ATEM mini pro: What are Upstream and Downstream Keys!

In this video, we'll explore the concepts of upstream and downstream keys, and how they can be used with ATEM switchers to create professional-looking video productions. Whether you're a beginner or an experienced user, you'll learn valuable tips and tricks for using these powerful tools.

First, we'll define what upstream and downstream keys are, and how they differ. Upstream keys are graphics or images that are overlaid on the main video source, such as logos or lower thirds. Downstream keys, on the other hand, are overlays that are added to the final output of the switcher, such as subtitles or graphics.
