2 chroma key simultaneously

[vjastral]

Greetings!

We do love Resolume and its flexibility, but at the moment I am struggling with chroma key setup. We have 2 objects for visual effects. One is the green background and the other is an actor with a blue costume. Effects must be separate. For example, 1 video clip is in the background and another clip is filling the costume. I know it's easy for someone but I can't figure out the needed result, as a fact I have all kinds of effects but the one I need I can't get really. The closest I could see is and transparent background but it's not actually on the back the clip is just transparent. I have tried to mask the images, chroma keys on clips, layers, and composition, but could get the result ( All I see is that I can use only 1 chromakey and once. How to achieve different clips with different background chroma and foreground? Please help.

Thanks in advance!

Could you upload a sample of your image you'd like to filter?

Also, you'd like to place a video over the dress, and another over the background?

Like this?

Thanks for finding time to replying to this post, Zoltán. It seems that your picture fits my issue

[Zoltán]

Cool, so what I did is just a regular chroma key on the layer 2 clip,
and then another one on layer 4, to get the background out,
brightness contrast to make the image black,
Invert RGB to make it transparent + white,
another Chroma key to remove Alpha.
Then invert RGB again to flip black with white.
And use layer 4 to mask one below.

Thanks, very much, but somehow it didn't work on my side. I have attached photos. What is the point I am missing Much thanks in advance

The effect stack should be on the clip in the masking layer.
The masking layer should be the top layer.

Ok, thanks, I found that mask function Layer -> Mask mode and made the first clip masked as on your screenshot, but I guess that somehow I don't have composition+clip+layer stack as on your screenshot and I don't know why Also, there is a white background as you can see...

Finally, I achieved the result I needed thank you very much for this! My last question is about your screenshot, you do have composition+clip+layer... I made a green star on me to mention.. how did you make this and what are the advantages. Wish you all the best!

Nice!

You can rearrange these panels by dragging on their name.
Then if you like a layout, you can save it in the View menu - Layout.
You can also disable and enable panels in View.

BTW, if you're using a green screen already, and want to mask the person completely, I don't think the person needs to dress up in blue necessarily. You should be able to separate the person with a combination of some effects, like the levels, invertRGB, and then colorize it, to then chroma key.

Thank you very much. Wish you all the best!
