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

[Gilles Caulier]

hi,

the Q is : where is stored this information set by the Microsoft
application?

- in a database = we cannot extract it
- in XMP sidecar = we must be able to extract it
- in file metadata = we  must be able to extract it

About HEIF : yes we support this format, including metadata.

To be sure, share samples to be sure and test.

Best
