NVIDIA Quadro SDI Capture


Currently the NVIDIA Quadro SDI Capture card can only be used with the NVIDIA SDI option. The Vizrt application of this card is mainly in time-critical environments like virtual studios and sports applications, as it has a stable latency from input to output (of four frames).

The time used for video transfer from input to the GPU and back to video output is a lot less than any other solution Vizrt currently offers. Hence, scenes with four video inputs as texture still have a lot of rendering time left per field/frame.


The card has five BNC connectors. Four connectors are used for input, and the fifth connector serves as a loop-through of input one.

Drivers for NVIDIA Quadro SDI Capture Card

Use the latest NVIDIA GPU driver and WDM (Windows Driver Model) driver for the capture card. Vizrt does not recommend a specific driver version beyond using the latest version available from NVIDIA.
