Mo-Sys spotlights LED virtual production solutions

Upgrades StarTracker camera tracking system and NearTime workflow for shooting in an LED volume

Mo-Sys Engineering has launched its high frame rate (HFR) StarTracker camera tracking system and extended its NearTime workflow for LED virtual production.

NearTime for LED is designed for shooting in-camera visual effects (ICVFX) in an LED volume. Used simultaneously alongside a real-time ICVFX shoot, the company says it provides an automated background re-rendering service for improving the quality and/or resolution of Unreal-based virtual production scenes.

Using NearTime with an LED ‘green frustrum’, the automatically re-rendered Unreal scene can replace the original background without incurring traditional post production costs.

Mo-Sys also announced the new StarTracker for LED, providing camera and lens tracking up to 240fps for slo-mo shots. In this scenario, rather than drive the LED wall at high frame rates to match the camera, NearTime for LED is used to post-render the Unreal scene at HFR, added the company.

During the slo-mo shot review, the re-rendered Unreal background and the talent foreground are re-combined, delivering a high-quality composited shot.

“We patented NearTime almost eight years ago knowing that real-time graphics quality versus playback frame rate was always going to be an issue with ICVFX shoots,” said Mo-Sys CEO Michael Geissler. “At that time we were focussing on green/blue screen use, but today LED volumes have exactly the same challenge.

“Proxies were used as a smart solution to solving computer processing limits in the early days of digital compositing and colour grading. Similarly, HFR StarTracker and NearTime for LED is a smart solution to shooting slo-mo shots in an LED volume.”
