Thanks gentlemen. Also in case it helps anybody else I figured out a way to do this in Metadata Hootenanny with the already exported files since I have 150 of them. It’s a bit lengthy bc it covers two scenarios so here goes:
IF WORKING WITH MOVs:
Note: make a backup of all files first or test on a small group.
Open MOVs in Metadata Hootenanny:
Select all files in Main View (⌘\)
Change to Metadata and Info (⌘I)
Modify all info as needed
Save (⌘S)
Select all edited movies
Set destination for outputting new files.
Do one of the following:
‘Self Contained’ will create new copies (takes longer than ‘Save in Place’)
‘As Reference Movie’ don’t use this option. It creates alias-like files.
‘Save in Place’ will modify original files so make a backup if choosing this option.
IF WORKING WITH M4V (probably applies to MP4s or other file types as well):
Note: make a backup of all files first or test on a small group.
Open M4Vs in Metadata Hootenanny:
Select all files in Main View (⌘\)
Change to Metadata and Info (⌘I)
Modify all info as needed
Save (⌘S)
Select all edited movies
Set destination for outputting new files.
Choose Self Contained. This will create new copies and takes longer than ‘Save in Place’. This also changes file extension to MOV.
Note: Save in Place does not support M4Vs.
Change extension back to “.m4v”
Thanks.
