Produces short captioned motion explainers by streaming Pillow frames into FFmpeg and verifying the finished MP4. Use when asked for an animated explainer, narrated process video, or reproducible lightweight motion graphics without browser or scene-engine dependencies.
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
# Narrated motion explainers ## Deliver a video, not merely a renderer 1. Establish audience, one message, runtime cap, aspect ratio, and narration rights. Write a fresh brief and short chapter script; retain source notes for factual claims without copying full source pages. 2. For narration, obtain an authorized local recording or optional TTS output. Measure audio with ffprobe before setting chapter durations. Do not invent speech timing from word counts. Keep any external TTS provider optional; never bundle credentials. Match captions to actual speech, restoring punctuation only after token alignment and clamping overlapping cues. 3. Render a short preview first. Use deterministic scene state at time `t`, RGB Pillow frames, and FFmpeg rawvideo input. Animate the explanatory subject, not only the background or caption strip. Use legible captions, bounded text, and licensed fonts; avoid distributing font binaries without permission. 4. Encode H.264/yuv420p plus AAC at an explicit 48 kHz sample rate. Bound output duration and processing time. Preserve chapter JSON, captions, renderer and audio beside the MP4 so visual rerenders do not require network access. …

How to install
mdr add suryast/free-ai-agent-skills/narrated-motion-explainers@sha256:565ac75d38cccd04The line at the top of this page pins the label git:20261010.461cc7c, 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.
