I just tried to attach a small video to a comment and couldn’t because apparently only image formats are allowed.
A quote from How can I embed videos hosted on our site? - #9 by awesomerobot - feature - Discourse Meta
If the filetype is enabled in your settings, videos can be posted directly as you would with images. The full video isn’t loaded for the user until it’s played.
Can we enable videos as well? It especially makes sense for animations since GIF files sometimes tend to take an enormous amount of space compared to e.g. MP4 with h264 codec.
