True.

Well, this seems to be the basis of the distance estimates if
they are gulls, so perhaps I should have said "unresolved if they
are gulls". If they are just blob-shaped then perhaps they are
fully-resolved blobs. The argument then moves on to dyanimical
features like variation in brightness, angulkar rates and so on.

I haven't seen the whole film either. I suspect few people have.
I have only seen short clips and still frames. It would
certainly be interesting to watch from start to finish.

I suspect we have to assume that 16mm is the film width, but
that frames are ~ 8mm in the longitudinal direction?
