| description | 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.ink color on palette.bg;
the per-beat accent color (from value_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.bg to 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 typographic brand_name wordmark (many brands ship only a favicon).
- Music is added separately by create-music-elevenlabs (quiet instrumental bed at -14 dB), or ship silent.
