Graphics Workflow

Viz Engine supports several workflows with regards to how and when graphics and video are mixed. To simplify it we can say that Viz Engine supports graphics and video mixing in an Upstream or Downstream workflow.

An upstream workflow basically means that graphics are rendered separately and independently of the video signal before it is keyed on top of the video signal, traditionally by a vision mixer.

Opposite to upstream mixing you have downstream mixing. Downstream mixing basically means that graphics and video are composited and mixed by Viz Engine. This can be live video or clips treated as DVE for graphics insertion and/or squeeze backs.
