## 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.<br/>
The first command creates a palette out of the webm file. The second command converts the webm file to gif using the created palette.
