Painting on video

I belong to an internet community that is dedicated to flyfishing, fly tying, and rod building. We have a virtual classroom in which members with a webcam can broadcast lessons to other interested members. I have been using camstudio to capture the video from the virtual classroom and importing it into vms 9.0, editing it and posting to youtube and an inhouse video forum for archiving lessons. I was wondering if anyone knew how to paint lines onto the webcam image as it is being broadcast live to draw attention to special areas in the video. It would be like the diagrams that you see on NFL football games on tv. I know how to do it with recorded video, but I would like to be able to do it with a live webcam broadcast. Is this called rotoscoping, or is there another name for it.

Sorry can't resist.... I think it's called "mucho dinero".

But seriously, not sure but I found this:

I'm not sure I understand this ... aparently you want this feature so than anyone of your members with a web cam can do this .. supposedly while broadcasting live (and maybe being "on camera" at the same time)

Doesn't really sound doable.

I found the name of the effect that I was looking for. It is a Telestrator effect. Mucho Dinero is right for the device, but I'm looking at some freeware that claims to simulate it. I'll let you know if I find something that works. Thanks for the replies.

I found this freeware-VideoMage Producer 0.9- and tried it. It seems to work pretty good for annotating on live feeds from a webcam. When I tried it with my minidv camcorder with a firewire connection, I had to send the source to super webcam and then use super webcam as a source for videomage to get it to work. Videomage only writes to a video file, so I still can't use it in the virtual classroom feeds, but it is pretty good for making tutorial video files from live feeds or previously recorded video files. I'm still looking for something that will doodle on a live feed, but it could be that is not doable.
