<p>The answer is yes, video can be composited fast enough to be streamed live.  The tool that does this is called a switcher.  Typically a switcher introduces a single frame delay from input to composited output.  By connecting the output to a streaming encoder, you can stream out your live, composited video.</p>

You can also do it with software, for example Wirecast.

<p>I was watching a Twitch.TV stream of a panel of announcers discussing eSports live, and while all of the graphics, sets, backgrounds, lighting looked great, I thought it would be nice if the raw video of the announcers was also processed with composite editing, for a surreal, polished film effect. But I'm not sure: Can a video be composited fast enough to be streamed live, and are there tools capable of doing this?</p>

The answer is yes, video can be composited fast enough to be streamed live. The tool that does this is called a switcher. Typically a switcher introduces a single frame delay from input to composited output. By connecting the output to a streaming encoder, you can stream out your live, composited video.
