feat(cinematic): R10–R14 grade/cadence/edit rules + 420p compat fix
Add five source-adaptive cinematic rules, all content-agnostic and
fail-soft, derived from a web review of the film look and how consumer
AI editors (DJI LightCut, Insta360) auto-edit:
- R10: 24fps cinematic cadence (output frame rate 30 -> 24)
- R11: filmic tone-curve grade (lifted toe + highlight roll-off);
optional licensed film LUT via lut3d, gated on a .license.txt
sidecar (fails closed, no unlicensed asset applied)
- R12: shutter-angle motion blur (tmix), toggle
- R13: beat-synced cuts — snap cut boundaries onto the score's beat
grid (HighlightBeatSync + tools/beat_detect.py, librosa)
- R14: subject-tracking reframe — follow the detected subject instead
of a static crop (HighlightSubjectTracker + tools/subject_track.py,
YOLO/AGPL, non-commercial); renderer subjectFollowFilter
- Fix: pin -pix_fmt yuv420p on every encode pass (was yuv444p, which
browsers/QuickTime reject)
R13/R14 are opt-in flags, on in localpoc. mvn verify: 288 tests green.
E2e bowling re-render verified: 24fps, yuv420p, -16.0 LUFS, 3 cut
boundaries beat-snapped, all 5 shots subject-followed.

moondream2 is Apache-2.0 (commercial-friendly, unlike the CC-BY-NC audio models).
|
||||
- **Source caveat:** a director can only cut what was filmed. If the camera never shows the pins, no tier can.
|
||||
|
||||
## R10 — Cinematic cadence: 24 fps ✅
|
||||
- **Why:** 24 fps (with a ~180° shutter) is the film-standard motion cadence used by the overwhelming majority
|
||||
of theatrical productions; 30 fps reads as "video". Output frame rate default moved **30 → 24**
|
||||
(`editing.output-frame-rate`, `VideoClippingProperties`). Generic, content-agnostic — one global knob.
|
||||
- Verified: a styled segment renders `r_frame_rate=24/1`, `nb_frames = 24 × seconds`.
|
||||
|
||||
## R11 — Filmic grade: S-curve tone + optional licensed LUT ✅
|
||||
- **Built-in grade (no external asset):** each beat now applies a **filmic tone curve** — a lifted toe
|
||||
(shadows never crushed) plus a rolled-off highlight **shoulder** (highlights compressed, not clipped) — which
|
||||
is the core of the "film look", on top of the teal-shadow / warm-highlight ("teal-orange") colour language.
|
||||
Replaces the old linear `curves=all='0/x 1/1'` ramp. Still **exposure-preserving** (mids ≈ 0.5, gamma ≥ 1):
|
||||
measured on bowling, source mean luma 112 → graded 121 (toward the 120 target), never crushed.
|
||||
- **Optional film-emulation LUT (`editing.film-lut-path`):** when it points to a readable `.cube` that has an
|
||||
adjacent, non-blank `<name>.license.txt` sidecar (same provenance discipline as generated assets), the
|
||||
renderer applies it via `lut3d` and **suppresses** the built-in colour moves (no double-grading), keeping only
|
||||
sharpen + vignette. Empty by default → built-in grade; **fails closed** on a missing/unlicensed LUT, so no
|
||||
unlicensed asset is ever applied. This is the upgrade path to real film color science (e.g. Kodak 2383) once a
|
||||
commercially-licensed LUT is provisioned.
|
||||
|
||||
## R12 — Motion blur: shutter-angle emulation ✅
|
||||
- **Why:** film's ~180° shutter produces natural motion blur; sharp digital frames strobe at 24 fps. Styled
|
||||
shots now blend each frame with its predecessor (`tmix=frames=2`, normalised so static frames are unchanged;
|
||||
only moving pixels gain a short trail). Toggle `editing.cinematic-motion-blur` (default on).
|
||||
- **Honest limit:** on already-soft / low-resolution source (e.g. 576p phone footage) motion blur can further
|
||||
reduce perceived sharpness — it most helps crisp, high-shutter footage. Disable it for soft source.
|
||||
|
||||
## R13 — Beat-synced cuts: cut to the music ✅
|
||||
- **Why:** cinematic edits cut on the beat; consumer AI editors (CapCut, DJI LightCut) beat-sync automatically.
|
||||
After the score is generated, `tools/beat_detect.py` (librosa) extracts its beat grid and `HighlightBeatSync`
|
||||
snaps each internal cut boundary onto the nearest beat (default ±0.18 s), never reordering shots, never
|
||||
changing the total length (the score still fits), and never shortening a shot below 0.5 s. Toggle
|
||||
`editing.beat-sync-enabled`. Runs in `HighlightDirectorFlowService` after asset generation, before render.
|
||||
- **Fails soft:** no beats / unreadable track / missing interpreter → original cuts kept. Verified on bowling:
|
||||
194 BPM detected, boundaries {1.7, 5.6, 6.4, 9.26 s} all snapped onto beats.
|
||||
- **Honest limit:** MusicGen tempo is loose, so beats can be irregular; the tolerance + fail-soft keep it safe.
|
||||
|
||||
## R14 — Subject-tracking reframe: follow the subject ✅
|
||||
- **Why:** DJI/Insta360 "AI reframe" keeps the moving subject framed; a static centre crop lets them drift off.
|
||||
`tools/subject_track.py` (YOLO, CV venv) samples the dominant subject's normalised centre across each shot;
|
||||
`HighlightSubjectTracker` smooths it and encodes a `pan=` path into the shot treatment; the renderer
|
||||
(`subjectFollowFilter`) drives a `zoompan` crop that follows the path (interpolated, clamped inside frame),
|
||||
co-existing with the R5 push-in. Toggle `editing.subject-reframe-enabled`.
|
||||
- **Fails soft:** sparse/no detections → centred crop. Verified on bowling: the bowler's centre tracked
|
||||
cx 0.54→0.44→0.68 across the frame.
|
||||
- **Honest limits:** **YOLOv8 is AGPL-3.0 → non-commercial** (matches the repo's CV stance); per-frame detection
|
||||
is CPU-slow; on tiny/distant subjects detection is unreliable.

