This may be a stupid question, but I just got back into pirating some shows and movies and realize that many of the QxR files are much smaller than what I downloaded in the past. Is it likely that I am sacrificing a noticeable amount of quality if I replace my files with the smaller QxR ones?
For example, I have Spirited Away from 2017 at 9.83 GB, but I see the QxR is only 6.1 GB. I also have the office from 2019 and the entire show (no bonus content) is about 442 GB, while the QxR version is only 165.7 GB. Dates are what they are dated on my hard drive, can’t speak to their actual origin, but they would’ve been from RARBG. (Edit to add: I also can’t really speak to the quality of the downloads, back then I was just grabbing whatever was available at a reasonable size, so I wasn’t deliberately seeking out high quality movies and shows - a simple 1080p in the listing was enough for me).
I did some side by side on episodes of the Office (on my PC with headphones, nothing substantial), and I don’t notice any differences between the two.
Thoughts on this? Are people better at ripping/compressing/whatever now that they can do so at a smaller size without sacrificing noticeable quality?
Your old stuff is most likely in x264 video codec, while, especially at the higher resolutions, x265 / HEVC and in rare cases AV1 are the standard today. But it also depends on the specific release how many streams (like audio tracks, subtitles) are included
Be warned though, some x265 stuff out there, particularly at 1080p and lower, is a reencode of a x264 source file. So lower filesize, but also slightly lower quality. Scene regulations say only higher resolutions should be x265.
I still prefer it, HDDs aren’t free and I personally really can’t tell the difference (my TV kinda sucks anyway)
