.

## §11 Stage 5 — Save and export

1. In the monitor/assembly tab, check that `<Title>` does not name another saved project. On the fresh editor, click **Save** to open the project-name dialog; if another project is loaded, use **Save Project As**. Enter `<Title>` with no date, time or RUN_ID and save once. Confirm the success message and `document.title === 'Video Express - <Title>'`. Do not save over another project. Leave the generation tab open.
2. Click **Export Video**. Set the export name to `<Title>` with no date, time or RUN_ID; select High quality, FullHD resolution and mp4 format. Read back each setting, then click **Create** once.
3. In the monitor/assembly tab, wait for the export queue entry for this run to finish. Open **My Videos** and find the entry with exact title `<Title>` and an output ID above the floor recorded at Stage 0. Record that output ID and the completed entry in `WORKFLOW_STATE.json`. Ignore other runs' entries; never identify this export solely by list position.
4. Do not click **Download**, fetch the MP4, or run `ffprobe`. Leave the finished export in VideoExpress. Report its in-app title and output ID; report resolution as the selected export setting and runtime as the sum of completed clip durations, clearly marked as estimates rather than measured file properties.

## §12 Deliverables and final report

Produce, then send in the final message:

- The finished VideoExpress export title and output ID. The film stays in **My Videos**; do not download it.
- `prompt_book.json`, `WORKFLOW_STATE.json` and `PROCEDURE_LOG.md` as local text records. Do not download keyframes or create a storyboard during the run.
- Keep the keyframe table in the local prompt book. Include it in chat only if the user asks:

| Time | Shot | Keyframe attempt | Speaker | Dialogue | Motion / camera |
|---|---|---|---|---|---|
| 0–5.0 s | B01 | attempt 1 (cand 1) | … | … | walks through the gate; camera tracks beside |

- Save the provenance chain in `WORKFLOW_STATE.json`; link that file in the final report rather than pasting every beat's identifiers into chat.
- A candid QA section: planned runtime, summed completed-clip durations, selected export resolution, retries, extra library items, Image Type setting, prompt-text checks and source-thumbnail checks. State which properties were checked in app and which remain unverified. State that visual quality, cast/prop count through the clip, lip-sync, voice consistency and measured MP4 properties were not reviewed during production.

## §13 Retry ladder (per asset: 1 initial + at most 2 corrections)

0. Appearance issues noticed during normal work are logged briefly and do not trigger retries or block export. Do not start a visual QA loop. Only app failure, missing job, wrong source keyframe or unusable duration/empty render triggers the corrections below.

1. App error/alert on submit → read the alert text; fix the named cause (`Please create scripts for the actors.` = Lipsync HD was on → turn `talking_video` off; a length complaint → re-set the slider); resubmit once.
1b. `selection lock failed` or `BLOCKED` from `__clipSubmit` → the strip did not take the click or the payload carried another image: scroll the pair item into view (`scrollIntoView({inline:'center'})`), click its `img` directly, wait 1 s, call `__clipSubmit` again (it re-runs `__activate`). If it fails a second time, record tab state, reload the generation tab as a recovery step, re-paste helpers, reopen the dialog, re-select the two recorded references and the saved keyframe through "Use from Library", then submit. Never submit with the wrong item selected.
1c. Wrong source keyframe: if the recorded source id or the existing library thumbnail clearly belongs to another beat, reselect this beat's candidate and resubmit once. If it still uses the wrong source, checkpoint and report before assembly. Do not download frames or numerically compare each clip during production.
2. Library item `status` becomes anything other than `processing`/`completed` (e.g. `failed`, `error`) → resubmit the same request once; if it fails again, resubmit with the prompt shortened by removing the environmental-motion clause (keep the locomotion action, the camera move and the quoted line); then checkpoint and report.
3. Job missing: refresh the list once, inspect three times over 90 s; if still missing, treat as a true blocker.
4. Selector missing: re-query after a short wait and inspect the visible modal. Preserve the generation tab, selected references and candidate strip. If that tab is truly frozen, record its state, recover it once, then re-select the recorded references and saved keyframe through **Use from Library** if needed. Do not open each asset in a new tab.
5. Never resubmit merely because polling is slow; never create duplicate images "to check".

## §14 Known unknowns (do not guess; observe and log)

- Image Type dropdown on 3.5 (production, 2026-09-25): `human | 2d | 3d | photorealistic | other`, no Pixar-named option → `3d`. `__imageOptions()` still logs the list in case it changes.
- `#opt_video_duration` accepted the native setter on production (2026-09-25, read-back 4/5 on all 39 clips); the keyboard method remains the fallback.
- `image2video` clip jobs do not appear in `/user_queue` on production either. Monitor via the library item `status`.
- Measured on production (2026-09-25, 39 beats): 5 s manual length → `duration` 5041.667 ms, 4 s → 4041.667 ms; sheets ≈20 s; keyframes 10–40 s (39 in ≈10 min with 5 in flight); clips 2–3 min each (39 in ≈25 min with 5 in flight); export of 39 clips ≈2.5 min; output 1920×1080 25 fps with audio; 181.58 s for 39 clips (sum of clip durations ±0.05 s). Sheets come back 1920×1088.
- Source-frame calibration (production, 2026-09-25, full-size keyframes): a correct clip's first frame differs from its own keyframe by 1.3–2.0 and from every other keyframe by ≥ 40. The earlier 11–17 readings (Melon Cart) were measured against the recompressed dialog preview.
- The Consistent Character disclaimer did not appear on production on 2026-09-18 or 2026-09-25 (same account); clicking "I Agree" on that same consistent-character disclaimer is covered by GO if it does.
- UNKNOWN: whether the single continuous-shot form changes clip render time; log the first five clip timings of the next run.
- UNKNOWN: the final MP4 dimensions of a portrait (Vertical 9:16) export without downloading it. Log the Export dialog's size options and selected value; do not claim measured output dimensions.

## FINAL REMINDER

The user approves this run once, with GO, after seeing the run plan. Then create both character sheets; for each beat create and save its keyframe, set its video/audio prompt and duration, and submit its video before preparing another beat. Finish each batch of up to five clips before beginning the next; then assemble, save and export. Ask again only for something GO doesn't cover, a real blocker, or an approval prompt from the host or tool runtime.
