Video and audio processing with FFmpeg. Use for format conversion, resizing, compression, audio extraction, and preparing assets for Remotion. Triggers include converting GIF to MP4, resizing video, extracting audio, compressing files, or any media transformation task.
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
# FFmpeg for Video Production FFmpeg is the essential tool for video/audio processing. This skill covers common operations for Remotion video projects. ## Quick Reference ### GIF to MP4 (Remotion-compatible) ```bash ffmpeg -i input.gif -movflags faststart -pix_fmt yuv420p \ -vf "scale=trunc(iw/2)*2:trunc(ih/2)*2" output.mp4 ``` **Why these flags:** - `-movflags faststart` - Moves metadata to start for web streaming - `-pix_fmt yuv420p` - Ensures compatibility with most players - `scale=trunc(...)` - Forces even dimensions (required by most codecs) ### Resize Video ```bash # To 1920x1080 (maintain aspect ratio, add black bars) ffmpeg -i input.mp4 -vf "scale=1920:1080:force_original_aspect_ratio=decrease,pad=1920:1080:(ow-iw)/2:(oh-ih)/2" output.mp4 # To 1920x1080 (crop to fill) ffmpeg -i input.mp4 -vf "scale=1920:1080:force_original_aspect_ratio=increase,crop=1920:1080" output.mp4 # Scale to width, auto height ffmpeg -i input.mp4 -vf "scale=1280:-2" output.mp4 ``` ### Compress Video ```bash # Good quality, smaller file (CRF 23 is default, lower = better quality) ffmpeg -i input.mp4 -c:v libx264 -crf 23 -preset medium -c:a aac -b:a 128k output.mp4 …

How to install
mdr add digitalsamba/claude-code-video-toolkit/ffmpeg@sha256:20a0c1e35a683a6bThe line at the top of this page pins the label git:20260126.efc2cb2, 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.
