Hey @xeoncross , can you fetch the latest version from the master branch and try again? It will fail again but with some more output that should help to understand why this happens.

Note that the changes that the script does to the video file are not in any way guaranteed to help, it's a poor-man's attempt to fixing the metadata in the file. It's likely that it's not going to work for your broken video file.

Thanks, I tried again and this is the new output

Woops, I made a mistake in the code (didn't have a MOV file at hand so I winged it). Can you please try again?
