New tool: Pixel Aspect Ratio Calculator

We've just released a new online tool on our site. Pixel Aspect Ratio Calc will take two image resolutions and work out the pixel aspect ratio needed to convert from one to the other.

It can also work out the necessary square-pixel resolution of a still image that will fit perfectly into the non-square pixel video frame. If you have ever tried to resize still images to fit into an NTSC frame, you will understand how useful this tool is.

Pixel Aspect Ratio Calc is available in two versions:
Pixel Aspect Ratio Calc (standard)
Pixel Aspect Ratio Calc (iPhone edition)
