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.
