I can't write "-exif:OffsetTimeOriginal" to a MOV-file.

I need to fully fill video files with metadata, so I'm looking for a list of standard metadata tags for video. If I understood correctly, reading the standards with a translator, then IPTC Video Metadata Hub positions itself as a replacement for all metadata standards for video. I assumed that I could have misunderstood something and therefore wanted to find confirmation of my assumptions on the forum. After all, ExifTool is made according to standards and I was sure that here know about the PTHC Video Metadata Hub.
Are you not familiar with this standard?

The IPTC video metadata standard is relatively new.  It uses XMP in videos which isn't widely supported by other applications yet.  However, ExifTool fully supports this standard.
