Bending an image to fit in a green screen

[BSBLLC]

Hello! I downloaded some stock footage of a billboard and am needing to bend an image to fit in the black space, but the billboard is on a corner. I tried using corner pin but I couldn't get it to pull up in the middle at the top. 

Is there a way to do this in Premiere so it fits the black space in the attached photo? Thanks so much!

Do it in Photoshop and then bring the image into Premiere Pro.

Thank you!

That's a job for either Photoshop or AfterEffects for certain.

I had a look at your problem. I took a billboard still and croped it into two stills about 1/3 and 2/3 the width, I then used corner pin to place the two pictures on each edge of the corner.
