How to add metadata to mp4 video

Have been able to add keywords and change capture time in Bridge (all versions) up until recently. 

However, created a few with Samsung Galaxy S25 Ultra this month. None of these are able to be edited by Bridge - tried all versions, including the latest beta. The videos were taken in H.264 format.

Current version Bridge is 16.0.2.23

Is there anything else I can do?
