Hi, I'm turning me crazy, I tried to do this tutorial of twixtor:
But I have a big problem, I don't understand what she is saying at the minute 3:36.
She says:
"we render the matte out, and we just bring back as a layer"
I look for other tutorials, for the shortcuts in japanese in AE, for tutorials of roto brush, but I don't know how to "render out the matte".
I tried to duplicate de layer, delete the rotobrush effect in the main one, and select the layer with rotobrusk like the mask, but I didn't work.
Please, help! :(
