SUMMARY When selecting a video file (mp4, or mov) keywords are not showing applied to the file. Other applications see keywords just fine (Lightroom, ACDSee) and can see the keywords just using a Metadata viewer. STEPS TO REPRODUCE 1. Have video with keyword applied. 2. Import Video into digikam 3. View Metadata to video in digikam OBSERVED RESULT No keywords are shown and filtering by keyword doesn't work EXPECTED RESULT Keywords are shown, and filtering by keyword works SOFTWARE/OS VERSIONS Windows: 10 ADDITIONAL INFORMATION
What do you mean exactly ? You want to save in video file metadata the DK keywords as well ? If yes DK is not able to do it through ffmpeg. It can do it only with Exiv2 inside an XMP sidecar. For digiKam, video file are read only, this is why we need to pass by an XMP side car for the video metadat update. Gilles Caulier

Currently none of my video files appear to have keywords, even though they all have them embedded from Lightroom and a Metadata viewer shows them.
If Lightroom or ACDSee do not generate XMP sidecar to store keywords or do not store keywords as well in MP4 file metadata, digiKam will not able to process a complete import of file properties. In others words, digiKam is not able to backport properties from proprietary photo management database. You need to setup your application to store keyword in one of this way for interoperability reason. If you provide a MP4 file sample already tagged with you application, we can take a look if keywords are stored inside. Best Gilles Caulier
After some more digging, you are correct. I thought Lightroom had written metadata into the videos, but it is stuck in it's database and refused to generate sidecar xmp files. Thus DK is correct, sorry for the confusion.
