I hate to be the contrarian but I really hate blurry porn, sorry. I only watch something under 720p if it's unfortunately the only option, can't stand it anymore.
I think most would agree with you in theory, but the devil is in the details. Unfortunately, the majority of gigantic so-called "1080p" files look no better than their 720p versions, which often aren't all that much improved over their 480 base versions. Much depends on the studio, the cameras it uses, the locations it uses, and whether their file coders have the slightest clue what they're doing.
Bel Ami and Sean Cody do have a proper notion of how to provide true HDTV-quality files, at somewhat reasonable sizes. Corbin Fisher sometimes matches them, along with KB and a handful of others. The irony here is, if a studio knows how to do a decent 1080p file, almost invariably their 720p file gets within 90% of that quality at more reasonable size. Coding skill filters down to all resolutions: a really great 1080p will downscale beautifully to 720p for large screen TV viewing, and a 480 derivative can look fine on a tablet or laptop screen.
Many other studios have no idea what they're doing, can't shoot or expose worth a damn at any resolution, or can only make a passable file at 1080p at double the size of their rival studios. LE is the worst offender here: their 35-minute 1080p files are as large as an entire Hollywood movie DVD (3+ GB) while barely managing 720p resolution. Anything smaller from LE looks like mud (their 720 files look like old VCD, and their 480 files are dreck).
Titan Media has the worst cameras, worst coders, and worst directors: every damned video is shot 50% outside in the sun in a grove of trees and ferns that turn to unrecognizable block patterns even at 1080p (don't ask about the men: they look like indistinct Nintendo blobs). And for the love of life, somebody please clue Austin Wilde how to make a 1080p file that actually resembles HDTV, instead of being a 3.4GB abortion that looks like VHS-C from 1996.
The huge files are only worthwhile from a handful of studios, and not consistently. The rest? Forget it. No offence to the members posting 1080p files exclusively, but they should be aware they lose a lot of traffic from those of us who don't have the time or drive space to waste on inflated files that resemble 1080p about as much as I resemble Ryan Gosling.
