Batch Convert .webm to .jpg (Single and Multiple)

To batch convert webm's to JPG in a folder with FFMPEG, open Terminal and navigate to the folder containing the webm files. Then, run the following command:

```
for x in ls *.webp; do  ffmpeg -i $x ${x%.webp}.jpg; done

This will convert each webm file in the folder to a JPG file with the same name.

To convert a single webm file to a JPG file with FFMPEG, run the following command in Terminal:

```
ffmpeg -i input.webm output.jpg
```

Replace "input.webm" with the name of your webm file, and "output.jpg" with the name you want to give the resulting JPG file.
