DVI/VGA screen capture
We’re trying to do screen captures of computer presentations at resolutions higher than SD, I know a screen capture utility would be ideal but the framerate needs to be pretty high and we haven’t found anything that could really cut it. What I was wondering is if there is any way of converting the DVI or VGA to HDMI and then grabbing that using an intensity card or does it only work with true video framerates and resolutions? Ideally what we’d want is an HDLink that could be reversed so it takes in DVI and spits out HDSDI, we could then goe straight into a decklink card or to D5 tape. Do the DVI/HDMI connectors on the multibridges only output or can they capture/convert input signals too?
Any suggestions or advice is appreciated.

I considered doing that as well but ran into a problem. Since computers run in square pixel mode and video is rectangle it will strech the video. I ended up using Camtasia (www.techsmith.com) for our computer applications and it worked great. You do have to have enough horsepower to run your app and do full screen grabs but on newer hardware we havn’t had any prolems with that.
I hope that helps a little.
