You have 2 options for trimming videos:

Use the FFmpeg command line. You MUST re-encode the video to avoid frozen frames at the start of the video.

# Re-encodes from the exact frame
bunx remotion ffmpeg -ss 00:00:05 -i public/input.mp4 -to 00:00:10 -c:v libx264 -c:a aac public/output.mp4

Use the trimBefore and trimAfter props of the <Video> component. The benefit is that this is non-destructive and you can change the trim at any time.

import { Video } from "@remotion/media";

<Video
  src={staticFile("video.mp4")}
  trimBefore={5 * fps}
  trimAfter={10 * fps}
