I apologize for the long message but it includes some useful resources that attempt to clarify the problem. I've had this problem for a number of years and have yet to find a reasonable solution.
How do I get low latency video from an external camera into jitter (or any software for that matter), perform simple manipulations and then send it out to a projector?
I need the projected image to not apply a noticeable delay to the original source. If I am filming someone talking I want the sound coming from their lips and projected image to appear "live" without latency. I'm at the point where I'd like the image to be better than SD but will settle for anything.
A humble request in 2012 with such powerful computing power no?
I have a very fast macbook pro laptop with great graphics card and a thunderbolt connection and firewire 800. I also have a Mac Pro desktop.
I own a canopus advc55 firewire and have tried many many different cameras with it. I still can't achieve low enough latency. I've found that analog cameras seem to work better than digital cameras with analog outputs but it's still not good enough. I've tried the same camera setup in modul8 and isadora with similar latency results. I assume this means that it doesn't have to do with jitter or my not so great jitter programming.
It was suggested that the DFG 1394-1e was a good option but it is now discontinued. The Matrox MXO2 Mini seems ok but again doesn't solve the thunderbolt daisy chain problem.
So after all of this I still am left without a solution. It's frustrating because it seems like a simple operation that many people would want to do.
Are there any options left aside from getting a PC with the Falcon grabber?
