Generate content identifier tag for live photos

[StarGeek]

I just copy/pasted what Phil posted into a file and I was able to write that tag.

Code Select Expand

C:\>exiftool -config temp.config -P -overwrite_original -keys:ContentIdentifier=test y:/!temp/Test6.mp4
    1 image files updated

C:\>exiftool -G1 -a -s -keys:all y:/!temp/Test6.mp4
[Keys]          ContentIdentifier               : test
Try using the -Config option to explicitly used your config file.

exiftool -config C:\Windows\.ExifTool_config -keys:ContentIdentifier=test /path/to/files/

You're right! I just used the same command you posted and it worked. I had a redundant Quicktime parameter before Keys. Can't believe it took me this long haha!

Thank you so much Phil and Stargeek!
