In this mode, the real-time engine must use the 3D scene model when rendering. The alpha channel output takes depth into consideration to pre-cull real-time pixels where playback pixels are in front.
Chroma Key options are available if simple compositing is all that is required, to avoid the need for an alpha channel.
This could, as in full mode, composite any combination of multiple gaming inputs only, and/or with multiple playback resources, though without the full depth and stencil feeds, offers none of the stencil blending effects.
