Post GPU Technology Conference Session: A Workingman's Guide to 3D Video Editing

With 3D content proliferating, more and more people are becoming 3D content creators. The audience of 'A Workingman's Guide to 3D Video Editing' got a high level walkthrough of the ways and hows of creating and editing 3D video, along with specific tips and guidelines from NVIDIA's Ian Williams and Kevan O'Brien.

High-end 3D video still belongs to the movie studios, but prosumers are getting more options as 3D cameras come on the market and 3D TVs appear in more living rooms. GPUs are playing a role in the proliferation of 3D as well, since the accelerated processing power makes it dramatically easier to edit 3D content and perform some of the computations needed to reconform content after editing. And at the high-end, you definitely need GPUs, or you're facing unworkable processing times. As Kevan put it, 'You can't do real-time 2K or 4K work without a GPU behind it.'

Ian, the director of NVIDIA's applied engineering group, took us through the ways that 3D video can add value and can be distributed (for instance, YouTube is a boon to the novice 3D videographer). Some of the guidelines and best practices:
  • go for a camera that gives you want full manual control, avoid high-contrast because you'll get ghosting on LCD technology
  • group objects and people close together because the lens will naturally make objects appear farther apart
  • don't do a lot of close-ups, and pan slowly ' otherwise you risk giving your audience nausea from the movement.

According to Ian, 'It's all about subtlety in 3D.'

The real highlight of the session was when Kevan, a filmmaker, showed exclusive previews of a new work in progress, 'The Time Machine.' The entire audience put on NVIDIA active shutter 3D Vision glasses and got to see the editing process in real time. Very cool.
