Using the Classic Media reconstruction of Ghidrah is a fool’s errand as well (I realize you acknowledge the sync errors, but there are unnoticeable visual ones as well). It’s not very accurate and pretty clumsy at times. If you want to carefully re-create Ghidrah, use an original 16mm source like I did for my SD reconstructions. Also, the best (incomplete) source for the audio is the 16mm print on the Australian Siren Entertainment DVD since it’s not an old 1 inch tape master.
Ghidrah also has a shot that’s longer than in any existing Japanese source (a shot of Infant Island when the Shobijin summon Mothra).
The end title you did is pretty good (nice work removing the “Owari”), but it’s not accurate. The 8mm Ken Films 'scope version of Ghidrah shows that the end title is supposed to be stretched to widescreen:
BoxMonster and I collaborated on a version of the opening credits in 720p with fake gate weave and grain for the freeze frames and a font that’s very similar to the original. I still have the .mov he sent me.
Will you guys be pooling your resources, perhaps? Red Menace is making the most out of what he has, but it appears to me you have even more resources at your disposal.
If it’s any help, I guess so.
