Black Magic Ultrastudio 4K TB2

[5th Element]

Cool, well thanks for checking back in about this, I have never been that happy with black magic stuff for a while now, it always seems to work but only with a lot of hassle.

Glad to hear about the Aja, Latency isn't usually my biggest concern as much as just looking like a smooth capture without any frame dropping, or just without looking like it's an internet stream… which seems typical with external cards.
Hopefully this will give some life to external captures over thunderbolt 2 without an expansion chassis,

What machine were you testing this on?

The 4 BNC Connectors of the AJA are for the different SDI Formats, like 6G SDI where you might need 4 x BNC to get the full Signal.

So it's just 1 x SDI in in total (from SD-SDI up to 6G SDI)

I did the testing just with a Macbook Pro, But I think that a faster machine would not reduce the latency of less than 2 frames..

Best
