Expected Results:  
The geolocation metadata is added to the file

Hi,

the problem here is that we do not currently support writing metadata into movie files. The coordinates are saved in the database, however. In previous pre-2.0 versions, no metadata was written to movie files, either, but there was no warning.

For now, you can use sidecar files instead of storing the metadata in the movie files directly, but there were recently some bugs reported about correct handling of coordinates in sidecar files, like bug#280058.

Regards,

Michael

Video file metadata is currently implemented in Exiv2 library used by digiKam in background.

Also Micheal comment about to use XMP sidecar is the only way to work with Video metadata in writing mode.

There is nothing to do to improve this state in digiKam implementation. All future improvements must be done in Exiv2 shared lib.
