When it comes to the Blackmagic Design DeckLink Quad HDMI Recorder 4K PCIe Capture Card vs Magewell Pro Capture Quad HDMI Video Capture Card... I read reviews and some people said they couldn't get Blackmagic to work, but if they did it was fine... And that Magewell is just better out of the box to "just work." Obviously I'd rather not spend an extra 3 or 4 hundred dollars if I don't have to. Want to stream 4 Panasonic GH5s during a podcast with the best quality and reliability. Any suggestions? Even if it's not one of these 2 choices? Was also looking at the ATEM Mini Pro, which is currently difficult to get, but not in a rush. Thanks!!! :)
