Dependency graph

Interactive map of the generation graph: pick anything you can edit and see which prompts, sheets, stills and clips go stale.

Every generated artifact stores a hash of the inputs it was made from. Staleness is never a flag we set: on every read we recompute the hash from the current inputs and compare. A mismatch is stale. A row with no stored hash is untracked and never stale. Versioned things (green border) keep every generation as a row and a pointer picks one. Renders record which version of a prompt or sheet they used, so selecting a different version is what makes them stale, not editing the text.

Cast onto a character automatically at the Script stage or by hand; casting copies their look, performance and voice onto the character once. These fields only reach a sequence through a regenerated talent sheet: edit the description and the character keeps the old face until the sheet is redone.TalentA reusable location from the team library, matched onto a sequence location automatically or by hand. Its fields only reach a sequence through a regenerated reference image.LibrarylocationA team or system style in the catalog. Picking it copies its config onto the sequence; the catalog row is never read again.CatalogstyleExtracted from the script at the Script stage, rewritten by casting when a talent is matched, then yours to edit. A voice-only character (a narrator) has a row but never a sheet.CharacterExtracted from the script at the Script stage, linked to a library location when one matches, then yours to edit.LocationA prop, effect, sound or clip referenced by @token. Detected in the script at the Script stage or added by hand, then yours to edit.ElementThe look and motion config snapshotted onto the sequence: derived from the script by the auto style, or picked from the catalog.StyleThe lines spoken in a shot, assigned by the shot-list call at the Script stage. Wording rides the script (and so the motion prompt); the bound voice identity rides the clip.DialogueThe talent as a sequence sees it. A cast character usually reuses this sheet as its own and always draws from it, so "the talent changed" means "the selected talent sheet changed".Talent sheetTurnaround sheet for a character in this sequence. When cast, it is usually the talent sheet reused; a costumed one is generated only when the role's clothing or features diverge from the talent.CharactersheetA designed ElevenLabs voice for a speaking character. Bound on the clip like a character sheet on the still — the LLM never sees the id, so a voice change does not rewrite the motion prompt.VoiceThe library location as a sequence sees it: the location sheet draws from it and folds its hash in.Librarylocation refReference image for a location in this sequence.LocationsheetThe text the still is rendered from.VisualpromptThe text the clip is rendered from.MotionpromptOne prompt for the whole sequence.Music promptThe rendered start frame for a shot.StillThe rendered video for a shot.ClipThe generated score.Music trackThe stitched MP4.Export

Music track

generatedversioned — sequence_music_variantsoptional — when music is onsequences.musicInputHash (written, never read)

The generated score.

Counts

The check compares these. Change one upstream and this goes stale.

  • Nothing is compared today

Does not count

Change these freely. Nothing goes stale.

  • Music prompt, tags, duration and music model: the hash is written and never compared

Regenerate this and these go stale

  1. in the input hash — the music URL

Goes stale when any of these change

Nothing. It is never flagged stale.

Connected, but not tracked

  • not tracked — a gap — in the track hash, which nothing reads
  • not tracked — a gap — the track is never flagged; Update all at music depth regenerates it when the prompt regenerates

What "Update all" regenerates

The depth picker is cumulative. Each rung includes the ones above it, and no rung ever creates an artifact that does not exist yet.

  1. 1.Prompts only — Rewrites stale visual and motion prompts. Nothing renders.
  2. 2.Prompts + images — Also re-renders a still that is stale, or whose prompt was just rewritten. Never renders a first still.
  3. 3.Prompts, images + videos — Also re-renders a clip whose prompt or still changed in this run, or whose manifest already diverged. Never renders a first clip.
  4. 4.Everything, incl. music — Also rewrites a stale music prompt, then the track if one exists. Never a first track.
