I don't know exactly how Belbucus did his synch work for the laserdisc soundtracks, but I think he ended up having to make small edits every few minutes to keep it from ending up way out of synch by the end. Little cuts or repetitions as needed to account for the difference in frame count, and of course the amount of editing needed would be greatest around the side changes. It sounded like a lot of tiresome, time-consuming work.

I noticed when I was working on the 70mm mix, when splicing in bits of the 35mm version to replace the altered sections of the '93, that the synch was never 100% exact--the 35mm was usually ever so slightly behind, and occasionally ahead, ranging anywhere from 10 to 52 samples. Obviously this is a miniscule amount and certainly not noticeable (even the biggest difference was only just over a millisecond). I think that is an impressively small margin of error. Out of principle, I lined them up exactly at the sample level for my edits whenever I could, but it probably isn't necessary to be so precise. Still, just getting them close enough not to notice a discrepancy is probably pretty difficult, especially if you're just going by ear and eye.

It isn't critical to include the theatrical stereo mixes for Empire and Jedi if the synch doesn't work, because overall the '93 versions will sound better; it would just be a nice addition. I might be able to synch them, but it would definitely take me a long time and I'd probably be pretty burned out afterwards. lol
