[David Cherniack] “Degradation after 5 generations isn’t any meaningful take away at all. The only meaningful degradation is that after one or two generations. Do that test and there’s something worth considering.”
Measuring or viewing degradation over multiple (5+) generations has been a meaningful way to gauge codec’s “lossiness” since the beginning of digital video and graphics.
What’s meaningful to you, is not necessarily meaningful to others.
