So you're saying there are tags in videos that we could extract just like for images?
from llgal.
Well. In the absence of EXIF/IPTC and friends, there is certainly a lot less metadata available for videos then there are for images. But I had thumbnail creation in mind rather than metadata handling...
But to continue - less is not none.
For example, my Canon 500D makes the following available (via ffprobe):
Metadata:
major_brand : qt

Similarly, from my OM-D EM5 II:
Metadata:

(mind you, both cameras seem to get the timestamps wrong, claiming UTC rather than local time)
