I want text in the foreground with live video on it. Different live video in the background. How can I create this effect?

If you want to do this live you're going to probably need a serious hardware solution, which will probably cost an equally serious amount of money. Live broadcast/compositing isn't an area we specialise in, I'm afraid.

You will have to create the text in a serarate program, with an alpha channel. Then apply an object mask to the video you want to be in the text, and use the text as the alpha source for the object mask.

EDIT: oop, I missed the 'live' bit.

Thanks for the advice. Using the object mask worked fine to put video within the text. I also wanted different video in the background. Other than render the video-on-text and use the same mask to put video in the background, can this all be done as one project? I was looking at an iMovie tutorial where the mask and the text video and background video could be composited in a single project. Can this be done in CompLab?

Yeah. Just add the other video behind the text. It doesn't need to be masked at all, just place the layer below the text on the timeline. Check out this tutorial to get a better understanding of layers.
