Blackmagic Decklink Extreme Pro or Aja Kona Card??
-
The only other firewire device is a Sony Mini DV deck, but it is connected to a PCI Firewire card, while the AJA is connected to the Computers firewire.
Regardless, we have 2 AJA’s on 2 different, but identical quad Core G5’s the dropping frames happens on both systems.
The mini DVD deck is only hooked up to 1 of the systems the other has no additional firewire devices.
We have even moved one of the AJA into our one of the edit suites (it is normally connected to a system that is dedicated for final output to tape) and it dropped frames in there as well and there are no firewire devices connected to the edit suite.

That should be Mini DV deck not mini DVD deck.

Steve these are the bare minimum machine that will work with the IoHD
My guess that you do not have them configed to handle the data being sent. I have not been able to playback 1080 ProRes on a Quad G5 –
AJa recommends that if doing HDTV with the IoHD you need a intel processor.

This is not an AJA IOHD, it is the plan old AJA IO.
It worked fine on our Dual Core G-5’s connected to G-Raids, but when we moved downstairs to the new facility and installed a SAN we started having problems.Again it really is not the AJA that is the problem. it has to be something on our SAN, but can not figure out what.
The AJA in question (or the Sony Mini DV deck) connected to a Quad Core G-5 or even a Dual Core G-5 (both connected via firewire 1 using the built in firewire port and the other using a PCI firewire card) will drop frames when digitizing to Raids 1 and 2, but when digitizing to Raids 3, 4, 5 or 6 it is fine.
So right there it says there is something with the box that contains Raids 1 and 2.
We have had out engineer triple and quadruple check every setting and the settings between box 1 (containing Raids 1 and 2) box 2 (containing Raids 3 & 4) and box 3 containing Raids 5 & 6) are all identically.
We have even tried changing switches that control the boxes, no difference.We’ve tried decreasing the port speed, anything you can think of we have tried it.
There is something with digitizing thru a firewire device (AJA or Mini DV deck) that will drop frames on only those 2 raids, but digitizing to the same raids with a BlackMagic has no problems at all.

Benjamin,
My experience with my BM Multibridge has, so far, been fine. It’s a good, workmanlike bit of kit that ‘does exactly what it says on the tin’… IQ is excellent, downconversion fine, and so far I’m happy. Yes, the Kona is slightly better built IMHO but you’d expect that for the price.
No experience of tech or customer support as it hasn’t broken. I’ve just stuck it in, turned it on and it’s been fine ever since… I think a lot of the differences in customer support between the two are maybe more marked on the west of the pond rather than on the east side anyway…
Just my 2 cents – I think you won’t regret either.

That is a very strange problem and one I’ve never heard of before, but definitely a conflict between Firewire and your SAN. We’ve never seen anything like that here for sure.
The Kona boards would remove this issue in your case since that would eliminate the firewire input for digitizing. Of course I would highly recommend the Konas over the Decklinks, but obviously you would need to spend more money to get the Konas.

Walter you are correct. It is very strange.
We have BlackMagics in the edit suites so to achive uniformity we decided to go with BlackMagics to replace the AJA’s.I’m sure the Kona card is an excellent device, but right now BlackMagic is what they want to go with here.
No saying what may happen in the future.
Thanks;

Sorry I misunderstood.
“We’ve tried decreasing the port speed, anything you can think of we have tried it. “
you do not say what type of SAN – fibre, sas or is it a NAS over ethernet.
chances are it is a cabling problem if it is fibre, those damned cables are very fragile and have been the bane of many installs
