Hey there,

I´m want to have a mask from one color.

Here one example:
I have one video with a red shirt.
I use "color pass" to pass the red color. Everything else become grayscale.
Then I want a mask that are created from the red color so there are only that shirt.

Hope someone can help me.
Thanks!

Hey Axel

At the moment, Avenue does not support making masks from moving footage or live keying. Depending on the footage, you could use a Add/Subtract filter to further single out the red though.

Hope that helps.

Hey Joris,

thanks for your answer.

I tried "Add Subtract", but it will fill all parts of my clip.
Do I something wrong? I have a person with a red shirt, who
dances and I want to delete everything except the shirt.


Bye, Axel

Hey Axel

It all depends on the specific footage you're using. If you've managed to filter out the red using Color Pass (do you mean Pixel High Pass btw?), maybe you could use Exposure to change the bright red parts to white, and get rid of the gray. Then you could use a multiply blend mode with the effected layer on top of the original layer to use the white parts as a mask. In general this sort of stuff is notoriously hard to do, even in high end expensive compositing programs.

Good luck and hope you find a way!
