Latency via IO XT

Post by trabbahabba »

I know, I know, another latency questions.

I am using an AJA Io XT via thunderbolt to input cameras via HD-SDI. All of the AJA presets show up in the sources menu, and I am able to get video feed with no issue.

However, the latency is quite considerable. I am estimating at least a half second if not more. Interestingly, if I use the same camera setup in ProPresenter I get a much more reasonable delay.

Is there something I am missing to reduce the lag? I have tried opening a new comp with only the video feed in it. No luck there.

I am running the application only on a mac with 16gb ram and 1gb video card. I have turned off all non-essential processes.

Any help?
