Actually shots like these https://caps-a-holic.com/c.php?go=1&a=0&d1=14854&d2=14678&s1=154639&s2=151989&i=5&l=0 and chromatic error causing color to bleed on a part of the guitar. the grain reduction happened because hdr was done incorrectly on all three films valeyard said. also the thread starter is a little wrong. the only films that had it done the badly was back to the future 1 and 2. three has it noticeable in two scenes which yes I still think it should be fix but it isn’t as egregious. Back to the future trilogy deserved the same care as the karate kid trilogy actually more so because the third karate kid film isn’t that great. yes I know different studio. all three back to the future films are fun I heard the encoding might be the issue with the uhd bttf trilogy set.
