Decklink & vegas 6.0 Question's

(1) Does Decklink Pro use hardware assistance in vegas 6.0 when you preview on an external monitor from the timeline?

(2) Do you have to use YUV Files with declink cards Or can you use DV, AVI, ect?

(3) Which driver version are you using?

(4) If you have a Decklink card do you need the software codec?

(5) will the decklink cards give you inproved frame rates?

I'm asking because I am not seeing any improved perfomace with my Decklink HD Pro Card. I've tried it in Sd and Hd. It previews but
no perfomance Inprovement .

The Spec. said : Real-Time Layers Video: 8
Graphics/Titles: 8 Hardware Real-Time Effects Color correction, transitions, video filters, speed control, chroma/luma keying, gamma correction, desaturation, brightness, contrast, proc amp and more

Thanks ZION

As far as I know Vegas makes no use of the hardware acceleration on the BMD or any other cards for that matter. Assuming that you're capturing from say SP or DigiBetacam you will get an improvement however as you're working with a less compressed format, that is there's less CPU power required. You do have disk arrays capable of keeping up though?
As to the driver question, I think I'm still running 4.8.1, I'll update and try again once I get over the current flood of work. To date I'm underwhelmed by Sony's lack of support for those of us using any BMD cards and / or anything other than 'consummer' formats.

So which app. uses the hardware Assistance?

I have a sata disk array.

Does this mean I we'll need to switch app to take advatage of the
hardware accelaration?

Oh! Boy!

Well a sata array will not cut it for HD, need SCSI arrays.
I believe PP will give you the hardware acceleration you need with the BMD cards. Just be aware that using that does exposes everything to hardware / driver problems and you only get acceleration for what the card supports, all else still relies on the CPU. Depending upon the nature of your projects hardware acceleration might have you jumping for joy or jumping out a window.

farss:
The blackmagic website says that particular SATA RAIDs will work with HD. Perhaps your blanket statement is inaccurate? (that no SATA RAID will work)

There are probably many SATA RAIDs that won't work.

Well the advice I got from my system integrator was I'd need SCSI RAID for HDCAM. PVCPro HD would be different.
Also I think you'll find perhaps they're referring to 10K RPM drives. If so that's pretty problematic as those drives are ver low capacity and you need a LOT of space for HDCAM, probably OK for TVCs but long form project I don't think so.
