How to capture RGB signal without input lag? [Blackmagic Intensity Pro 4K]

[Arian]

I posted a thread on the Blackmagic site, but I thought it couldn't hurt to do it here too.

With most devices I capture from, they seem to be YUV-friendly. However, with the more contemporary Nintendo Switch and PlayStation 4, they seem to only support RGB output.

The problem is that with RGB, I get a fair share of input lag, and when I switch to YUV, I get a black screen, no visual output to speak of. The audio problem is rectified, however.

Is there any way to either practically convert the RGB signal to YUV or to capture the RGB signal without input lag? What do I do to fix this is the million dollar question here.

Any input is greatly appreciated.

That's for playing or capture only ?

I know with old sony dvd recorders (models rdr hxd 870 up to 1070) they accept RGB as input (on the scart) and you can output YPbPr (dedicated cables) but pretty sure there'll be some lag, it sounds inevitable
