I haven't heard of any equivalent of EXIF for video. That goes a long way when trying to make sense of random video both for camera settings as well as GPS location if you're trying to correlate multiple videos.
GoPro has a proprietary format that stores live metadata in the videos if I recall. Maybe it’s called GPX? About 6 months ago I extracted GPS coordinates from a video using an open source tool.
I have seen random still images used for this kind of thing: https://nerf-w.github.io/
