Perhaps, "absense of artifacts"? And not just spatially, but temporally
as well. For instance, does the picture smear, streak, or strobe? Does
it cause unflattering effects? I realize this doesn't really answer your
question. For stills, we have picture quality signal to noise ratio,
correct? Perhaps, could there be a motion quality signal to noise ratio
that can be measure?
