ok, I have now three videos for you:
1. For Hedo to watch:
Better than the trailer. You should also watch the next video:
2. Small video about the motion, and the emotion capturing
3. And now a stunning 30 minutes video interview with Cameron sitting on a cheap couch, talking about the development process of the tech that made Avatar possible:
This is brilliant. You can't even begin to describe in a few words, just HOW MUCH work this requiered. 1.5 years of R&D just for the basics, and the design on Pandora. All while developing a new 3D camera, then developing a camera that can take you through the CG set in real time ON the motion capturing set BY moving the "CG camera" through it. Then combinging both technologies so that you can film real humans WHILE having the CG sets on the camera.
After that they needed about 9-12 months for EVERY character individually to get the finetuning on the mimic capturing done. All with horrible drawbacks and no one to turn to, because they were the ONLY ones even trying to do it. As cameron said, it wasn't just hard work, but also very scary, because he had no idea if it would work in the end.
