3) add a channel mixer monocrome-> apply image ->layer channel(channel mixer) ->channel red copy
4) add another 2 channel mixers monocrome with green and blue masks

There can not be, because noone has your image.

It's all about the starting point. If you post your image and example of what you would like it to look like, we might be able to help you.

Not a video but this should offer some insight in using channel mixer plus other methods to produce B&W
