Overlay mode for screen footage?

Wondering how to do this. I've got footage on a black background I need to have in screen mode, but then I want to take the resulting footage and use it in overlay mode for a reflection. Any thoughts?

Correct answer P.M.B

Just key out the black matte first. use a simple linear color key and then maybe a matte choker if you need it.

Sorry I forgot about this.

It's hard to say exactly what you're doing wrong, if anything.

I think you're just expecting AE to work differently than it does.

Either way a solution is to just stop trying to do it with a single layer.

Pulling it off with one layer would be clever but, pragmatically, if it's giving you problems just use two layers.

I guess it all depends on whether your goal is the process or the result.

As Mike_Abbott​said, 

Just use a second layer for the reflection in the glass and mask off what you don't need.

I would use a separate layer for the reflection anyway so I could use some mesh warp to simulate the refraction.

Thanks for keeping up with this thread. I plan on using two layers, but the issue is my footage is on black, so it needs to be in screen mode, but I also want that same footage in overlay mode to blend better with the counter. So, it seems I can't have screen footage in overlay any way I try.

Maybe I'm missing something here, but can't you precompose your screen layer and the layer underneath. Then use the pre-comp layer in overlay mode over another base layer?

Unfortunately not. Once I precomp, the blend mode of the footage is determined either by the precomp blend mode or the blend mode inside the layers of the precomp, but if it's the latter, then I can't change the precomps blend mode. Basically, I can't have two blend modes on the same footage, even if it's precomped. At least, I don't see a way to do it.

You need to turn off collapse transforms on the pre-composed layer.
