I'm trying to use a video and mask it with a noise image. The video and noise are working fine independently but when using [pix_mask] it isn't working (the original video looks the same). What might be the problem? Both files have a [pix_resize x y] of the same dimensions. I attached the file in case it helps.

@Yar You have a couple of [gemhead]'s
You could try fixing the rendering order...... see the [gemhead] help file..... as the mask needs to be rendered after the original for every frame (I think.... it depends on the effect you are looking for).

@whale-av I tried now both with 52 and 49 but it didn't work...
I'm trying to make the original video show only in pixels that are white in the noise

I looked at the file but didnt look at a video. I think you dont want to put "texture" before mask. it goes after mask. you would check the two image channels separately and texture them to a rectangle one at a time maybe and then change it to mix with mask object and then texture to the rectangle.
