AJA LHi picture drift
I just upgraded to Ultimate 2018.12 and my AJA LHi picture drifts over long uninterrupted playbacks - around 20mins it becomes noticeable. It goes out of sync, but jumps to correct itself. Anyone encountered this?

Re: AJA LHi picture drift
I see something similar in 12.8.3 and 2018.10 with a different AJA interface.
How are you resolving video sync? Randall

Re: AJA LHi picture drift
It's locked to AJA GEN10. Stopping and starting playback resolves the drift right away, but for long-form client playbacks it's not ideal stopping and starting.

Re: AJA LHi picture drift
Correct, sync is locked.

Re: AJA LHi picture drift
Hm, odd. Can't confirm as I'm on a different card (see below) but I'm not getting this with my setup so could be AJA (driver, settings?) related. I've had all sorts of odd strobing effects and weird almost like slomo picture with AJA cards in the past where you had to restart the system to get it back to normal. Like once or twice a day. But this was with Satellite setups. So might be different.
One thing: The BM card has to receive the same format clock as the video in the session to properly lock. Not sure if that's the same with AJA. So if your QT is 1080P 24.00fps the Trilevel sync signal has to be the same. The BM settings will indicate if the card is locking.

Re: AJA LHi picture drift
We have /ever had no issues with Aja LHi at all.
See my specs for details.
