What is the preferred IO for Premiere Pro?

[Miro Segura] “In my Mac system preferences I set the audio out to “Headphones (Headphone port)”

I’ll try that. Thanks!

If that doesn’t work, try Walter Biscardi’s solution:

Premiere Pro > Preferences > Audio Hardware

Set that to anything OTHER than AJA Kona. I have it set to Built In Audio.

In System Prefs > Audio Output I have it set to AJA Kona.

Yes, that’s a weird setting in the Audio Hardware but that’s where it needs to be.

As for the choppiness, we have that on our four core machine and have determined that the four core will not work with ProRes footage playing back through the AJA Kona. An 8 core machine works just fine.

As a test though, bring up your Activity Monitor and the CPU Activity. See if the cores max out when trying to play back the footage with the AJA Kona being used for output.

For what it’s worth, over the last 10 years I have used 4 different hardware i/o products: AJA, Blackmagic, DPS, and BlueFish. From an engineering standpoint (though I’m a novice-level video engineer), the AJA hardware was the best at complying to what video output should be, based on looking at ‘scopes, colorbars, etc. (although DPS was pretty good too).
So I would keep your AJA hardware, and stay on top of driver updates for Premiere.
