I want to start streaming or at least record gameplay once so I can cut and edit it later. Now I wanted to ask what I need and how I have to connect the whole thing.

But now I want to stream or record gameplay from the PS4 and I keep stumbling across the term Elgato. Do I need this device for this? At the moment I have the following hardware:

PS4 connected to 4K monitor (predictive because of PS5)

How do I have to combine all of this so that I can record / stream?
