No, synced is a timing thing. All GOUT-synced audio will work with any GOUT-synced video, so people’s lips match up with the words coming out of their mouths, etc. Silver Screen isn’t GOUT-synced, so you are a little more limited in your audio options (or you add dark frames for the missing video to make it GOUT-synced, either way).
…
Just to clarify: Star Wars Silver Screen Edition v1.0 is not GOUT sync’d but v1.6 is.
Glad to hear. Do you know if filling in the gaps was accomplished with GOUT frames or black frames, or some other method?
All kinds of methods were used - occasionally frames were repeated, sometimes they were recreated from nothing using photoshop and other tools based on nearby frames, and in at least one case frames were taken from the blu-ray, color matched, blurred and grained with some dirt and dust added to make them blend better. No black frames were used, except between Reels 1 and 2 where it had faded to black anyway, and no GOUT frames were used either. I’m quite pleased with the results.
