These days, kids identify them by the aspect ratio.
The real differentiator is pacing and editing.
I sometimes watch old movies and it gets infuriating how long they talk around the same fact that everyone already agrees on. Yes, he was killed with a knife because it’s still stuck in his head, now move on!
I do by audio quality. We currently live in the age of badly understandable dialogues.
Does anyone actually randomly send you nude girls? Genuinely curious
No. Doesn’t look like it.
This is actually because our microphones became better
Sure, microphones got better but there is more too it. One huge factor is the mixing for cinemas and not for home theaters or worse for TV speaker.
No, the video actually goes into that. Directors think it’s “more real” to have mumbled dialogues. But they seem to misinterpret that as “more mumble = more good”.
