  VHS-effects not compatible with roto?

  Posted by Christian Gundtoft on January 13, 2018 at 11:40 am

  Hi there, I have a top-layer in AE where I’ve “dug a hole” with rotoscoping. Underneath it I have some colorful material, that is visible through the hole in the top-layer. I would like to add a VHS-effect to top-layer, and be able to see the unaffected colors underneath. I use the Red Giant Universe plugin. Problem is, that when I try to add the effect to the top layer, the hole (that I would like to see through) gets black. This only happens with a few of the effects, not all of them. Anyone has a solution?

  Have you thought about creating an alpha track matte of the hole and then precomping, leaving the bottom layer outside of and underneath the precomp? That way your effect is only affecting what’s inside the pc and the the alpha track matte leaves a hole to see the unaffected layer underneath.

  If you can\’t tell a tale tall then it\’s not a tale at all.
