Luke,

There is no point in using Linux if there are no boards available. I am in the process of signing an NDA to use AJA’s Xena boards, but if there would be more cards available that are more easily accessible, linux-support would grow.
I hope you see the endless-loop problem here.

Even if you’d give away simply some specs so people can write drivers, that would be a big win. Right now, it’s just a bunch of DMA-space nobody knows what it supposed to do, and honestly, all that NDA-stuff, I don’t see the point really (but I have no problem signing them and not violating them). Maybe to hide the fact a Xilinx is easy implemented, fast and is cheap? You don’t need a DeckLink hardware-technote to know that.

I think you are better off with an AJA Xena card. Blackmagic doesn’t seem to want to support Linux at all…

Yes, but besides complaining, it does work.

I would throw away the reference thingy and lock the deck on the input, not on the reference… Our UVW-1800P nicely locks on the input, it can even lock on a VHS composite signal, better than any other VTR I’ve ever seen.

The cheap boards come with just BNC connectors. You’ll have to use your own Coaxial cables 75 ohm.
I *think* anything that comes with analog audio will have breakout cables since you cannot fit the big fat XLR connectors on a PCI board.

Hand pick is nonsense. They choose by assembly line. Chances they come from the same line (especially since the 24″ are still not commodity). What can really be different is the further quality of case assembly, like the backlight, enclosure and electronics. I’m pretty sure apple’s backlight is a lot better than DELL’s. Is it worth the price difference? Probably not…

Hello,

I have tried this version. It is definitely an improvement. Lowerfield DV plays out the decklink with the right field order. You can now capture DV lowerfield, edit it and export it to tape again without creating a sub-project and reversing field order.

NOT FIXED:
Of lesser importance of the above, the decklink shows garbage on its analog output when recording. As soon as the record-window is active, the decklink should show its input. Right now, it shows a field shifted down approx 1/5 of the image and the other field shifted down approx 2/5 of the image, resulting in a funny flickering image. I tried recording it once (looping the decklink output to another decklink system) but of course it cannot lock on such video.
This seems to be ONLY on the composite AND component output. SDI output is OK (but hooked up to the deck).

NOT FIXED:
When creating our own preset to record DV in upperfield, it still records in lowerfield. Premiere has everything right for FX to do upperfield DV, only BMD seems to have problems.

System:
HP wx8000
DeckLink Extreme
Drivers: 5.1.2

Why are you running Windows Server 2000 ? Most multimedia-server applications I know run either Windows 2000 PRO or XP PRO …
It’s not the OS that is important !

I think I’m pretty sure its not the card that compresses/uncompresses the DV stream… That would mean it should compress the DV after applying some effects and then uncompress it again in the card ?
Today pc’s are pretty fast and can well enough decompress DV in realtime and send it to the simple BMD decklink card.
