FuckpassVR, VRHush and LethalHardcoreVR Original bitrates are 90mbps, files are not too big (around 25GB) and quality is great.
SLR Original sometimes go over 190mbps with file size up to 100GB.
Bitrate comparison test
Every one here assumes more bitrate = more better
Many even believe more K = more better

90Mbps is a little bit high, but at least FuckpassVR and VRHush also offer 45Mbps as alternative on their website.
CzechVR uses 60 or 80Mpbs depending on the scene. For most other studios 60/62Mbps is the maximum they use for 7/8K scenes, so I guess something between 55Mbps and 75Mpbs would be a good compromise between size and quality.
For SLR's current 6k vids: 60Mbps
For SLR's future 8k/9k vids: 90Mbps
doublevr Good to hear that SLR is on it to improve this! This will probably even be more visible on some of the upcoming headsets like the crystal so it's also some future proofing right there.
Personally I wouldn't download the originals anymore if there was a higher bit rate version available. However, I must say, I'm still glad that the originala are there. It's just a nice escape hatch for when you feel the encoding is not optimal or when you want to make sure.
g2kbuffetboy id like to see 40 mbps for the lower quality/streaming 8k versions instead of the current 22 or 30. 40 is high enough for the image quality to look acceptable at that resolution and low enough to not be wasting too much bandwidth and to work without buffering delays for people with 50 mbps internet connections.

edit: sorry, got the wrong links
doublevr The Max Q file is 4x larger but bitrate and fps are the same? Why is that?
- Edited
Yeah despite being 4X larger bitrates are the same, MediaInfo shows this for MAX_Q file "Stream size: 259 MiB (30%)", and this for 30M file "Stream size: 259 MiB (99%), so i would assume, as they have same stream size, that files are the same, only MAX_Q has some junk data in it or something.
MediaInfo shows that they have same encoding settings, also for MAX_Q it shows "IsTruncated: Yes", that only happens when file is not expected size, or is corrupted, etc.
SchnuppiLilac hes trying to play us for fools again. the videos are totally identical but the max q one has exactly 600mb of random data appended to the end of it to make it bigger.

Hey guys, we went into full research mode today, trying to figure out the difference between original file and max streaming one that we provide for download, the difference is there but miniscule.
The example we used, granted, did not have a full frame of moving things, so lets say it was average content.
We will continue to test on "harder" examples like some harem scene, where the girls are all around the camera.
Will keep you updated with our findings.
Also we have a memory leak with playing original files, we will fix this, so you can watch them too.
Can I ask who are we actually addressing here, the people watching downloaded files, or people watching porn by streaming?
Sandi_SLR both hopefully. I'd like to see downloaded files at their maximum visual fidelity, and for streaming to be greatly improved.
g2kbuffetboy We're going to have a lot of complaints and cancelations I guess.
There are users who don't even have the possibility to get a connection fast enough for 30Mbps

Sandi_SLR Netflix has a tool for quantifying image quality.
https://github.com/Netflix/vmaf
Which should close the debate about bitrate, which is no measure of quality. That's ridiculous.
You don't decide how good a cook is by how tall they are.
There's 1000 variables that influence this.
Most of all, complexity of the image and complexity level of the codec.
Both of these determine the macroblocks and temporal vectors.
L6 encoding will yield a smaller bitrate of the same video encoded at L4 at equal quality.

Me, personally, 98% downloads right now. But I certainly wouldn't mind better quality for streaming since quality is pretty much all that counts for me. Best quality in streaming might convince me to use more streaming in the future tbh.

Setting up VMAF is not the easiest thing in the world. And you need to make complete decompressed YUV versions of the videos to use correctly.
But, you can use it on this web page with your mp4 files!
Comparing full scenes will take forever this way. I suggest using Shutter Encoder (Free), and use the Cut Without Re-encoding feature to take some excerpts from the scenes and compare them.
VMAF is a well known tool made by Netflix to objectively measure quality difference between encodes of the same video.
- Cut Without Re-encoding is the very first function in the list of the Shutter Encoder app.
IMPORTANT!
Then in the editor I suggest using a starting time and end by typing it in.
- Lower left, In point
- Lower right, Out point
The app will automatically pick the correct keyframe for not re-encoding!
EXTRA IMPORTANT!
Also in the editor, in the upper left, click Image adjustment. It will by default always be set to enabled. Even though all settings are at default, I always make sure to disable it, just in case!
Then in the upper right of the editor, click Apply, followed by Start Function.

You replied here yesterday that bitrate means nothing, later you deleted the post.
That is just not true.
Higher resolution = More Information, how else are you gonna transmit that information than increasing bitrate.
6K - 5800x2900=16,820,000 pixels
8K - 8000x4000=32,000,000 pixels
So you are telling us that doubling amount of pixels, doesn't also require increasing bitrate.
If that is true Netflix would use same bitrate for all resolutions, but they don't, they use about 6mbps for 1080p, and around 15mbps for 2160p.
Also netflix is not known for their picture quality, almost all other streaming services have better picture quality than them.
Also i don't need some tool to tell me difference between encodes when i can see it with naked eye. For 6K difference between 30mbps and high bitrate file is almost negligible (except in some rare cases like outdor shot with moving foliage or low light scenes), but for 8K that difference is much bigger and i can clearly see it.

Here is comparison between 8K 30mbps and Original 8K 90mbps. Scene is Aubree Valentine "Consumated Passion" from VRHush.
I selected two random frames, and cut everything beside Aubree face.
Here are they as a gif so they are easier to compare.
And here individually.
