 ### TEMPORARY ISSUES
 1) Videos are in variable framerate format. Use MPV to play such videos, otherwise you might experience stuttering in the video if you are using a buggy video player. You can try saving the video into a .mkv file instead as some software may have better support for .mkv files (such as kdenlive). You can use the "-fm cfr" option to to use constant framerate mode.
 2) FLAC audio codec is disabled at the moment because of temporary issues.
