Is there? Can you point me to some discussion of this topic, since I strongly
disagree.
Noise that remains static in screen space when everything else is moving draws
attention to itself. Conversely, animated noise can look quite realistic
provided you have a high enough number of samples for it to pass for film-grain,
and if you don't have enough samples it's going to look bad either way.
Obviously there's no "right" answer to which is the best error (they're both
wrong!), but it would be really nice to have the ability to set the random seed
for the focal blur so I can chose if it changes or not.
Incidentally, I'm pretty sure Pixar use animated noise... though I've failed to
Google a reference for that.
