Most likely inputs have not same number of frames.
They don't have the same number of frames. That's why I need to specify
the duration, either with "-t 00:01:00" or with "-frames:v 3596". The
correct number of frames *is* 3596, however, so I don't understand why
I have to limit the comparison to only 3595 frames to get the correct
result.
