XPression Setup

Graphite CPC uses XPression as the main video engine for the switcher. Video inputs and output pass through XPression to be controlled by the switcher. XPression must be configured to offer the best performance for the switcher functionality.

Note: For detailed information on setting up XPression, refer to the documentation that came with XPression.

When configuring XPression to operate with the switcher there are a number of setting that impact how the system performs or what inputs or outputs are available.

  • 2x MultiSampling — The Hardware Renderer (Edit > Preferences > Hardware Renderer) should have the Anti Alias set to 2x MultiSampling. A hardware adapter must be selected to set the Anti Aliasing.
  • Video Inputs — Video inputs to the switcher are XPression Internal Framebuffer outputs or NDI® streams. Framebuffers and NDI® outputs are set up from the Inputs/Outputs tab on the Hardware Setup dialog (Edit > Hardware Setup). NDI® streams can also be assigned directly to switcher inputs.
  • Video Outputs — Video outputs from the switcher are assigned to XPression Virtual outputs or NDI® outputs. Virtual and NDI® outputs are set up from the Inputs/Outputs tab on the Hardware Setup dialog (Edit > Hardware Setup).
