[digiKam-users] Migrating from Windows, can Digikam read embedded video tags?

[Gilles Caulier]

yes.

digiKam has a maintenance tool to sync file metadata with digiKam database.
As all tags are always written to the database outside the fact to manage
or not XMP sidecar (optional), you will be able later to update HEIF
metadata with digiKam tags.
