What if you could use a 4K actioncam to broadcast live video from HDMI using Telestream Wirecast? That's what I set out to do this week. But I don't want to just tell you the best one(s) - I want to show you.

We have six 4K actioncams that B&H sent us, and we've tested each and every one of them. Not all of them worked with live HDMI output, but the ones that did will be put to the test: how do they look? At what digital zoom level does the picture begin to degrade?

I want your opinion: which camera wins this round?

Sasha and Jeff were in studio too, and by the end of the show Sasha had officially un-friended Jeff (IRL)... and you'll have to watch to find out why.

Enjoy the show, and thanks so very much for supporting Category5!
