AJA KONA 3 & MAC PRO DROPPING FRAMES

[Rob Tobin]

The problem seems to be fixed. For those experienceing the same thing… install the Kona in slot three and use the PCI-E expantion utility (new for Intel-Macs) and make sure slot 3&4 are running at 4x install storage host card in slot 4. The install instructions on the Kona site needs to be updated as it indicates that you can install the Kona in any open slot.
Thanks for the help.

Hi everyone thanks for your input – sorry for the delay on relying – been rather hectic today! To clear up a few points:

I discounted our SAN storage (XSERVE with ADTX STORAGE) as the root of the problem because I tried connecting up a Lacie 1TB FW800 drive loaded with DV PAL rushes and played out a DV PAL sequence using the Kona PAL-8 Bit DV Easy Setup and I still got dropped frames aprox. ever 10-14 mins. The SAN was in no way part of the system…..

I also played out 2 30minute DVCPro HD sequnces from the SAN to a Panasonic AJ1400 deck today over firewire and not a single problem….

So to recap ANY playout over firewire performs GREAT!! ANY playout over the KONA 3 interface drops frames ever 10-14mins no matter what resolution.

As far as slot setup in my MAC PRO machines:

Fibrecard & KONA card in PCI slots 4&3 running at x4

Slot 2 EMPTY

Slot 1 Graphics card running at x16

I believe this is as per KONA recommendations….this is the second from top PCI EXPRESS profile listed in the expansion slot utility of the MAC PRO machines……

So, anyone any the wiser?!?!?

Has the firmware been updated on desktop?
which version of QT? should be 7.1.3

UNinstall the Kona drivers using the uninstaller in the Kona utilities folder. Then reinstall.
This is the only way to assure the update

Creative Tech,
Finally found the problem… May be your issue as well. Thanks to the AJA support team I found that there is a new tab in the Audio/visual settings (new from version 5.0 anyway) that allows you to set seperate outputs for edit to tape function. Make sure this is checked and set to the same format of your sequence. I guess this is for users using cinema displays for monitoring.
Hope it helps

Hey Rob.

Many thanks for that….I really thought it would do the trick – sounded logical and everything…..however it didn’t! Back to the drawing board I guess. Pleased to hear the guys were helpful at KONA. I’m ringing them this afternoon..I’ll report back.
