AlexSLRLabs Please dont spend so much time in this "innovation". You cant compare a good lighting scene with a fake greenscreen compositing video. The extraction of the greenscreen or the FG-mattes for the actors are just a small part. After that "Roto-Part" you have to tweek the edges. And what is with greenspill? The color don't look right in the skintones. Ah and Greenscreen-Reflections will be a also a big topic.
And after the forground tweaking you have the match the perspective, lighting, colours, black and white values. of the BG-Plate to the FG. Trust me, at the end of the day you will watch a cheese Video, with no quality standards. Or you spend lots of money in the post-production.
