One of my personal favorites is 'a taste of egypt'. When I play the downloaded video on my AVP, it's incredible how much detail there is in just her lips for example. I've not seen any video on arporn that comes close to that level of detail, but maybe you can point me to one. I don't believe it though, since the bitrate of SLR HBR files is almost twice the bitrate of arporn, so I don't think it's technical possible what you're saying.
Going to play maries in my room now, I have the HBR here on my pc, dont remember seeing any pixelated hair
EDIT I just put on that video and I think what your'e talking about is the masking of the models. I've not compared the masking mechanisms between the two sites, maybe the arporn is better, never really looked into that. But I know for a fact that in terms of details, the SLR files are just substantially better. But maybe you need a highend headset to appreciate that, not sure if you can see it well enough on a quest 3.
EDIT 2 I quickly compared a few downloaded AR videos and in generally i think the masking algo is actually pretty much equal. For example that video I just talked about, "A taste of egypt", looks in my book not worse in terms of masking than those AR porn vids, maybe even slightly better. That maries video indeed has some masking problems.
Again, in this post I'm talking about downloaded HBR SLR quality. The streaming on the website doesnt even come close.
