Description malte.boensch 2023-03-12 09:47:29 UTC 
SUMMARY
I use digikam 7.9.0 to write tags to both photos and videos to be able to filter based on tags on other platforms (e.g. Synology Photos). Tag-writing for pictures is not a problem. Synology recognizes all tags that I added to a photo with digikam.
However for videos (mp4 & mov) this is not the case. When I add a tag to a video file in Digikam it shows in the Album/Thumbnail view that the tag was added, however, the tag does not seem to be written to the file.
Neither irfanview, Windows Explorer (File Details) or Synology recognize the tag I added

STEPS TO REPRODUCE
1. Add any tag to a video file (mp4 or mov) in Digikam
2. View the file properties in an external program (e.g. irfanview or Windows Explorer file details)
3. The tag does not appear to be added to the file although it shows in Digikam.

OBSERVED RESULT
The tag does not appear to be added to the file although it shows in Digikam.

EXPECTED RESULT
Tag should be visible in the file and should be recognized by other software.

Thank you for the quick response. 
Is an approximate release date for 8.0 forseeable?
Comment 3 Maik Qualmann 2023-03-12 10:09:10 UTC 
An exact release date has not yet been decided. You can download the current version from here:

Note that you should back up your digiKam database in case you want to revert to an older version.
