Devlog 8 - Adding Gif to the video format.

I thought it would be easier but I spent 2 hours of finding a good way to convert Gif to video format (such as MP4). I started with a librarie but I had an error, so I switched for FFmpeg and this has led to a lot of bugs. I coorected them and added a better preview of what your video would like.
Now everything works well so try it by converting your best meme.
