Rendering 2 scenes simultaneously, dimensions problem

Hi guys.

I have a blender file w 2 scenes within it.

Scene A is setup to render at dimensions 960 x 1080
Scene B is setup to render at dimenstions 960 x 540.

I am using this node setup within Scene A so that both scenes render ‘together’ but output their respective .pngs to different folders when I hit render animation.

It works apart from the fact that Scene B is taking on Scene A’s dimensions.

Is there a way to specify it to stick to it’s own?

Thanks in advance.

Don’t bring scene B’s render layer into scene A’s composite space. Inside of scene B, activate the compositor and create a file output node there and it should render out with the dimensions you have set in scene B.
