One of the most intriguing recent trends is the return of stereoscopic 3D. And there are plenty of developments on the horizon at NAB.

Stereoscopic 3D is popular again as advances in digital acquisition and post-production technology are now offering better control over the precise alignment of the left and right images that make up a stereoscopic 3D picture.

Consultant MC Patel says: “We don't even understand half the issues that are involved in making good stereoscopic television. There will be loads of little things that come out at NAB.”

Shooting in 3D requires a special two-camera rig and generates a large amount of data. For post producers this means data management headaches and the need to increase storage levels while dealing with slower processing time.

One of the best places to learn more about stereoscopic will be the Quantel stand. The company behind colour correction tool Pablo will be demoing the Pablo 4k with stereoscopic 3D option along with a range of other stereo 3D post-production technologies.

One of the first compositors to embrace 3D is Nuke version 5.0. This Foundry- manufactured software has tools for viewing left and right images and allows colour correction and paint to be applied to the left and right eye at the same time.

Other 3D options include Scratch from Assimilate, which is the only program to be able to natively work with the Red One camera's R3D files, and SpeedGrade DI 2007, which has the DualStream stereo-scopic module and support for live playback and grading of RAW files.
