I have a image which has full HD resolution (1920x1080) and I want to use it as background for my animation without decreasing the resolution. My animation is in HD resolution (1280x720). The background is added using compositing with nodes. When I render the animation Blender cuts of the edges of my background image so that it fits the animation resolution.
Is there a way to keep the resolution of the background image but render the animation with another resolution and still have the whole background image in the final animation?
