We haven't used FCP in a while but now we're dealing with a project and a client and face this:
When reaching an "unlimited" (orange) segment, frames are skipped as they should, but the rest of the timeline from that point on will be out of sync (Kona is 0.5 to 1 second behind the computer and audio, even though audio is playing through the Kona). Practically, the operator has to hit stop and start after every single orange segment in order to watch his sequence.
We tried different (Nehalem) computers, different cards (Kona3 and LHi), different (ProresHQ) footage, different storage, and different OS (10.5.8 and 10.6.8) and AJA drivers (8.1.2 and 10.1 correspondingly). Same behavior every time.
I have quality set to Dynamic and tried frame rate in Full as well as Dynamic with same results.
Is this normal behavior? Have you experienced it? I was unable to find any online references to this. Kona cards are designed to work in unlimited RT with FCP7, and losing sync isn't how Unlimited RT was designed. Our Blackmagic card stutters in orange segments but never loses sync.
