I did try to compress h.262 videos to h.265 and would expect, if I compress it to half of the size a comparison e.g. with vivictpp would give a result, that nearby no difference will be seen.

hwo do you come to the idea when you take a already lossy source and convert it to another lossy codec you won't see no quality degradation

common sense: each time you use a lossy encoding you are losing additional information and quality becomes worse
