I masked an image in the UV/Image editor masking section. I then used that mask in the compositor for background replacement. However, the mask size seems to be different. Why is that? Here's a screenshot: enter image description here

    On the dimensions controls, the resolution size is set up at 50%, bring that up to 100% or add a distort-scale node after the mask and before the alpha over and set it to render size. –  May 06 '15 at 18:59
  • That was part of it. The ratio was also off. – AaronF May 06 '15 at 19:01

The reason seems to be that the render resolution didn't match up with the image size.
