Exif Video data, cant write when null

[Fraser]

Need my batch file which uses the Exiftool.exe to write to the windows tags in exif its called -Category this works but when the video has no tags already it does nothing says updated but nothing has changed, using /GD -a -s filepath tell me that it is there but when i look in details tab of video its not there and not organised in file explorer view.

What is the exact command you are using?

By default, exiftool will write the ItemList:Category in a video file. But if you look at the Windows Metadata post, you will see that Windows instead reads the Microsoft only Microsoft:Category tag to fill the "Tags" property. You will have to tell exiftool to write that specifically.

exiftool -Microsoft:Category=DATA /path/to/files/
