live video?

ok, this is a tricky one....

can anyone think of any way to import a live video signal onto the stage... i doubt it's even possible, but maybe there's some kind of special live streaming format i don't know about...

or maybe there's another way to achieve that effect within the computer. for an experiment i need to draw over live video, and if not within moho, then perhaps there is another program through which i could dissolve between 2 open apps?

it's a longshot.

Don't know if there are. Why would you want to use a live stream?, wouldn't recording the stream first and then import that file do?
You'd have to be pretty quick to draw over live video...
Oh, I just came to think about a thing, find out what kind of software sports commentators use, they draw over live streams sometimes.

What you want is some kind of "genlock" device that can overlay graphics onto a live signal. There not as common since non-lineair editing has become standard. I do not have current knowledge about the equipment unfortunately, so I suggest you try googling a bit. In short, "(chroma)keying" is the technique of removing part of the foreground and show the background through that, "genlock" is the way to overlay graphics onto the background.

Good luck,
