render-photo-grid-card
Render a 'photo-grid promo card' video from a config — a real-DOM card with a FIXED header/footer and a CONTINUOUSLY SCROLLING 2-row grid of MIXED tiles (video clips, product/lifestyle stills, big-serif %-OFF, dark promo-code or CTA) + feature chips, frame-stepped via Playwright with real-time <video> playback and encoded with FFmpeg — deterministic assembly, FREE (the clips + music come from create-video-fal + create-music-elevenlabs), text stays pixel-crisp. Use for the photo-grid-promo-card format.

render-photo-grid-card
Render the 'photo-grid promo card' format from a config. The signature of this format is a continuously scrolling 2-row grid (NOT a static card) under a fixed header (brand wordmark + big headline + sub) and fixed feature chips. The grid-viewport scrolls left across the whole ~10s, edge-faded with a CSS mask, and its tiles are mixed media: video clips playing inside tiles, band-product/photo stills, big-serif pct/off type tiles, and a dark code (promo code) or cta tile.
The renderer itself is FREE/deterministic (Playwright frame-step + FFmpeg). The paid inputs are separate capabilities: the tile clips come from create-video-fal (i2v of the product heroes, or clips extracted from the brand's own ad corpus) and the music from create-music-elevenlabs. Text (wordmark, %, code) is real DOM — never AI-rendered.
Run
build_card.py --config config.json --out hyperframe.html ; render.py --config config.json --html hyperframe.html --out master-silent.mp4 — 1080x1920, scrolling grid, deterministic, $0.
Clip tiles are driven by FRAME-SWAP, not <video>: render.py pre-extracts each clip to PNG frames with ffmpeg, preloads them, and swaps each <img class="vidframe">'s src per output frame. This is because Playwright's bundled Chromium can't decode <video> H.264 over file:// (open-source build, no proprietary codecs) — it hangs on canplay. Letting ffmpeg decode makes it codec-independent AND deterministic. Provide clips longer than the master (or the swap just loops them); a subtle setpts-slow reads as cinematic.
Contract
- Deterministic + FREE (Playwright frame-step + FFmpeg); no paid calls in this capability.
- Tiles-per-row = grid columns (
cols), NOT total tiles; the grid fills row-major. - The template recipe (DB) supplies the config; clips + music are separate capabilities.
