Hello There!  
I would like to ask to you if threejs is able to postprocess video frame showed with a VideoTexture.  
In deeply, i would like to know if it is possibile to make ‘Transparent’ each white pixels of the video-frame.

The effect should be like the green screen of the 'Meteo Program"  
Thank you and have good work!

Hi!  
Do you mean something like chroma key?
