I know that from version 2021 the metadata in the videos is generated internally, but is it possible to disable this option and work as in previous versions?
I need to copy metadata from a CSV to many XMP and this would be much faster than writing it to the video files.
Yes. But it is not recommended.
Where is the option to do it?
Metadata 2 Options for the file format in question.
BIG NOTE: I DON'T TEST THIS. I DON'T SUPPORT THIS. Bad things may happen.
Ok, I'll try not to use it until it's more tested ;D
I will not test this. It's non-standard behavior. I have enough to do to test standard behavior for metadata.
