Generates motion graphics videos (MP4) from a content brief. Multi-scene HTML/CSS animations rendered frame-by-frame in headless Chromium via Playwright, assembled with FFmpeg. 1080×1080 default, 16:9 (1920×1080) and 9:16 (1080×1920) supported. 5 style presets. Trigger when user says "create a video", "motion graphic", "animated video", "make a reel", "create an explainer", "animated infographic", or "short video".
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# vid-motion-graphics Generates multi-scene motion graphics as MP4. Renders HTML/CSS animations in headless Chromium via Playwright (Web Animations API frame-seeking), assembles PNG frames with FFmpeg. No React, no AI APIs, no Python — zero new dependencies beyond the graphic-gif family. CDN fonts only. No external libraries in HTML. --- ## Critical Rules (read before every generation) 1. **Use `window.renderFrame(t)` — no CSS `@keyframes` for scene transitions.** CSS animation `currentTime` seeking is silently ignored for backward seeks in Chromium. The renderFrame approach: a pure JS function computes `opacity`/`transform` directly from milliseconds. Playwright calls it once per frame. Deterministic, race-free. 2. **No `animation-delay` on ANY element.** Not needed with renderFrame. If you catch yourself writing `animation-delay`, stop — you're using the wrong architecture. 3. **`window.__videoReady = true` only inside `document.fonts.ready.then(...)`.** Never set synchronously — fonts must load before Playwright captures frame 1 or text renders with fallback fonts. …

How to install
mdr add varnan-tech/opendirectory/vid-motion-graphics@sha256:63a35bd5881e23f7The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
