render-value-prop

Render a designed 'value prop' video from a config: a hook sticker, then one beat per short noun-phrase benefit claim (<=4 words each — "Drug-Free", "Zero Sugar", "NSF Certified"), each pairing the claim headline with a per-SKU product visual (the hero SKU rotates beat to beat so the eye anchor shifts), then a brand-wordmark end card. Text + product carry the spot — no narration, no talking head — and it is built to be legible sound-off. Every beat is a pure function of beat-local time t (deterministic PIL start frames + Playwright hyperframes + FFmpeg); no CSS keyframes, no setTimeout. FREE (no paid calls); music is a separate capability (create-music-elevenlabs), or ship silent for $0.

Run

render_master.py --config config.json --project <dir> -> <dir>/finals/master-clean.mp4 (silent), 1080x1920, deterministic, $0. The renderer is fully config-driven — palette, copy, SKUs, pacing, hook, logo and end card all come from config.json (schema = ad_sample.recipe.config; see config.example.json). Nothing is hardcoded to one brand. build_storyboard_preview.py is an optional free preview gallery for the gate; build_text_overlays.py is optional (transparent text-zone PNGs for compositing claims over a motion clip).

Environment: run with a Python that has Playwright (override the frame-render interpreter with RENDER_PYTHON); ffmpeg is auto-discovered (FFMPEG env > PATH > common prefixes). The frame renderer render_hyperframe.py is bundled in scripts/ — no external atom to fetch.
