light grey border on jpeg renders

Hello all,

This is my first post in these parts. I’m a graphic artist working for a mapping software company in fredericton, new brunswick.

Anywho, heres what I’m pondering. When I render jpeg images, I always seem to be getting a light grey border around the edge of the image. Does anyone know how to disable this?

Of course the obvious would be to crop it manually, but many frames would be a major hastle.

If anyone knows how I can remove this, I’d be very appreciative to find out how.
