They certainly seemed to mix perfectly in Star Wars Revisited. And judging by the Black Magic examples posted, the detail level between the X0 and the DVD of the SE is pretty much inperceptable. Upconverting that for an HD version would result in some drop in quality, but not jarringly. OCP's Classic Edition sucked because the sources he had access to sucked. I think he was using Cowclops. He might as well have been using a VHS. PaulisDead is offering marked improvement with his Vintage Edit, and Adyway showed what more creative digital rotoscoping/compositing can do, but with a full roster of Black Magic corrected OOT shots the problem is effectively resolved.

This is my plea to the X0 crew: release the OOT-exclusive shots. I'm sure you have many of them done in the Black Magic process. The completed X0 cut still has merit, but if you want to aid the community I would offer that making available whatever work you guys have thusfar completed in this area would be the most beneficial gift we could have.
