8## FFmpeg in Remotion
9 
10`ffmpeg` and `ffprobe` do not need to be installed. They are available via the `bunx remotion ffmpeg` and `bunx remotion ffprobe`:
11 
12```bash
13bunx remotion ffmpeg -i input.mp4 output.mp3
14bunx remotion ffprobe input.mp4
15```
16 
17### Trimming videos
18 
19You have 2 options for trimming videos:
20 
211. Use the FFmpeg command line. You MUST re-encode the video to avoid frozen frames at the start of the video.
22 
23```bash
24# Re-encodes from the exact frame
25bunx remotion ffmpeg -ss 00:00:05 -i public/input.mp4 -to 00:00:10 -c:v libx264 -c:a aac public/output.mp4
26```
27 
282. 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.
29 
30```tsx
31import { Video } from "@remotion/media";
32 
33<Video
34  src={staticFile("video.mp4")}
35  trimBefore={5 * fps}
36  trimAfter={10 * fps}
37/>;
38```
