Stereoscopic 3D LiveViz and Compositing on location

Blurring the Line between Post production and Production:

The Decade of Real-Time 3D Moviemaking:

Here’s the dilemma; many productions are now going stereoscopic 3D. (the term stereoscopic should suffice, but we add 3D to prevent ambiguity), and there is a need to preview a live chroma or green screen “key” in 3D, because compositing and match moving in S3D is a whole different beast, more challenging than doing the same in 2D. Simple “foot contact” of actors, with the ground gets even more complicated to composite in S3D than it is in 2D. A bad S3D composite will show up as people floating off the surface of the ground. In 2D, without stereoscopic depth cues such problems are rare and easy to cheat.

The practice of compositing used to be the exclusive domain of “post production”. In a typical movie, compositing is done in post. It still is today, but high performance (HP) computing coupled with the fall in prices of hardware and technology is making it feasible for desktop replacement laptops to be brought on location to give instant visual feedback. Industry standard software such as Maya, compositing sofware such as Nuke and AfterEffects, and realtime NLE software that can assemble and cut “dailies” as soon as they are shot in full stereoscopic 4K can now sit on a portable laptop and give the director and crew instant visual feedback.

Being based in the UAE, where temperatures sometime soar above 40 degrees (celcius), does not allow us the luxury of procrastinating and running multiple takes of scenes at many times. The need for realtime visualisation of final composites and other parameters while making a stereoscopic 3D movie makes us have to innovate and think up solutions that are still not de-facto even in Hollywood. I personally believe that this will be the decade of real-time 3D movie making: from 3D cameras becoming more self contained, to doing away with cumbersome Beam Splitter 3D
