AJA KONA 3 & MAC PRO DROPPING FRAMES

Dropping frames is solely created by data throughput, has nothing to do with the Kona board. It has everything to do with your media throughput from the hard drives.

Has anyone any thoughts? This has got me scratching my head!”

You didn’t say what media storage you’re using.

Will all do resepct, this is not entirely true. If you have the wrong easy setup chosen (say trying to play an uncompressed timeline when the Kona’s expecting a dv timeline) you will most likely get dropped frames no matter how fast your drives are.

Creative_Tech, try selecting the proper easy setup for each timeline and retry. Also, you need to setup your PCIe slot configuration according to the Kona specs outlined on their website.

Jeremy you are absolutely correct! Didn’t even think about that.

And along those same lines, ensure that you have your Canvas and Viewer set to “Fit To Window.” If they are scaled up beyond what either can show, you can also get dropped frames that way too.

If this gentlemen is using an Apple XServe RAID, (he did say he had a FC card, so I assume that he has an XServe RAID, but I could be wrong) –
he MUST turn off CACHE FLUSHING in the System settings of RAID ADMIN, or he will get dropped frames.

But he has not responded to what type of storage he is using.

He said some sort of SAN and firewire drives…?

[Bob Zelin]

You write –

Tried to playout a simple DV sequence over SDI using AJA KONA 3 – PAL 8 bit to DV from a firewire drive not involving the attached SAN in anyway – DROPS FRAMES every 10-14mins

REPLY –
Firewire drive? I hope it’s a firewire 800 drive – you aint’ gonna get nothin from a firewire 400. Is there anything else on the Firewire buss? Do you have multiple fw drives looped together? What brand of Firewire drive ?

on the SAN – what SAN – Apple XSAn, MetaSan, Terrablock, EditShare ? Details please !

We’re having the same issue.
Macpro 1.1 2×266- Intel
4 gigs of ram
FCP 5.1.2
Kona 3
Atto FC-41ES
6 terbyes of fiber (Terrablock)
We still have dual 2.5’s running Kona 2 same drive set-up with no problem. Most of our work is 1080i 29.97 or 25. We have followed Kona’s specs.

What has Facilis had to say about this issue?

Did you setup your PCIe slots correctly?

[Rob Tobin]

Yes, I think that’s the problem… I just got off the phone with AJA. I’ll re-post if it works.
Thanks
