Isadora and Photoshop	Can't Post

Hi all

I'm quite new using Isadora, I've already searched in this forum but I didn't find solutions.

I'm using Isadora in a theatrical show, but in some parts I also need to use Photoshop, drawing live using layers and other PS featurings.
In a first study of this act, I used two computers (a Macbook Pro with Isadora and a Mac Pro G5 with Photoshop) and a simple mechanic video-splitter, choosing which source send to projector.

So this is my question: is it possible in Isadora to use an external source (the video output of the other computer) like whichever other video-source...?
(I need to use 1920x740 format, both Isadora and Photoshop)

I'm not sure I explained well.. sorry for my english!

thanks,
bonji

The only way you could use a computer as a source for Isadora is to convert the VGA output to Composite Video and then capture it via a Composite to FireWire or Composite to USB converter. But you're not going to get the resolution you're hoping for once you convert to analog video.

I don't have any other suggestions for you at the moment.

Best Wishes,
Mark

"v002 Screen Capture allows you to capture your desktop, or a portion of it to a texture and further process it. This can be used to bring in other applications output or windows as a source input to VDMX or other Quartz Composer compatible patch hosts."

Similar trick for windows, using Techsmith Camtasia. Camtasia will capture all or part of your screen and make it look like a video capture device. Isadora sees this fine.
If you have a multi montitor system and lots of CPU this works great, but it's messy to run it all on one computer. (still I do it sometimes)

The Canopus TwinPact will aslo capture a portion of your screen directo to DV, that you can use a a video input. It's $500 but the video is pixel perfect if you set the capture area to 720x480, no rescaling degredation.
On the other hand a $45 scan converter and a $45 usb capture device will do the trick if a soft image is OK.

Also if you get a Blackmagic capture card with HDMI input you can convert the DVI output of a computer to HDMI and capture it into isadora that way, it should look pretty much perfect that way as well. I have not been able to do this myself yet to prove it though.
