I tend to notice the drop in quality in more slow scenes since there is more time to notice it. Though very action heavy scenes do suffer if the encode is bad. It would be really nice if we did see more shit in 60fps though. I understand what lots of "but 24fps is more 'cinematic'" mean for some kinds of shots/movies. But after being so adjusted to 60fps and higher (even if shit is interpolated due to having had a "120Hrz" TV since like 09), shit is much much cleaner. The "soap opera effect" is a real thing, but it kind of just stops being an issue after you get used to it and see the benefits of clarity and smoothness. And it is much more like how seeing shit in real life.
I have been having a real hard time going back to watch movies and especially animated media. Like a panning shot in an anime just looks so damn jittery. It completely takes me out of the thing I am watching as it can make me feel a weird kind of nauseous. Lots of regular movies and shows also do this. Some of it might be due to some stuff that was shot in early digital making it worse. But it does happen with stuff shot on film too.
Just really sucks that the industries seem to go out of their way to make it hard for studios/film makers to try weird shit now that we have it. Like I would love to have the 44fps version of The Hobbit since I missed being able to see it in theatres. But the home releases are all set to traditional speeds. It isn't a limitation of the Blu-rays themselves from what I understand. But the players tend to only allow 24/30fps for playback. Though I would love to be wrong about that. But still just artificial shit stopping potential advancements (or at least fun efforts to try shit). Those Spiderverse movies being done in layers of different fps rates is an example of trying some weird shit that was dope.
It really depends on the media and my level of interest in it. I was only bothering to try and get 1080p copies of stuff I liked due to only having a 1080p TV for so long. But I did make efforts to get 1080 where possible (and based on my drives at the time) even before I had a HD TV and the only thing I had to actually watch that resolution on was my laptop. And that was because I wanted to make sure I had (at the time) the best copies of torrented encodes of stuff I really loved and would want to look good later. But I got a 4K HDR TV a few months ago as my 13yo 1080p TV started just giving black screens on all inputs. And while a lot of things are fine, the limitations of the encodes are showing much more.
If I am just checking out something that I have heard about or was told to check out by a friend. I might just grab a 1080 or even 720 copy since they are often the top seeded results. Then go back and find 4k copies if I really get into it. Though my main issue today is similar to back when I was using my laptop. Storage space. I started ripping my Blu-rays and I am the worst about dealing with compression stuff. So I really really need to get on making that media server I have been "meaning to build" for years. Get some 18TB or 20TB drives and RAID the shit out of them for redundancy. lol.
