The Decklink HD Extreme is a PCI-Express card, not a PCI card. There are NO PCI cards that can do uncompressed HD that will work in a 33 MHz PCI slot (G4 Mac or first G5’s with 33 MHz PCI)
-
There are two main differences between the Pro and Extreme. First – the SDI-HD capture is limited to 4:2:2 in the Pro and 4:4:4 in the Extreme and the Extreme has a DVI output to monitor HD while the Pro has an HDMI which is not the same and doesn’t output HD content to an Apple 23″ LCD.

The only PCI-express were the G5’s sold first in late fall 2005. One model only before the MacPro. They consisted of 2.0 dual core, 2.3 dual core and 2.5 Quad core. All other models are either PCI or PCI-X.
As far as video cards go, there are still no aftermarket video cards for the PCI express G5 models to date.

Wouldn’t it be even nicer if the window under the cursor would always be the frontmost, automatically. To me, there are so many extra double-clicks onto a back window to make it active when editing.
At least that is what I would like.

When I got my Quad G5, I installed 4 – 500GB hard drives in a RAID 0 and verified that I was able to get over 200MB/sec transfers from the RAID. The, the first time I used MultiCam, it exibited the same jumpiness of the play head with 5 DV streams. I don’t remember what I did to fix it but, it should not be happening from one SATA drive as they are capable of at least 60 MB/second for each drive inside the G5.
You might try downloading the AJA Speed Test utility and check out what that tells you. http://www.aja.com
If you have the Decklink HD Pro card, then you will need much bigger drives in a RAID to get into that format. True, uncompressed HD requires nearly 200 MB/sec for each video stream.

Who supplied the FC card for PCIe. I know there are cards out the for $1500 from QLogic, but that’s a ways away from the Apple card for $599.

Keep it in mind that as we move from CRT based TV sets to LCD and DLP projection sets, that is going to change as those sets will not display NTSC blacks either. Eventually color correction will need to move to the same medium as we watch with for a more accurate color interpretation

I have 4 x 500 GB Seagate drives inside my Quad G5 in a RAID 0 configuration which is about what you might find with the external setup. I average about 230GB /sec on writes.
The SATA II 3.0 Gbps speed thing doesn’t really matter much when using 7200 rpm drives as they can’t even fill the pipeline with data enough to fill up 1.5 Gbps.
Another point to consider is that you wil be using the Apple RAID software to set up a RAID and that is subject to updating your operating system and loosing the RAID set. I use the HighPoint RocketRaid card which is hardware RAID setup, and will not loose the RAID set after a new OS version is installed.

That’s a good thought. Problem is that Apple still has not released the PCI-express version of the fiber channel host card . It has been listed on their Business Store as June 2006 for some time, and now it saying 7-10 weeks???

“” My MAC is a Pre PCI express Duel 2.5 G5. So no PCI express to connect the multibridge””
Am I mistaken, but I thought BlackMagic actually had a PCI-X converter card that could host that MUltibridge Extreme card on a pre-PCI express MAC?
