FFmpeg in Remotion

ffmpeg and ffprobe do not need to be installed. They are available via the npx remotion ffmpeg and npx remotion ffprobe:

bash
npx remotion ffmpeg -i input.mp4 output.mp3npx remotion ffprobe input.mp4

Trimming videos

You have 2 options for trimming videos:

  1. Preferred: Use the trimBefore and durationInFrames props of the <Video> component. This is non-destructive, requires no re-encoding, and you can change the trim at any time.
tsx
import {Video} from '@remotion/media';
<Video  src={staticFile('video.mp4')}  trimBefore={5 * fps}  durationInFrames={5 * fps}/>;
  1. Use the FFmpeg command line. You MUST re-encode the video to avoid frozen frames at the start of the video. Only use this if you need a standalone trimmed file (e.g. for upload or external use).
bash
# Re-encodes from the exact framenpx remotion ffmpeg -ss 00:00:05 -i public/input.mp4 -to 00:00:10 -c:v libx264 -c:a aac public/output.mp4
