1*The ATEM Mini Pro can output the programme feed via the USB-C connection. It does also feature a single HDMI port, which can be configured to output either; Mulitiviewer, Programme, Preview, or Camera ISO.

Chromakeying in the ATEM

The ATEM range has two different chroma keyers, the standard and the advanced chroma key. The standard will allow you to select hue and luminance levels to pull a key, whereas the advanced version allows you to use a colour picker tool, has more refined controls, and ultimately is faster to use.

Preview output

A* It is possible to utilise the auxiliary output of the ATEM to act as a preview out.

Volatile vs Non-Volatile Memory

When a system that uses Volatile Memory loses power that data is lost. In contrast, a non-volatile system retains its data regardless of power loss.
