I'm not sure why CC-BY is incompatible with GNU-GPL.
If I had to guess, it's probably because CC-BY attribution
must be made in a way "appropriate to the medium".
In cc-by works, the attribution must "ripple up" to the
top. all attribution must end up in the credits to the
movie at the end of the movie.
GNU-GPL doesn't have that strong of an attribution requirement.
Copyright notices must be kept in place, and I think that's
about it. In a software project, with a "source code" requirement,
this is fine because the copyright notices are usually in the
source code, and maintains a history of who has contributed
to that particular file.
But if you made a GNU-GPL movie, with GNU-GPL audio, stills,
and other content, I don't think GNU-GPL requires that attribution
for all contributers be rippled up so that it appears at the end
of the movie.
The BSD license doesn't have an attribution requirement
like CC-BY, so it can be rolled into a GNU-GPL work if
you wanted to.
Anyway, I think that's the issue. Or at least one issue.
