Chroma keying multiple layers with backgrounds?
on Sep 25, 2011 at 1:09:29 pm

Hi everyone :) I joined to find out if anyone can help me with this effect I am trying to go for in this video...

I want to create the paint like effect in this video:






0:18 - 0:21 etc.

I have tried to do this like this:

As you can see one of the ink effects I chroma keyed out the black and the inside of the white to give the desired effect, but I realised how will I get the other ones to work since they too have black backgrounds which I had to chroma key, and it made me think if this is even possible :S


I tried to chroma key the white ink splotch on top of the already chroma keyed one but it just had a black background from the already good looking chroma keyed one.

Is there any way to sort of work out which part of the black background this ink footage came with it needs to chroma key out for this different layer of it, or will I just have to edit them and export them in a way that all 3 of them are on the same layer / file?


Any help appreciated :)

Rather than trying to key out the white or black in your ink blot footage, you composite them together (in black and white) with a blend mode [link] like Add, Screen, or Lighten, then precompose them together [link] and use them as luma track mattes [link].
