Different resolution in render than in scene Premier and Ae

Hello,

Got this weird problem..

My scene size is 2568x 768 px (yes its weird reso, we use pandoras box to map different sections of this resolution)

and when i render it out with premier the reso is only 1920 x 592?

What could be wrong with my rendering settings? Have double checed it many times.

Same kind of trouble with Ae, but when render it out there is those black blocks witch takes certain area of my reso?

P.s. I am new with Premier, why cant i change frame (scene) resolutions during editing? Is there some purpose?

In Ae its easy, just from comp settings..

Thanks,

Kalle
