How do I apply a cross dissolve to a clip that has a mask on it?

[edit58989569]

I have a clip that has a mask and a cross dissolve.  This cross dissolves also dissolves the mask shape outline making the image black before it fades in. I tried nesting the clip, but that didn't work either. Is there another way to do this? 

Thank you!

That is what a cross dissolve does: Dissolve.

what are you trying to achieve?

Post screenshot entire UI showing the timeline, clip selected with mask, effect controls and program monitor.

I want everything that isn't masked to cross-dissolve. Does that make sense?

I understand, that but if I dont know what effect, what mask and how your timeline looks like I cannot give an answer.

But most likely you need to duplicate and superimpose the clip with the mask and cross dissolve the underlying clip.

This is an old post, but for what it's worth, I applied a film dissolve transition to the lower/original clip only. It worked for me.
