This thread appears to be upscaling the GOUT and 97 SE broadcasts. I doubt I have his skill, but I am attempting the same thing. For me it is more about the colors. I’m attempting to restore something close to the original colors for both versions. It is the first stage in restoring the colors to the Blu-Ray. For A New Hope that will be hard. But one thing I have found is that my efforts to enhance it look best at 720p and do not downgrade well to 480p Widescreen DVD resolution. I think I have the colors for the GOUT and am very close for the SE. Along with the SE, I’m including the broadcasts of The Phantom Menace and reconstructions of the theatrical version of AOTC and ROTS (using the extant theatrical camera print for AOTC and the Blu-ray of ROTS to correct the DVD versions) and using the cinema DTS disc audio for all but ROTS (where the DVD audio is the same as the theatrical). Plus I’ve found information that has led to me creating a slightly enhanced GOUT of the original 77 theatrical version of Star Wars (the no episode number opening crawl, 3 different effects shots, and different end credits). So I’m going to have 10 files in the end.
You can also use the cinema DTS disc for Revenge of the Sith since DTS is of a higher bitrate than Dolby Digital.
Also, make sure to convert it to DTS-HD Master Audio 6.1 Matrix and not regular DTS-HD Master Audio 5.1 since it’s presented in cinemas in DTS-ES 6.1 which is matrixed 5.1.
If you don’t make it 6.1 Matrix, then it’s not actually the theatrical version.
