Absolute Sync in Virtual Production

In XR stages, matching the physical camera movement to the virtual engine render is the difference between a believable shot and a broken illusion. Our XR Tracking Latency Calculator models the entire pipeline from sensor capture to SDI output.

Unreal Engine & nDisplay

nDisplay introduces predictable buffering delays. By understanding the nDisplay frame count (typically 2 frames), engineers can set the correct LiveLink delay in Unreal Engine 5.4+ to pre-compensate for hardware bias.

Genlock Phase & Shutter

Beyond frames, sub-frame alignment via Genlock Phase Shift is critical. This ensures the LED refresh cycle starts exactly when the global shutter of your Sony Venice or ARRI Alexa opens, eliminating rolling artifacts.
