Editing stereoscopic footage is often performed in 2d.
This is how we started, and after reading about the editorial process that was used for Life of Pi we decided we needed to be editing in 3d. We purchased 3d reference monitors. Now, we're going big screen with the acquisition of a Barco DP4k-P. This is a 4K post production projector made by Barco, a Danish company known for high quality displays and theatrical projectors that has an accurate, wide color gamut that's ideal for critical color decisions. We're also outfitting this projector with the RealD passive 3d system.
