Grab ffmpeg from https://www.ffmpeg.org/download.html It's a command line tool which means you will have to type things with your keyboard instead of clicking on buttons. The most trivial operation would be converting gifs: ffmpeg -i your_gif.gif -c:v libvpx -crf 12 -b:v 500K output.webm -crf values can go from 4 to 63. Lower values mean better quality. -b:v is the maximum allowed bitrate. Higher means better quality. To convert a part of a video file: ffmpeg -i your_video.mkv -ss 00:00:10.000 -to 00:00:20.000 -c:v libvpx -crf 4 -b:v 1500K -vf scale=640:-1 -an output.webm -ss is the start position in number of seconds, or in hh:mm:ss[.xxx] format. You can get it using your video player (Ctrl-G in MPC-HC). -to is the end position. -vf scale=640:-1 sets the width to 640px. The height will be calculated automatically according to the aspect ratio of the input. -an disables audio.
