Same happened to me..i had to manually download the video and move it to the asset/mp4 directory...if you're gonna do the same don't forget to rename the mp4 file to background.mp4

Seems to be working to some extent for me, it passes the downloading and merging phase, but then hangs up again with moviepy.

Deleting original file assets/mp4/background.f308.webm (pass -k to keep)
