SUMMARY See Digicam tags written to videos using exiftool extension in other software (e.g. Synology Photos). STEPS TO REPRODUCE 1. Ensure that in Digicam settings metadata is being written using exiftool extension 2. Write any tag to a video file (e.g. mp4 or mov) using Digicam 8.0.0 3. Upload to synology photos and check "information" (=metadata) that is being recognized there OBSERVED RESULT The tag (in my case "Favorit") is indeed written into the video's metadata. (See below extract from exiftool.exe export). However, neither Windows File Details nor Synology Photos recognize the tag in the file. EXPECTED RESULT Since the tag is indeed written into the MP4 file, I was hoping that it is also recognized by other programs (e.g. Synology).

Well, if extra software are not able to parse XMP contents and import tags written in standard places, we cannot do anything... Gilles Caulier
I suppose tagging photos and videos is a different thing - and I know nothing about it. What I observe however is that both person/face-tags or other tags attached to videos are also not visible in a "standard" software like Windows Explorer (when viewing file details). For photos that is no problem. Is there any opportunity to write the tag somehow differently?

Windows Explorer only supports QuickTime Metadata in video files, not XMP. With the next digiKam-8.1.0 test version we will see if it works. Maik
Thx! Would this potentially cover both MOV and MP4 files?
