# Cinematic Finishing

## Full AV observation coverage (R3)

Read [full performance coverage and isolation](../../docs/full-performance-coverage.md). Bind FilmReview with bind_full_performance_review from all performance-bearing source fragments. performance_required_beats is the full set, not a highlight reel. Keep required channel coverage per fragment: silent actions require visible evidence, spoken/shared vocal responses also require listening. One missing ordinary Beat yields AV_PERFORMANCE_COVERAGE_INCOMPLETE; UNKNOWN is never PASS. A full design manifest is only an observation obligation, not playback evidence. Preserve R2 evidence when a later semantic defect is found; report the finding with actual source context and repair owner.

## AV performance alignment facet (R2)

Read the [shared performance contract](../../docs/cross-modal-performance-direction.md). Use existing FilmReview / FilmFinding, not a parallel AV review contract. Compare pinned planned DPD/Director/visual/voice with actual RealizedPerformanceSnapshot and listening evidence across amplitude, control, target, physical/vocal effort, breath, timing, pause, spatial reach, partner cue, release, continuity, native suitability and meaning. Include byte hash, speaker/Beat/line, observed time interval and evidence reference. Missing evidence remains UNKNOWN.

Review every required performance-bearing Beat; a later PASS cannot erase an earlier failure. Each finding names the visual, audio or Director repair owner; DPD review is reserved for actual source-psychology conflict. Review repaired bytes again before adoption. DESIGN_ONLY evidence never proves observed media; OBSERVED never means ADOPTED. Full native reuse needs listening coverage; a local sound defect cannot authorize full dialogue replacement. Contract-valid alignment does not establish moving or artistically successful acting.

## Opt-in Director authority

Keep EditorialRhythmPlan, PictureEditPlan, SequencePackage and FilmReview as the original owners. Director intent governs acceptance without a parallel edit plan or review. Return existing output/evidence references; use the optional FilmReview director facet for actual-media intent coverage and causal disposition. A design-only judgment stays in Bible review, never a fabricated AV review. Director approval does not imply user adoption, and technical success does not imply Director approval. Native-audio policy and source-preserving finishing remain unchanged.

If the user later adopts an `authorial-voice` candidate, preserve its literary text,

provenance, intent, form and semantic position. Finishing owns its actual screen/sound

delivery (subtitle, black, overlay, reading or silent display) and timing. The presence

of an unadopted literary sidecar does not authorize adding a coda to the film.

Recover the selected assembly with `work.get_work`, its actual `shot.get_shot`

and `scene.get_scene` relations, and `media.get_media` / `media.resolve_media`.

Use `media.list_media` for scoped source material discovery. Source bytes, hash,

duration, tracks, timeline and ownership must agree before editing. Preserve the

original. A filename is not selection or recovery authority.

## Scene Sound Plan

Plan the continuous dramatic passage first, independently of Shot file edges:

Dialogue; Diegetic / Source Sound; Persistent Ambience; BGM; Transition; Silence.

Give each meaningful cue a source, narrative function, passage range, entry/exit

and changes in distance, direction, spectrum or attention. One cue can cross

several Shots and adjacent Scenes. A cut does not restart or stop it. Use J/L

cuts, crossfades and envelopes only where they serve space, action or attention.

Do not mechanically loop a short vocal/music phrase to fill a longer passage.

Default priority is Dialogue > narratively important diegetic sound > persistent

ambience > BGM. Protect the actual words and synchronized action sounds. Duck

lower layers around measured dialogue, with natural ramps. Do not mute mixed

dialogue to remove an overlapping effect. Seek original tracks first; if only a

mix exists, use a localized, evidenced repair and disclose its collateral limits.

An isolated wrong sound does not justify inventing a new battle or changing story.

## BGM decision

Choose NO_BGM, SUBTLE or ACTIVE for the Scene/passage. If no concrete dramatic

function is identifiable, choose NO_BGM: this is a complete artistic decision.

Distinguish it from unavailable music. For music, state whose situation it helps

the audience understand, its entry/exit, cross-Shot scope, and how dialogue and

important source sounds retain attention. An emotion label alone is insufficient.

Do not automatically score sadness/battle, cover editing errors, or fade every

Shot independently. Diegetic singing is not automatically BGM.

Sources may be EXISTING_MEDIA or LOCAL_LICENSED with traceable usage rights;

GENERATED is a future capability seam, never an implicit fallback. Retain any

adopted local material through `media.import_media`, verify full hash/get/resolve,

then use its stable Media ID and source ranges. Missing material stops only the

dependent finishing operation with a precise source/range recovery point. It

never authorizes new picture, voice or music generation.

## Local execution and review

The Host translates the plan into a local recipe: verified inputs, source trims,

placements, envelopes, replacement windows, protected dialogue and remux. Use

the packaged `scripts/finish.py` entry and [Host contract](../../docs/cinematic-finishing-host.md).

