[Chimera-users] Creating movies with alpha channel / transparent background

You can have Chimera save a series of transparent background images using the movie command, for example,
movie record dir ~/Desktop/test format png ; turn y 1 90 ; wait 90 ; movie stop
Then you would need to encode the PNG images in ~/Desktop/test into a movie using some encoding program. I doubt the Chimera "movie encode" command supports any video format that can handle transparent background. Chimera uses ffmpeg to encode movies and apparently ffmpeg can encode some video formats with transparency, for example, as described here the motion PNG format in .mov can handle transparency
