I rendered at 1080p. The background & the calculator were separate passes. I don't honestly remember what the render times were. The calculator up close was really slow, though, because it's refractive, reflective, has motion blur and depth-of-field turned on. I think those frames were around 2 minutes per frame. Once it's in the frame entirely, it probably was maybe 15-30 seconds a frame.

Thanks!
