So i've got a question thats plagued me for a bit...

Lets say i'm rendering at 720x540, and i want to render extra pixels on the border image so that my render resolution becomes 740x560, however the same 720x540 image is contained within the larger size. There's a couple things this is good for, say camera shake in post, or what I'm doing: blurring an image without the edges of the frame becoming soft.

Thanks a billion!!!

Why dont you increase your resolution gate to the size you want?

but wouldn't that just render the same image only bigger? I need to render the same size image....just more of it, here's and example of what i need. Notice how the bottome image is the same as the top, only with extra pixels on the borders.

I’ve never done this but just applying common sense:

Divide the desired size of each side by the current size. From the two results use the larger number and divide with it the current focal length value of your camera. Use the result for your new focal length, which should zoom out your scene to fit in the new dimensions proportionally.

Increase your resolution and apply a smaller pre or post-scale to your camera.
