I can reproduce it with current git HEAD:

------------

I've tried to use AVI as output container (instead of MOV) and it works
fine, btw.
(also playback with ffprobe (git HEAD) is working).

------------
What I found interesting is, that the initial encoding says that its
output is:
"FFV1, bgra" - which matches the input source which is rawvideo "RGBA, rgba"

But when trying to open the output video, both ffmpeg and ffprobe say
it's "ffv1, yuva444p".
