Good:
- sharper picture, nice level of detail (the starfield in Shot 1 is nicer than any of the others - even the official DVD! - and you can see the engines of the blockade runner quite well).
- Whites aren't overblown and blacks aren't crushed, see shots 6 and 8.
Bad:
- doesn't show up on screenshots, but quite a lot of "speckles" or drop outs in the video. Discs need a thoroughly good clean.
- colours are not as saturated as the other versions (shot 4)
- still a presence of halos/ghosting/edge-enhancement/whatever-you-want-to-call-it (shot 7)
I think I'm going to leave the video and concentrate on other things for now, i.e. splicing in the screen wipes and syncing the English audio. I've realised you could play with the settings and post-processing for months and still see things that need fixing - regarding the colours, if I increase the saturation then colortools plugin detects some of the reds (e.g. in shot 10) are too high. Instead of messing about with reducing individual colours, I will use the video as it is now and go on to make a non-anamorphic DVD5 "screener" version to use as a baseline for future enhancements.
