A very basic restoration. Newer color footage is actually more prone to problems than old black & white nitrate. Check out the large format projects that Robert A. Harris has worked on. In particular, Spartacus had to be restored from black & white separation masters that had all shrunk at different rates. They had to build a special rig in order to get them to match. The audio for a deleted scene had to be re-recorded as well.

Also, check out these great articles he's written:
