How to add bleed to render (additional space, extending the rendered area)

Hi there,
I have to redo some renders.
They should cover the same area and not change in resolution or position - I need only to see 50% more of the scene on top.
Is there a way to do this with vray for 3dsMax?
(I know a way with Vray in Maya to extend the rendered area, but not in Max).
When I change the image dimensions it changes the camera view, too, which isn’t good.

Thanks

It’s called overscan, there should be a ton of scripts around that allow you to do that.
