Remotion is now the default composition engine for ALL final renders
when available — video clips, images, mixed content. FFmpeg is only
used as fallback when Remotion is not installed or for standalone
operations (trim, transcode). Also fixes three FFmpeg fallback bugs:
profile + copy codec conflict, stream order mapping, and segment
seeking for audio-first containers.
Four gaps found during user acceptance testing of the reference-video
production workflow:
- video_selector: expose aspect_ratio, duration, reference_image_path,
reference_image_url, and image_url in schema so agents can discover
these critical params. Auto-upload local images when the selected
provider requires a URL.
- _shared.py: add upload_image_fal() for local→URL image bridging via
fal.ai storage. Fix upload_image_heygen() to try v2 presigned upload
before falling back to fal.ai (old /v1/asset endpoint returns 404).
- kling_video: call probe_output() so response includes output_path,
duration_seconds, file_size_mb, video dimensions, and codec info.
Implements the 2026-04-02 transformation spec (Phases 1-8) and fixes all
critical bugs found during 5-pipeline E2E testing.
Governance & Decision Intelligence:
- Pipeline-specific stage order in checkpoint (replaces global STAGES list)
- Provider scoring engine (lib/scoring.py) with 7-dimension weighted ranking
- Decision log artifact enforced at proposal/idea stage across all 10 pipelines
- Delivery promise classifier prevents silent motion-to-still downgrades
- Structured shot language in scene_plan schema (camera, lens, lighting, DOF)
- Variation checker and slideshow risk scorer block samey output before render
- Creative intake, capability extension, and creative-intake meta skills
- Final self-review artifact with 5 mandatory checks before presenting output
- Source media review contract for user-supplied footage
Render & Theme System:
- Remotion AnimatedBackground now derives colors from playbook (no more hardcoded
dark blue fintech gradient on every video)
- video_compose builds custom ThemeConfig from playbook YAML colors/fonts —
custom playbooks flow through to Remotion automatically
- Explainer component wires theme to all child components (charts, cards, etc.)
- resolveAsset() handles absolute paths on Windows/Unix via file:// URIs
- RENDERER_FAMILY_MAP synced with actual Remotion compositions
Critical Bug Fixes:
- Windows npx subprocess: run_command() resolves .cmd wrappers via shutil.which()
- Silent renderer downgrade: Remotion failure now returns explicit error with
options instead of silently falling back to FFmpeg
- .env inline comment parsing strips trailing # comments from API keys
- concat_path UnboundLocalError in video_compose finally block
- audio_mixer and showcase_card capture=True kwarg bug
- Selector estimate_cost() calls fixed (_select_tool -> _select_best_tool)
- asset_manifest schema expanded with provider, license, subtype fields
- screen-demo subtitle_gen moved from required to optional tools
- Duration drift detection in post-render final review (>25% warns)
Add green_screen_processor (auto-detect + rembg fallback) and
green_screen_composite (4 layout presets with alpha compositing) tools
to automate the full keying-to-composite pipeline.
Remotion: add AnimatedBackground with gradient mesh and floating orbs
to Explainer, fix caption burn tool (remove entry point arg, auto-detect
dimensions, extend TalkingHead duration to 300s).
Update scene-director, compose-director, and asset-director skill docs
with green screen workflow steps and component constraints.
Scene-director rewrite: agent now watches footage, understands content, and proposes
creative overlays (charts, stats, key terms, comparisons) before building anything.
Presents enhancement plan to user for approval before proceeding.
Compose-director fixes from Round 1 verification:
- eye_enhance: now explicitly required, not silently skippable
- Caption positioning: explicit MarginV=160 for 9:16, never center
- Final encode: mandatory with target file size table
- ASR corrections: new Step 2b to scan transcript and build corrections dict
- Overlay compositing: new Step 3b for burning approved graphics onto footage
Asset-director rewrite: generates Remotion overlay assets (callouts, stat cards,
charts, comparisons) from scene plan. Includes overlay type → Remotion cut mapping
table and dark theme requirements.
Bug fixes found during subagent verification:
- remotion_caption_burn.py: fix run_command API, add npx.cmd for Windows
- visual_qa.py: fix run_command API (3 places), Windows /dev/null → NUL
New tools: face_tracker, visual_qa, eye_enhance, auto_reframe, remotion_caption_burn, showcase_card, silence_cutter. Updated audio_mixer with segmented_music operation and subtitle_gen with ASR corrections. Registered TalkingHead composition in Root.tsx. Rewrote compose/edit/scene director skills for full enhancement chain, Remotion captions, multi-clip assembly, and visual QA. Gitignore cleanup: exclude test demo-props, downloaded music, and generated images.
- Fix Kling URL format: text_to_video → text-to-video (hyphens)
- Fix Kling, MiniMax, Veo: switch from sync fal.run to queue API with polling
- Add Rule Zero to AGENT_GUIDE: all production must go through pipelines
- Make Layer 3 skill reading mandatory before calling generation tools
- Add explicit do-nots: no ad-hoc scripts, no skipping director skills
