The version currently in main uses FFMPEG, so it's expected to be available on path. That said I'm switching method in #50 to avoid the need for ffmpeg!
It should be in the release tonight

Thank you… I fixed the issue by making sure FFmpeg was in the system path. It now works perfect.

Nice, the reason for the switch from ffmpeg is mostly size and quality, results look better using PIL only
