Chimera uses ffmpeg to encode movie files.  Searching online, it appears 
that ffmpeg supports .png files for output, which are APNG files.  So it 
should possible to add that as an output format. Currently, we are only 
making bug fixes for Chimera, so if we add this feature, it would be for 
ChimeraX.  That said, the movie encoding support code in ChimeraX is 
very similar to Chimera's. So it looks like it would be easy to 
backport.  I'll create a ChimeraX ticket on your behalf so you'll be 
notified when it is added to ChimeraX.
