Hay All, I need help, I am currently learning Nuke, Already working in Fusion.
I have tried to Use Garbage matte, in Nuke, but didn't find any option to add mask.
so i tried to use the roto node, but it didnt worked.
I have attached few screenshots, its getting confusing.
It was easy, in fusion i can just use the Bitmap Node to make black transparent.
The first image is output of Keyer
The second one is i added the roto node, and gives this output, i tried to invert the mask but it not working.
And this is how it looks.
So please help me to understand this .
