Is there a way to simply view the date on which a video was taken? Somehow, saving it to iPhoto or the cloud seems to change the create date to the upload/download date?? And so I don't even use iPhoto any more. But that doesn't help me with the videos I shot four or five years ago. Any help? Thanks!
Excellent

Sadly, this works only with MKV containers of MP4 files. It would be nice to have a tool that works with stand-alone MP4 files.
