YSTV 3D: Difference between revisions

Having been lamenting over the death of HD1 (one of our first three HD cameras), [[Michael Chislett]] had the crazy idea of going 3D. As usual, there would be no reason for this random idea.

The tricky part with 3D camera rigs we found, was that with even the slightest inequality between the two would result in the viewers feeling sick! With cameras that sampled less light than a pair of peanuts, we relied on some simple, bright test patterns made from LX tape marked off on the walls of our studio to adjust focus, rotation, zoom, light levels etc. Lastly, the position of the cameras relative to the “target” was vital: too close, and the target would pop out of the screen so far that when edited, it would break out into left and right eye images, thus losing the illusion. Too far, and the 3D effect would be minimal, and wasted!

Next step is to put some content in front of the lens, and simultaneously record on both cameras, with the trusty clapperboard providing the sync points for editing later.

The two cameras were then rendered together in anaglyph mode, with rotation adjusted to the nearest 0.1 degrees, as anything worse gave Mike dimensional headaches. Had there have been a 3D colour screen to watch on, we would have used colour. A note for the future: watch out, render times are 4x their 2D equivalent!
