Glad to hear your progress Matt. I find English soundtracks hard to sync up so I can only imagine the difficulty with HK soundtracks which were never in sync to begin with.
Imagine pulling your hair out in frustration. It's insane how bad the foley work and dubbing was. There will be a sequence with two gun shots, four kicks and three punches. Half will be spot on, 1/4 just off and the other 1/4 way off. So now try and fix that.
Then you have the dialog. It's never spot for the earlier films because they were all dubbed in post. What a nightmare.
SUPERCOP was easy in comparison to Drunken Master 2 but had its own challenges. That was Jackie Chan's first HK film to utilize on set sound recording and so for dialog scenes it was possible to get it exactly right. Except for when certain lines or scenes were dubbed, which happened here and there. Particularly during action scenes where it was impossible to get rid of rubbery lips that were always there. If music is being played, you just can't mess with it.
By the way, most HK films have the sound of a punch or a kick occurring one or two frames before the action. The Hollywood (Miramax) English dubs have sound work that is typically frame accurate so a gun shot occurs at the exact frame of the muzzle flash. But for some strange reason punches and kicks are typically a frame after the actual contact is taking place. So a full 3 or 4 frames after the original mixes.
