Tutorial: Using SuperSource on the Blackmagic ATEM Mini Extreme - Streaming Media Producer
Blackmagic Design calls its PxP feature SuperSource and it used to only be available on their highest-end switchers, the ATEM 2 ME Production Studio 4K, ATEM 4 ME Broadcast Studio 4K, and ATEM Constellation 8K. While much of the workflow is the same as we will discuss here, in this tutorial, we will be discussing SuperSource on the newest and more budget friendly ATEM Mini Extreme and ATEM Mini Extreme ISO video switchers.
