Pattern Key - Blackmagicdesign ATEM Mini Installation And Operation Manual

Matching your foreground and background
Once your foreground is properly separated from your green screen, and you have adjusted
spill and flare suppression, use the 'color adjustments' controls to match your foreground with
the background. Adjusting the brightness, contrast, saturation, and color balance of your
foreground image will help blend it with the background so the effect is more convincing.

TIP When your key is on air, chroma sampling and preview are locked. While most
controls are adjustable while on air, we recommend avoiding changes unless
absolutely required. For example making defined color adjustments if conditions
change unexpectedly.

Pattern Key

A pattern key is used to display a geometric cut out of one image on top of another image.
In a pattern key the key or cut signal is generated using the switcher's internal pattern
generator. The internal pattern generator can create 18 shapes that can be sized and positioned
to produce the desired key signal.
