Kona LSe Sync Problems
Sync Problems – AJA Kona LSe
I have a client with a 3GHz Dual Core Mac Pro with a Kona LSe card who is working in 10 Bit using the AJA KONA LS-PAL 10 Bit Uncompressed setup. He is running OSX 10.4.9 and FCP 5.1.4
The footage is in sync on computer displays but when viewed on client crt it is 3 – 5 seconds out of sync.
Any ideas?
Cheers.

Seconds? Or is it frames? 3 or 4 frames out of sync is very typical, 3 or 4 secomds is very weird.

It sounds like your client is not monitoring audio from the Kona Lse output.
I agree with David about the delay.
Please give us more detail about your clients wiring and sequence setup so we can help.Best Regards

The FCP’s frame offset is set to 0 (Systems Settings/Playback Control/Frame Offset) ands the client is monitoring both pictures and audio directly out from Kona LSe card.
The sync problem looks like the audio is delayed by 3-5 seconds. I have not been on site to look at the machine yet but could it be that the Kona card has been fitted by the client in the wrong card slot on the Mac Pro and the card needs to be moved to either slot 3/4 (in either top 2 slots) and that the Expansion Slot Utility bus lane config needs to be optimised.
I can’t get on site to client until Tuesday as its a bank holiday in the UK, I will bench test this out in the office and let you know. But if you have any other ideas please let me know.
Cheers.
