Looking a bit at this (as exiftool is not really relevant for Digikam) I found this: http:// (about 5 years old). Looks like video metadata is even more of a 
mess than the photo metadata ('makernote'...).
And that project only used video directly from camera's (so no transcoding to other formats/

Also, do you really want to write into (possibly unique) video files (eq. to photo RAW images), 
or could a sidecar XMP do the trick? I guess that comes down to asking how often you use 
those metadata *outside* of digikam.
