Deckling in PCI slot on MAC
What happens if I have deckling HD pro (single link) set to usuall PCI not PCI X. Because I have a Huge raid, which also is connected to my mac with ATTO SCSI adapter which also requeres PCI X and my mac only has one PCI X slot. Does it mean that I am limited in working in HD?

leave the UL4D for the HUGE in the PCI-X slot and put the BMD in slot 2 or 3, you will be fine.

I don’t understand. I read in blackmagic design manual that decklink card must be installed in 133mghz slot, and ATTO also requires 133mghz, but my MAC has only one PCI with 133mghz, so what should I do?

Hi Levan,
It is stated in the manual that the top slot is preferable. This is because that 133Mhz slot uses its own dedicated bus unlike the bottom 2 slots that share one bus.
Use the top slot for your ATTO card and one of the bottom 2 slots for the DeckLink card. Make sure you don’t have any other cards sharing the same bus as the DeckLink card.

Sorry for being so picky, I just want to make sure I do everything ok.
So if you look inside my mac there are 4 slots, the top one is 133mgz, and this is where I put my atto card, ther bottom (the last one) is for my video card, and at this moment I have my Decklink card pluged to the second slot from the top. So there is one slot betweend deckling and video card.
Is it right?
:*) thank you for your help.

Hi,
Yes, this is perfectly OK.
Slot 1 is the AGP slot for your monitor board;
Slot 2 is the first of two shared 100MHz PCI-X slots;
Slot 3 is the second of two shared 100MHz PCI-X slots;
Slot 4 is a 133MHz slot, not sharing with the other two PCI-X slots.If you place a board in the 133MHz slot, it can’t be influenced directly by placing a board in one or both of the 100MHz slots. If you place it in a 100MHz slot, best is to keep the other slot free.
The bottom line is this. If you place an HD board in one of the 100MHz slots it will run fine. However, if you place a second board next to it, in the second 100MHz slot, and this is a ‘slow’ (PCI) board, it will slow down the 100MHz bus altogether, and by consequence have a negative effect on the functioning of the faster HD board.
Hope this explains,

Theo, Thank you for confirming, now I know that I have the Decklink card pluged in correctly, but here is another question, I have posted it separately, but nobody replied.
When in sequence setting (in final cut) I use blackmagic in compressor (quicktime video settings), in my RT extreme menu, all the setting disappear, I only get option “Play base layer only”. and as I understand this means that I don’t get the real time in Final Cut Pro. So why is that?
And also can you tell me difference between:
Blackmagic 10 bit (DV10) and Blackmagic RGB 10 bit
or
Blackmagic 8 bit (2Vuy) and 8 bit (DV00)is blackmagic RGB 10 bit better than uncompressed 10bit 4:2:2? Please consider, that I shoot on 35mm film, than telecine it at 1920X1080 resolution, and after editing I sometimes print back to film. So is blackmagic good codec for using this way?
Oh, and I have blackmagic HD pro (single link).

Hi,
RT Extreme is a technology developed by Apple Computer, and you only will get the acceleration when using the respective Apple codecs. If you choose an Easy Setup for 8bit or 10bit uncompressed video, you will automatically get sequence settings using the Apple codec and get the acceleration. There’s no need for you to go deeper down and change the codec and we do not recommend to do so unless you know exactly what you are doing and why you are doing that. Quality wise in the Sequence Settings there’s no need to jump from the Apple codec to our codec.
The RGB10bit codec can contain RGB 4:4:4 sampled data, whereas the 10bit YUV codec is used for YUV 4:2:2 sampled data. When you have a DeckLink HD Pro 444 (Dual Link) board you can import RGB 4:4:4 data, for instance from HDCam SR, and you will need our RGB codec to write to. I understand you have a 422 (Single Link) board, so there’s no need for the codec here. You write to a 4;2:2 codec here witout any loss (and can go to RGB color space after that, for instance when going to After Effects or Shake).
All your codec questions are answered in our support notes 33 (Can I use CineWave

Thanks for info, but still another question :*)
So is Blackmagic 10 bit RGB mean that it is uncompressed 10 bit 4:4:4?
If so, will decklink HD pro with dual link make any difference for me in terms of working in real time of uncompressed 10 bit 4:4:4 or is it just for capturing and writing only? Meaning that does it have any render acelleration?
Sorry if these are stupid questions.
