## 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.
|
|
|
|
### WebM to MP4
|
|
|
|
```sh
|
|
ffmpeg -i 'input.webm' -c 'copy' 'output.mp4'
|
|
ffmpeg -fflags '+genpts' -r '24' -i 'input.webm' 'output.mp4'
|
|
```
