[chimerax-users] Transparent background movie

[Tom Goddard]

Are there any video codecs that support transparency?  It looks like few people have achieved this online and only with exotic formats.  For example,

ChimeraX uses ffmpeg to encode videos.  It first saves image files for every frame and it would be possible to save those with transparency.  But you'd have to make a good case that that has some value for us to add the option to the movie command.
