Transparent PNG and SVG snapshots are good and all, but being able to capture MP4 animations with sound and APNG movies would be absolutely next level.

WebM (VP8 and VP9), MOV/QuickTime (HEVC, Apple ProRes 444), FLV, and AVI supposedly support transparency, might be worth using those formats and not touching APNG at all, or keep that as optional/experimental format.
