Re:Why are modern 50mm lenses so damned complicated? by pier25 on Monday May 10, 2021 @12:33PM (#27107866)
Another point to consider is that many 4K 35mm movies, are actually upscaled from 1080p or 2K scans.

Here's a good list to check whether a film is real 4K or not.

I've now remembered that the X-Men films from 20 years ago did look pretty good in 4K HDR. And apparently they are "real 4K". Also the 4K remaster of The Fifth Element.

Sorry, I was assuming we were not talking uprezing and true film scans. Uprez outputs can look disastorous as people tend to use a heavy amount of noise canceling. Bad temporal noise filters look so bad when you can see residual artifacts from 4-5 frames earlier. shudders. Or someone that did this to content that had a 3:2 cadence, and now want to restore to original frame rate even though the cadence is undetectable by filters. Select fields it is! Ugh. too many flashbacks popping off.
