GraphicConverter "Execute custom ExifTool Command"
I almost always use GraphicConverter to check and edit image and movie metadata instead launching exiftool via the Terminal to do the same task.
But GC menu items can't cover ALL possible and esoteric metadata tasks.
GraphicConverter 12.5.2 added command "Exif Metadata > Execute custom ExifTool Command..." so you have best of both worlds (only direct calls to exiftool. No piping, grep etc, though).
Use or fine-tune example commands or write your own command to a text file in '~/Library/Application Support/GraphicConverter/ExifTool'.
Select desired images or movies in GC Browser. Leave 'exiftool' off from the usual Terminal command and use '@filepath' as filename as follows:
-a -G1 -s -api QuickTimeUTC=1 -FileCreateDate -FileModifyDate -DateTimeOriginal -OffsetTime* -QuickTime:CreateDate -Keys:CreationDate @filepath
...so the same Terminal command is as follows. '-fileOrder5 FileName' keeps APFS filesystem output in alphabetical order (GC Browser takes care of sorting). Terminal might need * wildcard and characters like $, filename spaces etc to be quoted as follows:
exiftool -a -G1 -s -fileOrder5 FileName -api QuickTimeUTC=1 -FileCreateDate -FileModifyDate -DateTimeOriginal '-OffsetTime*' -QuickTime:CreateDate -Keys:CreationDate .
But make a backup before any write commands until you are sure your workflow works as desired.
