you're editing and things are cut and moved around, is it difficult
to get the pre-recorded music to sync up?
The picture cut of the movie is always changing sync
until the very last moment before release. Most often, the music is
written and recorded for an earlier version of a scene than what
appears in the final cut. Ken Wannberg, John Williams' music editor,
has the difficult task of recutting the music to refit the new sync.
This can be an extremely difficult job. He is the one solely
responsible for making it fit after the fact.
