live drawing over live video
on Aug 3, 2010 at 11:21:48 pm

Hello!

I am a masters student in architecture and am attempting for a design paper to have live video feed, which is to be green screen footage, to be drawn over with the use of a waycom drawing tablet.

So.. i was wondering the best way to go about this?? i have managed to use the programme 'veescope' to get sucessful green screen footage.

now i feel i have to find a way to have a desperate programme running where the tablet is used to draw over a 100% opacity background and then have that somehow mixed over the green screen footage.

any help would be much appreciated!!

thanks,
Sam:)

The easiest way, you need:
1) Video Camera
2) Tablet
3) Switcher/Mixer with a luma/chroma key.

Simply feed the camera signal and signal from tablet into the mixer, set it up so that the writing is keyed over the video. Voila. Of course, mixers are expensive, but renting one might be affordable for you. Since it's live, make sure to choose one with a 2 frame delay at most.
