I take back some of what I said about the color levels. Especially the reds. Scanning a larger chunk of the movie (about 40 minutes) I see that the reds are plenty saturated. Also, the blues are full as well (I so much wanted more blue for R2 but that would be bad). Using the Color corrections tip from the X0 Project's web site I maxed out the saturation. Set like that I found at the beginning I couldn't boost most colors without the walls turning non-white (as was observed earlier in my posted clip with the pink-tint). Now I will confirm this later (and post screenies for your approval), but it looks like boosting only green and yellow (and not red, blue, magenta, and cyan) 25% allows us to improve the overall appearence without taking any colors past the 75% target and without adding ANY tinting to the white walls, troopers, or Leia's clothing (maxed out saturation confirms this).
As far as the audio, I took my PCM audio clip and added about 1/3 of a second less than 17 seconds of silence (during the THX logo). The audio appears to sync perfectly for about 30 minutes from the beginning.
Now I can add/remove blank audio from the PCM clip further to see if I can keep going like this but 2 things stand in my way.
First I have to free up a bunch of drive space but given time That's easy enough.
What would be monsterously helpful at this point would be if anybody could quote me as closely as possible the side changes for both the DC edition and the French PAL (? Moth3r's source). I'm thinking that's going to be the key blocks where the audio will need to be resynced each time.
If that's the worst of it, this project should work out great.
