    Requires an Epiphan Cloud Pro account. Optimum CPU performance Pearl-2, Pearl-2 Rackmount and Pearl-2 Rackmount Twin are powerful live video production systems; however, there's a limit to the number of concurrent tasks the onboard CPU can perform efficiently. The number of concurrent tasks depends on many factors, like: how many channels you have, how many layouts you have per channel, how often you switch layouts, is the system resizing (scaling) video sources, what frame rate and bitrate is used per channel, are the video output ports used, etc.

    What is downstream chroma keying? To get an upstream key effect using Pearl-2, you can create custom layouts for each video source using the custom layout editor. Then set up chroma keying on just one custom layout. Only the video source that appears in the custom layout with chroma key enabled has the chroma key effect applied to it.

    A common use of downstream keying is to display a persistent image, like a company logo, so that it always appears on screen. To get a downstream key effect using Pearl-2, you can enable the same chroma key effect on all your custom layouts. This way, the same chroma key effect gets applied to everything you stream or record.
