This is out of my area of expertise a bit, but digitization quality loss often depends on whether you quantize things, at what level of fidelity and also what kind of transformations you apply (stepped discrete or continuous for instance).

Consider how music production is often done on audio recorded at a higher sample rate, so when effects are applied artifacting is reduced for the eventual export sample rate. For video, one analogy is recording slow-motion shots at a higher framerate rather than slowing down regular footage.
