As yet there's no data structure defined in Wikidata for lists of things -- eg lists of coordinates.
This is something that is recognised as needed, eg to record the boundaries of administrative areas.
However, WD would in any case only store such data for something that was WD-notable -- not a GPS trace for a video, because the video wouldn't have a Wikidata item.
In future however such a video would have an item in the analogous CommonsData system that's planned, and that's somewhere it might well make sense to record a stream of co-ordinates.
A separate issue would be that the co-ordinates would ideally be linked to particular time-points in the video. I don't think anyone has yet done any much thinking about how the system in general would need to be extended to time-based information. Perhaps all it needs it is to simply create lots of different statements, each with a qualifier indicating the relevant time. (As one might have, eg to state different subjects shown in the video). In which case one might not need a single list-like vector item after all, just a lot of separate statements.
Yes. Exactly as James says.
