So Gents,

I had a longer test with this Ultrastudio 4K just to realize, that I was never able to capture one single frame with that..

I'm not sure if this (brand-new) unit was broken out of the box or if the hdcp handling of the device is simply a nightmare, but I wasn't even able to get something into this with an ImagePro, neither over SDI nor HDMI, so to cut a long story short, I lost the faith I never had into this...

I did testing with an Aja IO4K and this item works like a flaw, it did from the first second what it should do.

From latency side it looks like being on the 1.5 - 2 frames which would be acceptable for me..

Also it's just one input into the Mac, the different inputs on the Aja can be switched by the software

Will do more field testing in production environment on the weekend and will let you know...

Best

Rolf
