Latency of blackmagic ultrastudio 4k
We are actually working on a project with live camera feed. As we have close shot, the latency is an issue.
We are working with "old" blackmagic ultrastudio, which have a latency of 280 millisecond. So i was wondering if somebody has experience with the ultrastudio 4k (in thunderbolt 2) and know if it has a lower latency. Or if somebody knows a similar device with low latency results.
Thanks in advance

@zedociel I have used the ultrastudio and a bunch of different blackmagic capture devices and not had this latency. What is your interface, usb3, thunderbolt, or pcie.
Did you test the camera latency? You can film a screen with timecode with the camera you are testing and on another screen show the camera. Record these two screens with a phone or other camera (iphones can do high framearate this is helpful) and compare the delay between the real time timecode and the live feed of the camera.
Thanks for the advice.
We use an ultrastudio express in thunderbolt(1). But you were right, the camera itself has a latency of 122 millisecondes. We pass through an atem to choose which camera we use (+20 milliseconde) and then, the capture itself has a 140 millisecond malus.
That split one problem in two problems.
