I am working in a project that is purely Apple ProRez LT 60fps 1920x1080. A project I began long ago in Final Cut Pro. I have since transferred a copy of my project via XML to Adobe Premiere CS6, so that I can run the two edit platforms in parallel to one another while I'm slowly making the transition to Premiere CS6. I'm very enthusiastic about the change and really am enjoying the new interface. There's just one problem...
Not one quicktime seems to want to play inside of premiere without drifting the audio after approximately 20-30 seconds in. All audio is coming through clearly upon playback, without dropouts. But, after 20 seconds, it begins to drift out of sync. I'm a visual effects/animation editor and audio sync is probably the MOST IMPORTANT asset to me in a great peice of editorial software. You can imagine how thrilled I was to pickup a copy of Premiere after all the headaches from sync issues with Final Cut Pro...
Below are my settings...
Now, believe it or not, as I type this, I might've figured out the problem through some trial & error, but I'd still enjoy any advice from the pros...
1.) In preferences, under "Playback", under "Video Device:" when I "setup" the AJA KONA LHi card, I feel like I need to select the format of my sequence. In this case, "1080p60". And then playback seems to operate in sync.
2.) In the "AJA ControlPanel" software (pictured below) under the "Format" heading, my "Primary (frame buffer) format needs to be at my sequence settings as well. "1080p60a"
I'm still feeling a little lost as to why I can't have Premiere doing the controlling here, but maybe I'm not doing something correctly. At any rate, I figured there might be a number of other Apple ProRez LT 60fps projects out there that might be having a similar situation so I figured I'd post.
All information is appreciated.
