James Cameron Labors Over ‘2.99-D’ Conversion of Titanic
“It’s an extremely labor-intensive process. I have a team of three technical people who look at all the images several times over, then bring it to me,” he continued. “I go through it frame by frame during four-hour sessions, multiple times, until the depth is worked out. Even then, it’s 2.99-D, not really 3-D, but the point I’m trying to make is that most conversions that are done in a hurry-up way in post-production are 2.4-D.”
Regardless of your opinions of the movie, the technical details are pretty interesting.
