For me, making a master theatrical cut version is very important. My method is to use TB and ORF along with the LD, DVD, and BR versions. While some sections of the movie are vastly different, the majority has remained the same since the theatrical version. I found that Adywan’s reconstruction is missing 2 frames that are in the DVD and Blu-ray. They appear to be at a reel change so I pulled the frames from the home video. I’ve had to the same thing with 1 frame in Empire and 8 in Jedi (2 each at 4 reel changes), so having to do it once for TPM from the same sources makes sense. As the DTS tracks are by reel, and they overlap, this means that the DTS should cover these whether you chose to add them back in or leave them out. As I just got my hands on the original DTS discs and I’ve been working on the SE video mix, I have not yet had the time to extract the TPM and ATOC audio (my goal is not a DTS track, but an accurate AC3 track and a mixdown to Dolby Surround encoded stereo).
And TPM was not cropped right initially, though the cropping matches the SE release. So to stay faithful to the theatrical version, you have to match the original cropping, or find a way to restore the rest of the frame in the changed shots (quite hard so not something I’d aim for). That leaves about 5 shots that only exist in the lower quality (well, two full shots, one partial shot and two shots that transition to a low quality shot). Better than ATOC that has 4 shots for which all we have is the camera print of. I’m pretty much done except for pulling the DTS audio and making sure my edits line up and have Cinema DTS audio. If I were aiming to do this, I would start with the HD broadcast of the DVD version. The cropping and most of the edits are pretty close to the original theatrical version. Then you can use the Blu-ray to patch any glitches in that version (and crop it to match). At least that is the way I would do it. A lot less work. I’m sticking with only original versions so for 5 out of the 6 I am limited so I’ve gone ahead and used the ROTS DVD version with the one wipe restored as the theatrical version (it matches the leaked theatrical version that I have exactly).
