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.

I have upgraded to Kona 3 drivers to version 3.3 and artifacts are still there. They only appear when the shot is first re-sized, graded using FCP color corrector (eg increase luma by a large amount)and then rendered. The problem is on the analog/SDI video ouput on grade 1 + client monitor the FCP’s Apple display in the FCP’s canvas looks ok. You are right it does look like a incompatibility problem with FCP Version 5.1.2 and all existing Kona 3 drivers (upto version 3.3) I have contacted AJA and they are going to look into problem. I will let you all know the feed back. Cheers Malcolm

That’s exactly the problem I have got rendering either in RGB or 8-bit solves the problem but takes me away from the 10-bit purist world.
