# ffmpeg

## TL;DR

```sh
# Convert a webm file to GIF.
ffmpeg -y -i rec.webm -vf palettegen palette.png \
  && ffmpeg -y -i rec.webm -i palette.png \
       -filter_complex paletteuse -r 10 out.gif
```

## Format conversion

### Webm to GIF

```sh
ffmpeg -y -i rec.webm -vf palettegen palette.png
ffmpeg -y -i rec.webm -i palette.png -filter_complex paletteuse -r 10 out.gif
```

Here `rec.webm` is the recorded video.  
The first command creates a palette out of the webm file. The second command converts the webm file to gif using the created palette.
