Hand-author an HTML composition and render it to a deterministic MP4 explainer video by seeking a paused GSAP timeline frame-by-frame with headless Chromium and FFmpeg, fully offline with locally vendored assets.
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
# Skill: Explainer Video (HTML to MP4) Render a short animated explainer video from a single hand-authored HTML file. The capability: a renderer drives a paused GSAP timeline frame-by-frame in headless Chromium and pipes each frame to FFmpeg, producing an MP4. There is no build step and no proprietary timeline format — the HTML plays as-is. This skill uses [HyperFrames](https://github.com/heygen-com/hyperframes) (Apache-2.0) as the reference renderer, but the technique generalizes to any tool that seeks a deterministic timeline. The render runs entirely offline with locally vendored scripts and fonts. This skill produces a draft video for human review, never a publish-ready artifact. ## When to Use - Building a short animated explainer (title cards, timed reveals, simple charts) - Producing a launch or promo video for a release - Turning a static one-pager into a 30-45 second animated overview - User asks "make an explainer video", "html to video", or "animated overview" ## When Not to Use - The content contains secrets, real PII, or real CUI (never send to a renderer you do not fully control; never use hosted rendering) …

How to install
mdr add gsa-tts/agentic-coding-patterns/explainer-video@sha256:99df7111497ed21dThe 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.
