I would need to use on my resolume arena a video input coming from an external computer (can be either mac or windows) throug vga.
Is there any way to do it? I've seen Blackmagic cards dont have the vga input..
I've seen the blackmagic cards (both the pci and the thunderbolt) but they don't have vga.
My system is:
Mac pro - lion
8 core - 16 gb ram
Resolume Arena 4.01
I controll Arena through a chamsys lighting desk trought dmx via Enttec pro.
What I would need the input card for is to get an input from a computer to display on a layer what it is sending on external monitor (mainly powerpoint or videos).
My main problem is that the sending comupter is going to change every time and I probably won't have much time to make experiment on the connections and compatibility..
the easiest way is so convert the VGA signal to something that the capture card can input, like HDMI, or Component. Using a device like a pro grade scan converter for example will give you component. Or you could get a really high end capture device that has 5 wire RGBHV input that is the same signal as VGA, then you just need a gender changer for your VGA cable.
you could use a scan converter, like an Extron VSC 500, 700, a Sony 1024, or a ScanDoPro series to convert your vga to video and use a video capture card. Or you could use a datapath capture card, I believe they make a model that takes DVI-A as well as D. Hope this helps!
VGA type signals would still need to be converted with an active device, you cant simply input a VGA signal into an HDMI port or an RGB Component input. There is a difference between VIDEO(RGB) and DATA(RGBHV), there is also a difference between DIGITAL(1s n 0s/on/off) and ANALOG(variations in voltage), you should do some reading and learn up on the subject, this is all very important stuff for a VJ to know. Using Resolume is easy and fun, but understanding how your system works from front to back is paramount.
