Cross Fade Between Two Layers

[y030052]

There's a technique I remember seeing on a training video for cross fading between two layers and retaining 100 percent total opacity.

That is, if I want to fade one layer out and at the same time fade another layer in, just animating opacity will leave me with less than 100 percent opacity at the point where they cross.

I know there's an easy way to do this but can't remember what it is.

Can anyone tell me?

Thanks.

Hmm,

If you reduce the opacity in the top layer, the layer below will become visible. Don't change the opacity in the lower layer, keep it at 100%.

The situation I had when I made that post meant a standard approach like this was not possible. I needed to fade one layer up while I faded the other down.

I'm not entirely sure why, but in AE doing this with a simple fade results in an alpha channel with less than 100 percent opacity in the middle of the transition.

Anyway, using a Blend effect from the Channels menu seems to be the way to go....
