The Definitive Collection laserdiscs actually started our GOUT standard (it wasn’t called “GOUT” back then though, but DC Laserdisc rips were the big thing everyone synced their audio to before the actual 2006 bonus discs existed), so I’d be surprised if it wasn’t perfect sync. That said, the current project now uses the theatrical frame standard, which should not be noticeably different than GOUT for this purpose.

I think there was an early erroneous pressing of the DC laserdiscs missing part of Leia’s welding scene in Empire. Those won’t sync.

But as far as actually using a genlock, I haven’t done it. Does this mean you have? If so, that’s pretty cool!
