With Exiv2 it is not possible to change the metadata in video files or it is very unstable and can lead to data loss or crashes. Therefore digiKam-7.x.x is only possible to work with the help of XMP sidecar. In digiKam-8.0.0 it is possible to use ExifTool to write metadata, then supported video files can also be modified. Maik

Not all time metadata can be set without problems. It needs more tests. Maik

Hi Maik, Thanks for picking this up. As for testing, let me know if I can assist. Meanwhile (as a datapoint) I found a sort of work around: If I tick only the "File Last Updated" timestamp to be updated, it works. This timestamp is correctly updated and the video moves to the right position in my timeline. Bert
