Philip Thanks for responding, Philip. I appreciate that we already got 2 SLR reps looking at this thread =).
I totally understand about keeping 21Mbps for the streaming option. And I agree that 120 Mbps is solid for Original files.
Philip you should not see any degradable quality in lower bitrate file. If you can spot it, please provide the screenshots and I'll take it from there.
TLDR2: if you can't find a difference don't waste time/money/traffic downloading original
Even before I took these screenshots, I could already tell you that I can 100% tell the difference. Even between 60Mbps and 21Mbps I can tell the difference. That is why previously I always downloaded the 60Mbps SexBabesVR files over the 21Mbps versions. Maybe majority of users cannot tell, but then again, I'm not so sure about that.
For many years, I watched VR on a Samsung S8 Exynos with GearVR, and I was already clearly able to tell the difference for the SexBabes videos mentioned above. Now that I'm on a RTX 3080 with Pimax 8KX, the difference is even more noticeable.
Also, everything you see in these screenshots are amplified when viewing through a headset, since VR players zoom in the picture to fill the LCD panels in the headset. So just know that even though the differences are subtle here, when viewing in VR and these images appear inches away from our face, it is definitely noticeable.
And finally, remember these are just screenshots, so they only tell half the story. When viewing this in motion, the lower bitrate is also even more so degraded (in comparison).

(Best way to compare is to open each image in a separate tab and tab back and forth to see the differences)
(1st picture is Original at 120Mbps. 2nd picture is Rendition at 21Mbps)
Witcher Ex 1
Notice the bumps on Whitney's forehead area, her eyes, and nose, etc.

(Rendition)
Naughty Dorm Ex 1
Same with this, look at Melody's facial features, and skin textures.

Naughty Dorm Ex 2
This one is really obvious when looking at Melody's face.

Naughty Dorm Ex 3
Compare Kenzie's and Melody's faces between the two images. The detail is crystal clear in the Original and very soft on the Rendition.

So yeah, to me, it is a very big difference especially since closeups are so important in VR. And I just want to reiterate, I noticed the differences between the two versions even before the screenshots. I remember the first time I downloaded the Witcher scene and the Sofi Ryan scene, I was not happy with how they looked, so I downloaded the Original file to see if there was any improvement and I instantly noticed the difference.
So, I hope that helps support my point some. I know there are many reasons why you still may not want to offer a higher bitrate, but just know that the end result is definitely impacted.
