Recomendation for card to acheive minimum latency
Posted: Sat Jan 28, 2017 1:13 am
We are considering using a BMD cards in an upcoming Windows 10 based system which requires low latency.
In one mode, video comes in from either 3G SDI or 1080p60 on DVI. We are flexible which is preferable, and only one need format need be supported. We need to display the data with minimum latency on a monitor, while simultaneously acquiring to disk, possibly at a lower frame rate. In this mode, there is no additional processing or overlay of the video - just unmodified video in to video out.
In a second mode, the same monitor needs to act as an ordinary computer display, including displaying of the previously acquired video. Latency is not important in this mode.
What would be the best solution to provide minimum latency for the first mode?
What is the minimum achievable latency at 60 fps?
From this post it looks like 2 frames is possible on an Intensity Pro 4K.

Thanks a lot
