Render Sequence

Render Sequences in the Viz Engine Render Pipeline only distinguish themselves from each other on how the scenes key signal gets generated by default, when the lens distortion gets applied and on which assets (Background and Foreground). In general, compositing is done using an alpha blend operation using the key signal between all stages at the very end of the rendering pipeline. The only exceptions are the Precision Keyer and the External AR sequence, which implement their own blending on the Foreground asset.

Virtual Studio, Multi-Layer Virtual Studio

Scene does not generate a Key signal by default. The Key plug-in needs to be used for scene parts that should have one. Both Background and Foreground are supported, No Lens Distortion is applied on Background and Foreground assets.

Fullscreen

Scene generates a fullscreen key. The Key plug-in has no effect. Only Foreground asset is supported, no Lens Distortion is applied.

Overlay

Scene generates no Key signal by default, the Key plug-in needs to be used. Both Background and Foreground are supported, No Lens Distortion is applied on Background and Foreground assets.

Auto Key

Scene generates Key signal for geometries by default, the Key plug-in can be used. Both Background and Foreground are supported, No Lens Distortion is applied on Background and Foreground assets.

External VS

Special sequence for the Unreal Engine Integration. No Key is generated by default, the Key plug-in needs to be used for scene parts. Both Background and Foreground assets are supported. Lens Distortion is applied on the Background, no Lens Distortion is applied on the Foreground.

External AR

Special sequence for the Unreal Engine Integration. No Key is generated by default, the Key plug-in needs to be used for scene parts. Both Background and Foreground assets are supported. Lens Distortion is applied on the Foreground, no Lens Distortion is applied on the Background.

Passthrough

Special sequence for the Unreal Engine Integration, but can be used for other uses cases as well. The Foreground is sent to both the editor previews and the video output. The Viz Engine Render Pipeline rendering is skipped completely, no rendering, no compositing is done, only output processing.

Multi-Layer XR Set

Sequence to render a Set Extension and AR elements from a single scene with the possibilities to cut-out elements via the Matte Scene.

Multi-Layer External VS

Special sequence for the Unreal Engine Integration to render Viz Engine Graphics on top of an Unreal Engine Virtual Studio.

Precision Keyer

When an asset is being put in the Foreground and the Precision Keyer is activated on it, the keying is executed. The chosen Render Sequence does not matter. The Precision Keyer compositing is different than the linear keying. Graphics that have a key are rendered on top, graphics without are rendered behind the Foreground asset.

Matte Scene

The Matte Scene is supported in all sequences except the Passthrough one. When a Matte Scene is used, the key signal that gets generated is a combination of the scene key, the trash matte and holdout matte values.
