I produce high quality Animated PNG files and it takes a lot of juggling different computers to accomplish.
Is there a way to simply chose APNG from the movie recorder output pulldown menue?
Would there be a plug in for that?

My animations can be found at:

Thank you

ChimeraX and Chimera have very similar code for supporting movie formats. So after adding the format to ChimeraX, consider backporting ti to Chimera.

Well, this was easier than I thought. So it will be in the next day's ChimeraX and Chimera daily builds. The format name is "APNG" and the file suffix is ".png". The quality, qscale, and bitrate arguments should have no effect.
