As per this discussion we have updated the Animator to match the encodings used in Screen Capture module. However, this resulted in a repeatable error in ffmpeg encoding (see video below). Same happens in Screen Capture when the number of images are set to maximum.

Curiously this only happens on windows, mac’s doesn’t seem to be affected.

ffmpeg standard output:
