About video tagging in digiKam

[wsyxbcl]

An issue about the video tagging workflow, in https://jniedballa.github.io/camtrapR/articles/camtrapr2.html you mentioned

BUT, in contrast to images, digiKam cannot write these tags directly into the video metadata.

Digikam used to have this issue (due to the limit of Exiv2), but since version 8.0 they provide ExifTool as an option for the metadata backend, which enables writing tags into video files (pretty much the same with images). Here is an example of the metadata:

 exiftool ./Downloads/demo.mp4
ExifTool Version Number         : 12.70
File Name                       : demo.mp4
...
XMP Toolkit                     : Image::ExifTool 12.70
Audio Bits Per Sample           : 16
Minor Version                   : 0.2.0
Last Keyword XMP                : Species/Glover's pika
Categories                      : <Categories><Category Assigned="0">Species<Category Assigned="1">Glover's pika</Category></Category></Categories>
Subject                         : Glover's pika
Color Label                     : 0
Pick Label                      : 0
Tags List                       : Species/Glover's pika
Date/Time Original              : 2023:08:28 11:54:52
Exif Image Width                : 2560
Exif Image Height               : 1920
Hierarchical Subject            : Species|Glover's pika
Catalog Sets                    : Species|Glover's pika
...

I'm contemplating whether it's necessary to simplify the existing video workflow, as digiKam db files are no longer needed. Please let me know if there's anything I missed.
