If you use crossfade on 2 Layers, the first layer doesnt actually fade out. You can notice that if the second layer has some transparent pixel then u can see how the first layer just stays until it gets clipped away.

Can you post an example PSD file that exhibits the behavior?

Hi Moritz, the current behavior is As Designed by the engineer who implemented it.:

"It is as-designed. The cross-fade effect is mostly relying on Photoshop's typical blend compositing. In a cross-fade, the first clip is below the second clip in the layer order. The cross-fade effect gives permission to the clips to overlap (time wise) on the same track. The cross-fade is accomplished by varying the opacity of only the second clip. It is an opacity factor that is under the hood (it is separate from the layer's main opacity and interior opacity - in fact the three are multiplied together).The reason the opacity of the first clip is not varied is so that the resulting composite is fully opaque in the case of video or photographic layers. In general, with two pixel layers in PS, if the opacity is less than 100% on both layers, the resulting composite will not be opaque.That scheme doesn't work when the second clip's pixel content is not fully opaque, as this document shows. The pixel content in the second clip can't hide the content of the first one. There is a workaround: You would need to use the Opacity track and manually manage the keyframes.
