about AspectRatio (Transform)

For changing the ratio and doing anamorphic rendering, the AspectRatio (Transform) node was invented. Its quite similar to Scale (Transform) , but it avoids some of the extra divisions upstream. Just enter the magic numbers 16 and 9 into the right inputs and connect it to the Renderer (If you use a camera, connect it between Camera and Renderer).

FAQ

Why do I sometimes need to swap height and width?

Basically AspectRatio behaves in the intuitive way when used to transform Quads - So if you connect AspectRatio to a Quad (and have a square Renderer) you will get a rectangle with the expected aspect ratio. On the other hand, when connecting AspectRatio to a Renderer, you would map square content to an rectangular screen, which is the inverse process. You could use Inverse (Transform) for doing that, but for some reasons deeply rooted in linear algebra people can also change width and height and get the inverse matrix directly. Which is easy to do, but always counterintuitive.
