How do I change all GPS fields for .mp4 files

[Maik Qualmann]

Hi,

Video files cannot be compared with images. What digiKam shows in the Exif or 
XMP metadata tabs for videos is "virtual". We can currently only write GPS 
coordinates in XMP (or Exif for images). Depending on the type, video files can 
also contain a QuickTime container that contains GPS metadata.
The same problem exists with date and time; in digiKam-8.4.0 we have created a 
way to change "all" dates in the Time Adjust Tool using ExifTool, including in 
the QuickTime container. We would also have to add something similar for GPS.
