Invalid File Format error during -filemodifydate=${directory} -ext mov

[SampsonF]

When I am trying to update the FileModifyDate for MOV/mov files, exiftool give error for some of the MOV files.

I do not keep a log of the process, now how can I find out those MOV files having invalid formats from those good files?
(I want to move those invalid files into a separate folder for further inspection one by one.)

Thanks in advance!

You could try this:

exiftool -validate DIR
