4K video
« on: January 27, 2016, 10:23:46 AM »
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.

Turns out this card does not support capture at UHD 60fps (2160p60), so I have ordered another card. I have a hardware compressor capable of 2160p60 and probably will have to use a high capacity SSD RAID array to get the throughput. Unfortunately, my Internet does not support uploading video of that size to YouTube. At least not yet. Fortunately, by moving the audio system outside of the PC case I can add a Thunderbolt card, which should give me five times what I need.

For now I am satisfied to see how clear 1080p60 is coming out.

Yeah, I can't share AHIII videos yet, obviously, but what I was looking at was the terrible shape some of the AHII videos end up in once they are on YouTube. I think I have away to avoid that now.
