  • After Effects fade-in/out of master composition

    Posted by Gcoffee on June 18, 2005 at 5:30 pm

    I’ve got the following set up:

    Composition 1:
    – Layer A
    – Layer B

    Composition 2:
    – Composition 1

    That is, Composition 1, which is made up of two layers A and B, is nested in Composition 2.

    Really all Composition 2 is for is to allow me to fade in and out the beginning and end of Composition 1. Problem is, when I do this (by changing the opacity of the nested Composition 1 in Composition 2), it seems to affect how the two layers in Composition 1 are mixed, i.e., the Layer B begins to show through Layer A even though when I’m viewing it straight in Composition 1, there’s no bleed-through of transparency. All layer blending is set to Normal.

    Any ideas?

    Transparency is not calculated linear in AE, so 50%+50% is not 50% overall transparency. Use Channel -> Blend from the effects to get linear dissolves.

    If you are just fading to black, what I always do is just insert a black solid on top of all my other layers and adjust the opacity on that.
