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)
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 playersscale=trunc(...)- Forces even dimensions (required by most codecs)
