# Random Data Visualisation stuff

This is just some random stuff I wanted to put somewhere since I spent time figuring it out.

## Convert `mov` to `mp4` trivially.

```shell
ffmpeg -i input.mov -c:v copy -c:a copy output.mp4
```

## convert movie clip to animated gif

From [blog post](https://dev.to/nabbisen/ffmpeg-convert-video-to-gif-7h8). [Original documentation](https://ffmpeg.org/ffmpeg-all.html#Video-Options)

```shell
START="01:13:22"
SECONDS="8"
FPS=10
INFILE="input.mp4"
OUTFILE="output.gif"
ffmpeg -ss $START -t $SECONDS -i "${INFILE}" -r $FPS "${OUTFILE}"
```
