Local check
Read video container tags.
The check lists title, artist, album, comment, description, genre, date, and copyright from the first container metadata block. It stops at 150 MB.
What this read leaves out
Stream tags and other container fields stay off this list.
The cloud metadata job is separate. It replaces supported device and capture tags on a new copy, and it uses one cloud output.
A tag list does not guarantee reach, approval, or a lower ad cost.
