Hey @danielabc
I’m not completely sure about the details of this problem. When I
- right click one of the images above
- click “copy image”
- Paste it into the editor I get:

Which looks like this in the editor

How are your users copying and pasting their gifs?
I expect this is currently not possible, and unlikely to be possible in the future. Gif and mp4 are two different things.
- .mp4 is considered to be a video type, just like .webm, .mpeg, .ogg
- This means discourse will deliver anything with this file-type as a video, in a video window
- .gif is an “animated sequence of images”. Yes, that’s pretty much what a video is, gif is just a very specific way of delivering that content.
- Consequently .gif will not use a video player.
This is pretty much standard. Upload a file as a gif, it will act like a gif. Upload a file as a video format, it will act like a video.
