Copy video create date from original file

This is the companion script for: Video re-encode script

It uses exiftool to copy the video date atom(s) and setfile (is or was included with Apple’s Developer Tools) to change the file system dates. It will more than likely throw exiftool “File not found” errors and I’m not quite sure why. It has never failed to actually work despite this in my experience, however be very careful to not use this on your original source videos.

Hopefully the settings and prompts make sense.

This uses Apple's command line developer tools command 'setfile' to set the filesytem dates.

I believe an Apple Developer account is required for that, but I am not sure.

Uses 'exiftool' to set track date atoms.
