i know the core library can make video record with movieMaker  http://processing.org/reference/libraries/video/MovieMaker.html

I'm interested in this as well. I've bookmarked this discussion from the old forum on syncing audio on video
http://processing.org/discourse/yabb2/YaBB.pl?board=Sound;action=display;num=1174169711

Although this is useful it's kind of overkill for some situations because I can already run everything in realtime without problem. Ideally there would be some kind of addon (class) for moviemaker that automatically adds the audio to the movie once it finishes. To save everyone the trouble of manually syncing afterwards, because this can be quite cumbersome sometimes. I've also tried fraps, but the sounds quality was very bad and more importantly the output was a huge avi file.

There are no effective way of doing this from what I have learned after searching for information about it.

Sucks...

I know this is an old post but for those that come to this post from a search engine there's a way of recording both audio and video (from a webcam) using the third party library GSVideo: Record video and audio from a webcam with GSVideo
