[FFmpeg-user] Fastest way to check integrity of video files

[Molly Millions]

Thanks for the replies so far!

I have a lot of videos in lossless mov. I convert these to mp4. So, after a
mov -> mp4 conversion is done, I'd like to check the output the fastest way
possible for errors. I need these, because the environment I'm working in
has some strange storage anomalies, which I'd like to nail down and also be
sure, that the result is correct and not plagued by errors.
