How to remove black background in Adobe Premiere?

[oxymoron1]

I'm using a transparent png logo which I want to animate (rotate in place), but when I add it to the timeline, black background is added. How can I remove the background, or retain the transparent nature of the png file? 

Thanks and sorry if it's a silly question. 

Edit: I tried the luma key, which I've seen suggested elsewhere, but it removes the logo itself and not the background.

Black is the lack of everything.  To change it you have to put something there that is not transparant.  Try adding a colored matt from the menu in the Project Assets section.

But then there will be color behind the logo. Is it impossible to export an animation without a background?

Perhaps the Chroma Key would work after putting what has the black blackground into the video.

You can export an animation with a transparant background (alpha channel)

Can you post a screenshot of the properties of this png to determine if the png realy has a transparant background.

I think this is what you're trying to do. How to add a logo without a rectangular background.