The Core makes creative decisions; the Host handles extraction, trim, fades,

crossfade, ducking, mixing, probe and video stream copy. Verify compressed video

packets AND timestamps; a changed container hash is expected. Do not re-encode

picture as a convenience. Preserve original audio outside approved edits.

Review the full passage at normal playback, especially cue continuity, dialogue,

transitions, perspective and unwanted sound sources. Tiny noise/loudness

differences alone do not block. A major finding states observed sound/picture,

broken requirement and narrative consequence. Re-plan locally in scope without

repeated creative approval. Do not infer failure or PASS from absent evidence.

ASR, waveforms and spectral checks support localization, not listening. If the

Host cannot actually hear, keep audio review UNKNOWN and retain a clearly named

candidate; never claim final audible repair. Seek available observation first.

## Persistence and recovery

Use `work.save_work` and `scene.save_scene` to merge the current finishing

revision and references into existing content (save replaces content: preserve

unrelated fields). Keep source Media/hash, scope, sound plan, compact numeric

recipe with stable source IDs/ranges, derived Media/hash, review and userAdoption.

Local commands/PCM/probes are working artifacts, not the only recovery memory.

Keep historical revisions; changing a sealed recipe needs a new revision.

Use the shared import/get/resolve/full-hash/business-binding completion for the

new derived Media. A retained UNKNOWN candidate is not an adopted final. Host

selection and the user's eventual USER_SELECTED are distinct. Repeating the same

revision reuses the same Media; ambiguous imports are queried before any write.

Storage failure recovers identical output, never generates another picture.

Completion states exactly what was rendered, heard, verified and still unknown.

## Long-term BGM retrieval and rights

Decide NO_BGM / SUBTLE / ACTIVE before retrieval. NO_BGM skips music search,

selection and assembly. Otherwise call `asset.search_assets(query="BGM",

asset_type="AUDIO_INPUT")`, retaining only `creativeKind=MUSIC, role=BGM`.

`creative_assets.search_bgm` applies optional mood/narrative-function filters and

returns explainable candidates; assess energy, dialogue compatibility, duration,

entry/exit and rights. Search rank never makes the final choice; listen when needed.

UNKNOWN rights remain discoverable memory with productionEligible=false. Production

requires VERIFIED source/license/commercialUse/attribution plus bound durable

AUDIO Media. Refresh `asset.get_asset` rights before a new production, verify

`media.get_media`, resolve and full hash. Never infer rights, BPM or instruments.

Explicit selection uses `creative_assets.select_bgm` and records assetId,

assetFingerprint, mediaId, contentHash, selectedRange and reason. Each BGM recipe

layer retains `bgmSelection`, `bgmAsset` and `bgmMedia` snapshots. Existing render

validates rights, ranges and lineage before even reusing a cached output; normal

full-byte hash checks remain mandatory. Missing/unknown rights stop BGM execution.

Metadata edits never regenerate audio. See [creative memory contract](../../docs/creative-assets.md).

## Picture Edit Plan

After actual performance review, use the [picture-edit contract](../../docs/dramatic-peak-editorial-contract.md) and typed PictureEditPlan. Select sourceIn/sourceOut by information and measured action, rather than always using the whole generated file; record cut reason, reaction hold, match action, audio carry and pace function. Verify Media ID/hash/range and protected dialogue through `production_design.picture_edit_handoff`. Unknown listening remains DRAFT. This extends picture planning only; the existing sound renderer's source-packet preservation is unchanged. A picture assembly is separately authorized and produces a derived Media. Do not rewrite Script peaks, alter original AV or add music to manufacture a missing payoff. Review monotony, overcutting, missing reactions/detail/establishing context and contrast across the passage.

## Sequence production handoff

For authorized picture assembly, use the bounded local [sequence execution and review contract](../../docs/sequence-production-contract.md) and scripts/edit_picture.py. Reuse PictureEditPlan; hard picture cuts and native audio trims produce a new candidate. Then fulfill sound bridges, retain Media and review the complete rendered passage. Whole-film observation and findings are source-hash pinned; stills and technical checks cannot grant full AV review.

Consume executable Sequence audio/edit obligations separately from design readiness. Bind the actual output hash to FilmReview; UNKNOWN sound or missing normal AV coverage cannot become REVIEWED. Keep produced, reviewed and user-adopted states distinct.

## Intended transitions are upstream requirements

Consume shot-design's EditorialRhythmPlan.transitions as intended continuity, including time/space and sound carry. Finishing owns the actual measured-media cut and PictureEditPlan. Do not treat a planned match action or prelap as already observed or executed. Return infeasible continuity to its owner and retain actual Media evidence.
