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 players

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