This post is intended to get the ear and opinion of anyone that does A/V work at HD or above.
I have built an A/V center where I play games on a monster system and mirror the video to a second system where there is a digital capture card. I pass the video through an A/V mixer that has my Intro, ads, and credit sequences already packaged, so that I can edit on the fly and stream to online services. Right now I am using a 1080p mix, because the capture card is only capable of 1080p60. I do have a 4k UHD capture card (AJA KONA 4 HFR 4K/UltraHD), but I do not have a 4k mixer.
I'm looking for one. Is there something like the Roland V800, or VR-3EX even that does 4k? Haven't seen it if there is.
