I'm using ExifTool to read information from video files and ran into a file that has different values in some of those tags.
I have two questions:
1) What is the difference between the above 3 tags? Or, actually, between all six (those and their group 1 counterparts)?
2) What is the difference between 'MediaDuration' and 'MediaDuration (1)'? I understand that tags with '(1)' are from group 1, but I'm unclear what the distinction between Group 1 and non-Group 1 tags.
Thanks, Amir
