Make sure you send video into the decklink also. The decklink won’t record anything unless you also give it video.

Wow, that is a feature I requested years ago. BMD never understood why it would be usefull.
I’m very happy to see they finally understood why we need it!-Yves

This is working perfectly with a leitch router. No issues.

As you have noticed, HyperThreading does not increase the speed for graphics intensive applications.
When an algorithm is correctly optimized for P4, your CPU at the subsystem-level should be in use for 100%, even more, HyperThreading makes sure that some realtime events are not so realtime anymore: an instruction can stall when another instruction is running on the other side of the processor. Remember hyperthreading makes you think there are 2 processors where in reality there is only 1.
Also, very often the limit on a CPU for graphics is not really the speed it can calculate things, it is the speed in which it can read/write (= memory bandwidth) data to/from the memory. Hyperthreading does not help this.A nice thing to do is to compare a dual xeon and a dual opteron. Also compare the speed in which it can just copy memory-data from and to the MMX/SSE registers.

Composite is analog. This will not work on an SDI input.
You should connect your house sync (also known as black-burst or BB) to the ref of the J30. If you don’t have house sync, don’t connect it.
The only thing you should do is connect SDI-OUT of the J30 to the SDI-IN of the decklink.-Yves

Yes.

You can plug your decklink into the RS422-port on the J-30.
You’ll also have to specify what video-input you’re using in the control panel.

What you might have in such a low-spec pc is that doing a RAM-preview might introduce flicker/black frames on the output.
Also, you will lack some CPU power to do complex stuff in AFX, unless waiting is no problem. And with that amount of RAM, you won’t have a big cache to do your RAM-preview. There is some tricks to extend it to disk, but I guess disk-speed will be slow too.Also, be aware that recent PC’s will be PCI-express, so in case you want to upgrade later, you’ll probably have to upgrade the decklink again.

We mostly run our own software on it, in keying mode. No clip playback, and of course, the graphics shown must not be too heavy, but that’s not a problem of BMD. That’s why we ship beefy pc’s for our applications instead of cheap ones.> – Can I successfully run the Decklink with Pshop CS1 rather

Yes. Even Photoshop 7.0 seems to run fine. This indicates that the photoshop plugin is clean and simple.> – Will the DeckLink run two PC CRT monitors (for workspace, etc)

Yes. Please not, you won’t get a realtime preview on the broadcast monitor, you’ll have to do a single step to show it on the monitor. A little script and put it on an F-key helps a lot.> – Will DL work with AFX 5.5 Pro and Combustion 3.0 just as

I don’t know about AFX 5.5, but it works for AFX 6.5.-Yves
