# FFmpeg Recipes

### Remove audio from video

```bash

$ ffmpeg -i [input file] -vcodec copy -an [output file]

```

### Extract part of a video

This will cut 5 seconds starting at 00:30 from the original video:

```bash

$ ffmpeg -i [input file] -ss 00:00:30 -t 00:00:05 -vcodec copy -acodec copy \

    -movflags faststart [output file]

```

### Convert a video to GIF

Ffmpeg 2.0 has improved support for GIFs. To convert a .mp4 to a .gif:

```bash

$ ffmpeg -i [input file] -vf scale=320:-1 -t 10 -r 10 output.gif

```

Where `-t 10` limits the output to 10 seconds. `-r 10` forces a frame rate of 10 fps.

The `scale=320:-1` is to set the width and height, here we pass -1 so ffmpeg picks the

best height for us.

### Convert MP4 to WebM

To convert you need to install ffmpeg with support for these codecs

On OSX:

```bash

$ brew install ffmpeg --with-libvpx --with-libvorbis

```

then you can use `libvorbis` and `libvpx` to convert your mp4 to webm:

```bash

$ ffmpeg -i [input file] -acodec libvorbis -vcodec libvpx [output file]

```
