This could apply to Giorgio or any studio on here (I was tempted to post in General forum, and might later). But Giorgio, have you ever considered to moving to a 60kbps bitrate for 4k videos? It looks absolutely amazing. You can see skin and cum and other details and much granular detail if you're on a nice 4k OLED or similar TV/monitor.
I'm not here to plug a certain studio because I actually can't stand their male actors and most of the sex acts, but I find myself downloading their 4k files (which are admitedly about double AVIDS size) just to see the 4k, 60 KBPS h(high bitrate), 60fps action. The sites rhyme with "Glacial Misuse" and "Dreddo Daggers", and you have to pay extra just to have access to the 4k portal. I'm not sure what camera they use, but I can tell you with that bitrate and file size, it looks noticeably more detailed and lifelike than any other 4k content, again if you have an OLED TV/monitor that can actually show it off.
Even if you offered the traditional smaller 12 GB files alongside the new ones (they're like 25-28 or so if I remember right), that would be awesome. I'd pay more for the scenes.
