There isn't much built-in support for editing .MOV metadata, I think due to our metadata library not knowing about the format.
You should be able to display at least some metadata in columns, although I don't have any tagged .MOV files to test with and Windows seems to only have read-only support for .MOV so I can't easily tag the files I have to try them. AFAIK it should work, though.
If none of the built-in columns show what you need, you may find a suitable column under Preferences / File Display Columns / Shell Properties which you can turn on in Opus. That lists File Explorer's columns and lets you use them within Opus.
If you want to use ExifTool to display information in columns:
There's also MediaInfo:
- MediaInfo++:All the MediaInfo data you can ask for!
- MediaInfo-based extended columns & commands v0.9, released on GitHub
(Opus also uses MediaInfo for read-only metadata, but those let you add more columns than the ones that are built-in.)
I'm not sure what the best way to edit MOV metadata is, although ExifTool can probably be used to do that as well.
