I just started using vvvv and still just see grey blocks and line and I would appreciate some input on which blocks I would need for the following setup:
2 capture devices, one gives an image with green (00ff00) background.
I want to key/mask that color and lay it over the other capture source.
Performance is an issue so I heard that you can do it with shaders to have great speeds.
I mostly dont have a clue how to start out, any input would be great.