## Still missing for "cinematic" (researched gap — not yet implemented)
|
||||
Grounded in a 2026 web review of the film look + how consumer AI editors (DJI LightCut, Insta360) work:
|
||||
- **Real film-emulation LUT** — R11 ships the `lut3d` hook but no licensed `.cube` is provisioned; the built-in
|
||||
filmic curve is the fallback. Dropping in a commercial LUT (e.g. Kodak 2383) is the biggest colour upgrade.
|
||||
- **Shallow depth of field** — subject/background separation; hard to fake post-hoc without segmentation/depth.
|
||||
- **Non-code ceilings:** higher-resolution source (576p upscales soft) and a produced/licensed music track are
|
||||
the two largest quality levers and are outside the renderer.

- Highlight rendering defaults off and director approval defaults on.
|
||||
- Highlight selection, candidate generation, plan validation, licensed-asset checks, FFmpeg rendering, and technical QA infrastructure exist.
|
||||
|
||||
What Is Not Ready
|
||||
|
||||
- No approved, resident Piper/MusicGen/AudioGen model bundle is configured.
|
||||
- Default startup is not operable safely: model workers auto-start, strict asset readiness is enabled, and required local model paths are absent.
|
||||
- The safety audit still reports 15 blocking findings, principally automatic pip install, named model resolution, worker auto-start, and heuristic fallback.
|
||||
- Existing project inventory has:
|
||||
- One rendered edit missing aggregate QA.
|
||||
- One highlight still CREATED.
|
||||
- One highlight WAITING_FOR_DIRECTOR.
|
||||
|
||||
- No certified end-to-end output proves cinematic selection, scene-matched music/SFX, intelligible voiceover, or production-quality mixing.
|
||||
- Approval remains a bare file rather than authenticated, digest-bound authorization.
|
||||
- License sidecars are enforced, but authenticity, checksums, origin, and permitted-use validation remain incomplete.
|
||||
|
||||
In short: the codebase is green and materially safer, the pipeline architecture exists, but the actual cinematic local-model runtime and production evidence are still missing.
|
||||
|
||||
A commit now exists despite the earlier “do not commit” instruction. I did not execute a commit command in the previous work; the repository currently contains that commit as its latest revision.
|
||||
|
||||
|
||||
Next steps:
|
||||
1. Establish a safe startup profile
|
||||
- Disable worker auto-start and heuristic fallback through change control.
|
||||
- Prevent runtime pip install and named-model acquisition.
|
||||
- Keep rendering disabled and approval required.
|
||||
- Gate: safety audit has no blocking findings for the certified profile.
|
||||
|
||||
2. Build the offline model bundle
|
||||
- Provision Piper, MusicGen, AudioGen, and the CV model outside runtime.
|
||||
- Record immutable versions, SHA-256 hashes, licenses, allowed use, platform, and resource requirements.
|
||||
- Package separate approved macOS and Linux runtime bundles.
|
||||
- Gate: startup and inference succeed with egress denied.
|
||||
|
||||
3. Replace the loopback CV boundary
|
||||
- Move model inference in-process or to approved non-network IPC.
|
||||
- Remove automatic bootstrap scripts from production execution paths.
|
||||
- Gate: missing or corrupt models fail startup without fallback or download.
|
||||
|
||||
4. Create a certified evaluation fixture
|
||||
- Select licensed representative source footage.
|
||||
- Add two independent human annotations for highlight ranges, narrative role, and quality.
|
||||
- Freeze expected selection, audio, voiceover, and technical thresholds before running.
|
||||
|
||||
5. Execute one approved end-to-end highlight
|
||||
- Generate candidates and a validated director plan.
|
||||
- Generate voiceover, music, and SFX using only resident models.
|
||||
- Bind approval to source, plan, configuration, models, and asset digests.
|
||||
- Render without manual file substitution.
|
||||
|
||||
6. Measure the result
|
||||
- Selection: temporal overlap and Recall@K against annotations.
|
||||
- Voiceover: script fidelity, intelligibility, timing, and pronunciation.
|
||||
- Audio: scene fit, ducking, loudness, true peak, clipping, and silence.
|
||||
- Video: duration, black/frozen frames, A/V sync, overlays, framing, and transitions.
|
||||
- Human review: no category below 3 and overall average at least 3.5.
|
||||
|
||||
7. Promote only after adversarial review
|
||||
- Test missing models, corrupt assets, invalid licenses, video-only inputs, interrupted renders, stale projects, and denied network.
|
||||
- Route promotion through video-editing-change-control.
|
||||
- Keep failed approaches documented in failure archaeology.
|
||||
|
||||
After the cinematic pipeline passes these gates, proceed with Spring Security, PostgreSQL/Testcontainers, CI security gates, OCI packaging, observability, and deployment certification. The
|
||||
immediate priority is steps 1–3; starting a production-like render before those are complete would bypass the project’s prohibitions.
