I've been trying for hours to remove my white (well, grayish white) background from a video, and I thought you could remove it with keying nodes in the compositor (cycles). I managed to get somewhat close, but it still has pieces of white, and it affects the colour of my sunglasses. I've tried tutorials meant for green screens, keying/chroma/difference/luminosity nodes, but I just can't figure out the right settings. Core matte mask helped a little, but made it impossible because my body moves in the video. I played around with the keying colour a lot, and nothing seems to help.

Is this possible or is a green screen absolutely necessary?

I've attached the .blend file with a screenshot rather than the whole video due to file size, but I imagine it's the same principle.

Here's a screenshot of the original image:

Here's the node setup:

Thanks in advance!

as you can see, with this setup you get pretty far.

Of course you should mask out roughly your body before, so that it won't "hurt" your face ;)

  • $\begingroup$ Thanks! Seems so simple and effective. Only thing is, I move in this video...if I mask the body, how could I make it so that it doesn't cut out when I move? $\endgroup$

  • $\begingroup$ If you move you have to use the tracking feature of the video sequencer - but this is a second question...😉 $\endgroup$
