Perhaps this is not the right place to ask since it's only partially related to DigiKam, but let's say I wanted to manually use ExifTool to write the HEIC XMP sidecar data back into the file itself, and then delete the sidecar. Is that safe to do? I can't imagine
this would confuse DigiKam down the road?</div>

Since about 2006 I've used Windows Photo Gallery to organize and tag my photos and videos. I'm trying to move away from it since it's long deprecated software and Digikam is where I want to go (right now using 7.4.0 on Windows 10).</div>

Problem is, I have lots of old videos that have been tagged from inside Windows Photo Gallery (WMV, MPG, MOV, MP4). Let's say I tagged a bunch of videos as "travel". If I want to search for those videos in Windows Photo Gallery I can just search that term and
it will find everything with that tag. I can also find them from Windows Explorer since from what I can tell the tags are embedded in the video file, except for maybe the few MPGs I have. However, if I open up Digikam and search for "travel" none of those
videos show up. Ideally I would be able to read those old tags from inside Digikam because at some point I'll get rid of the old Windows Photo Gallery software. I could instead just search in Windows Explorer, but I just realized that it won't find my Digikam-tagged
video files because it's not searching the contents of the XMP sidecar file. So at the moment there is not one place I can search from and get all the tag results I want.</div>

I followed the Digikam Windows compatibility guide and though it works great for photos, I don't see much for videos. I have a lot of old WMV, MPG, and MOV files that have been tagged using Photo Gallery. The tags show up in the interface as "Descriptive Tags",
and also show up in Windows Explorer as "Tags" if I check the file properties, but nothing shows up in Digikam. If I try to add tags to those files with Digikam, they write to external XMP files. Is there a way to get Digikam to write or at least read those
Windows-embedded video tags? If I can at least get it to read, I can search for those old tags with Digikam if I'm looking for something specific that I've tagged in the past 15 years. Going forward, writing is less important, though ideally I would also like
to write to these files. <br>
