Well, my first encode to Lagarith (YV12 lossless) finally finished after about 50 hours. Here are my settings changes and the resulting screenshots. Remember, these are Lagarith intermediate screenshots, so there will be another generation of MPEG2 encoding after this. These shots are meant to show the effect of the script processing, not the final re-encoded DVD results.

The only values I changed are below.

Levels(7,1.14,255,0,255)
Tweak(sat=1.14,hue=-2)

sigma = 4

Scanning through the film on my PC, I'm quite happy with the results. There is the expected slight loss of detail and cropping at the edges of the frame, but that's the tradeoff for the correction of gate-weave/frame wobble and anti-aliasing. I don't know if it's possible to coax a bit more detail and sharpness out of the script without causing other problems.

Many shots clearly benefit from the level changes (Leia with blaster below) with improved contrast in the washed out blacks and other shadow areas. I changed the level less than the default script because of the problematic shot of Luke below. If not for that shot, I probably would have used a Level setting of 8 or 9. Actually, scanning through more of the film now, I found quite a few more shots that are also at the threshold of acceptable darkness at 7. Ideally, a shot by shot correction would be allow me to use larger level adjustment on most shots, but I don't think I want to invest the time in that, considering the source.
