Hi

Recently in a primary school class, I took my DV camcorder. A pupil
wrote a quick "news report" for English, then I filmed them saying it
infront of a plain black curtain. (not ideal as a blue screen
equivilant, but just a simple experiement)

In my video program, (Sony Vegas) I took out the black background, and
inserted a still image of a real TV news studio. I then added another
picture of a news desk infront of the moving-video channel. The
result, crudely, was very good. I didn't need to render the video
either just to watch a draft playback of it in the time line. (I did
render the segment so everyone could watch it full screen in good
resolution seperately.)

Now my question is - has anybody created a simple software program that
can display realtime DV input from a camcorder, and chroma key the
specified colour simultaneously? And preferably allow the user to
insert a still backdrop image?

Perhaps I'm asking the impossible from a small stand alone software -
but I figured if my software video editor can do it roughly, without
rendering it first - somebody might have implemented the same ability
into a specific program. BASICALLY it would be great to use
something like this, to drop the kids on camera infront of any
backdrop, for all kinds of inspiring purposes. And the idea of it being
realtime, to allow you them to see themselves and the rest of the class
view it as it happens. Also eliminating the time it takes for me to
edit and render it in full.

Or what's the cheapest piece of kit that could achieve this?

Thanks!
