When using the Hardware Encoder in Recording, Streaming and MultiCorder, and an NVIDIA graphics card is installed, the following guidelines apply.

 

 

All recent GeForce graphics cards support up to 8 simultaneous encodes per machine, regardless of the number of cards installed.
(vMix recommends a single graphics card per machine - additional graphics cards can negatively impact live workflows)

 

The maximum resolution and frame rate is 3840x2160 @ 60p and a GeForce 1080 Ti or higher is recommended when recording 4K.

 

 

The vast majority of Professional (Workstation) cards do not have a simultaneous encoding limit. As a general rule, each card's encoding chip can handle 1x 3840x2160 @60p. This can be subdivided for HD sources, so 4x 1920x1080 @60p or 8x 1920x1080 @30p is possible on these cards. Some cards offer 2 onboard encoding chips.

 

NVIDIA lists the number of encoding chips and simultaneous encodes per card below:
