There are at least three copyrights potentially at play:

* Any copyright(s) subsisting in the music,
* Any copyright(s) subsisting in the moving image,
* The copyright in the film, created by synching the music and moving image.

If the music is under CC-BY-SA, then the copyright in the synching is
thus also under CC-BY-SA because the licence treats it as a derivative
work. They remain as separate copyrights.

Note that the text of the licence makes no express comments about
synching music that is not under CC-BY-SA, which is the premise of
your example.
