render-value-prop
Render a designed 'value prop' video from a config — 3-5 noun-phrase benefit claims (<=4 words each) revealed sequentially over per-SKU product visuals, one crisp editorial frame per claim (hook sticker -> N claim beats -> brand end card). Deterministic PIL/HTML beat renderer frame-stepped via Playwright and encoded with FFmpeg, sound-off legible, hard cuts, uniform pacing. FREE (no paid calls); music is added separately (create-music-elevenlabs). Use for the value-prop format.

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.
Contract
- Deterministic + FREE (Playwright frame-step + FFmpeg); no paid calls, no AI-rendered text.
- Claims are noun phrases, <=4 words; never <3, never >5. Optional benefit sentence <=12 words.
- One product visual per beat; rotate which SKU is the hero. Never reuse a flat variety-pack image as every canvas.
- Sound-off legibility is the bar: the headline uses the config
palette.inkcolor onpalette.bg; the per-beat accent color (fromvalue_props[].accent— a SKU-accent slug or a hex) is the accent rule, not the headline. - Product widths auto-scale from each image's aspect ratio (target display height), so tall sachet cutouts and wide product packshots both frame correctly.
- Assets are packshots, not always transparent cutouts: set
palette.bgto the product image's background color for seamless compositing (free — avoids a paid background-removal step). - Uniform pacing (hook ~3.0s, props 2.0-2.5s each, endcard ~2.0s); total lands in the 10-20s window (~17s). No acceleration curve.
- No human face is the focus. End card uses the brand wordmark image when a hi-res one (aspect >= ~1.2, i.e. a real >=1200x600 wordmark) is provided via
config.logo; otherwise it falls back to a typographicbrand_namewordmark (many brands ship only a favicon). - Music is added separately by create-music-elevenlabs (quiet instrumental bed at -14 dB), or ship silent.
