FCP getting repetitively sluggish with Kona LHi
I’m a new Kona LHi owner. While editing, every ten-twenty minutes my timeline navigation becomes strangely sluggish, taking 10 seconds or so to respond to commands. This is immediately solved by “refresh a/v devices,” which leads me to believe it has something to do with my FCP-Kona communication. Any thoughts about a permanent fix for this?
It’s a little annoying to keep hitting option+F12, but not the end of the world. Mostly, I’d just like to understand what’s happening.
Mac Pro 2×2.93 quad core xeon, 32gb RAM, OSX 10.6.3
FCP 7.0.2
Kona LHi 7.5.1 with breakout box
Projects are all SD, Setup: AJA Kona LHi: 525 29.97 Apple ProRes 422
Footage is coming SD-SDI in from Digibeta, outputs are Component to broadcast monitor and SD-SDI to D-BetaThanks,

Also, my slot arrangement:
1: ATI Radeon
2: Kona LHi
3: eSATA (glyph) card
4: emptySome things I already tried:
AJA conflict checker: all good
Trashed FCP prefs
Uninstalled/Reinstalled Kona drivers -
Is it your hard disc going to sleep? Look in system prefs, under “energy saver”, and uncheck “put hard disc to sleep when possible”. Might be the problem, might not but it should be unchecked for an edit system anyway.

I think you want your LHi in slot 3 and your storage card in slot 2.

Thanks for the thoughts, guys.
Scott: My energy saver prefs are set for hard drives to not go to sleep, so that’s not it. I’ve learned that lesson before. Also, when I’ve dealt with hard drives slowing me down in the past, especially externals, I could actually hear them spinning up to speed while I was waiting for FCP to respond. In this case, hitting option+F12 restores response time instantaneously, with no noticeable hard drive chatter.
Jeremy: Your suggestion is actually how it was originally installed for me (by Tekserve in NY), but AJA tech support, and their documentation, has it spec’d for the AJA card in slot 2 (according to AJA tech support, slots 1 and 2 are the “fast lanes” on a Mac Pro). So I switched the eSATA to 3 and the AJA to 2.
Any other thoughts out there, short of trying a new LHi?
Thanks,

It would depend on the vintage of your MacPro. Do you have a Nehalem machine?
-
Yeah, Nehalem. Just came out of the box Thursday.

My Nehalem has Storage in slot 2, Kona in Slot3.

Switching to the NDD driver seems to have fixed the issue. Something I should have done before posting, but oh well. All good now.
Jeremy – I’m concerned that you and I heard different slot specs from AJA. Can you post a link the recommendation for slot 3 on Nehalem machines?
-
I don’t have a link, just an email from AJA support:
“Subject: RE: Latest Mac Slot configuration Intel Xeon “Nehalem” processor
>If they have a Kona 3 or Kona-LHi:
> Slot-2: Atto
> Slot-3: Kona
> Slot-4 SATA
>
> If they have a Kona-LSe or Kona-LHe: It must be installed in slot-2.”I have an ATTO R380 SAS card that requires 8 lanes. That’s why it’s in slot 2, and Kona in 3.

I see. So there’s no controversy that slots 1 and 2 are the “fast lane” slots, just that your storage solution seems to trump your Kona on which should get the fast lane slot?
