Same footage 2x, one w/alpha, one without?

I'd like to layer the same footage on top of itself, but have the top layer use the footage's alpha channel, while the bottom layer ignores the alpha channel.

How would one do that?

Setting Interpretation globally affects BOTH Layers, I want to have one WITH, one WITHOUT.


THANKS!

Are you looking to have a Background color on the bottom layer? You could add Channel -> Solid Composite to the bottom layer.

2 layers, same footage.

There is color information in the alpha area. I want to use that color informaation as the background. So, the bottom-most layer will not use its alpha, while the layer above, same footage, will use its alpha.

Okay I just tried this, I imported a graphic with an alpha channel and left it alone. Then I imported the graphic again, so I have two copies of it and set the interpretation to ignore. Same video with and without alpha channel. Is that what you are trying to accomplish?

So simple? Dang! So, just import it twice, with different interpretations.

You can also duplicate (cmd-d/ctrl-d) your footage item directly in the Project Panel and change its interpretation. You can even rename the individual instances of the footage item in the project panel to keep things clear.

Or you can duplicate the layer in the timeline and apply a Channel > Shift Channels effect with Alpha set to Full On.

Geez Darby, now I feel dumb for only coming up with one solution.

Haha! It's an Adobe application, there are always 10,000 ways to do it. Even keeping track of a fraction of them takes up a good bit of brain space.

I'm seriously afraid that when I get into my rocking chair years I'll be mumbling about blending modes and matte layers to my grandchildren.
