What is a good bitrate for recording 1080p 60FPS

[RPX_Editor]

Hi, so this is my first post on this forum and want my videos to look as best as they can, while keeping a file size some-what reasonable. I didn't want to go to YouTube because recommendations they are all over the place. Plus, it varies on your rig & editing, etc,. Anyway, I have been recording on YouTube for a lot of years *ReaperpwnX* on YouTube and was wondering if my videos are as good as they can get, or If I can change anything to get better quality. ps. I am aware of YouTube's Codec system and upload in 1440p so I can get the better processing. Anyway!

Specs:
CPU: I7-7700k
GPU: 3060Ti
RAM: 16GB
Storage: 2x 1TB HD's / 1x 500GB SSD.

My current OBS settings are 1080p 60FPS CBR 8000 Kbps, Max Quality, High.

I've seen some discussions about changing to CQP or VBR but, I am unfamiliar with them & don't mess with any of them. I attached a log-file too in-case any extra information is needed.
Any advice would be great on what to do, or just leave it. Thanks! :D

Very knowledgeable comments (ie, not from me ;^) in this thread that address your question. https://obsproject.com/forum/threads/best-settings.140188/#post-514693
in general, you must real-time Stream using CBR (required by receiving platform), but for recording only (or if you have resources for separate recording vs streaming encoding), better to record using CQP or VBR as you've read.

As for file sizes, Koala recently posted (iirc) about CPQ quality with a value change of 3 or 4 = doubling in file size..???
from the above thread

CQP is a quality-based encoding target that uses as much or as little bitrate as is needed to maintain a given image quality level.​

22 is the normal 'good' point, 16 for 'visually lossless', and 12 is generally the lowest you'll want to go even if you plan to edit the video later (to cut down on re-encoding artifacts). The lower the number, the closer to 'lossless' video it gets. But below 16 the filesizes get ridiculously large very fast.​

In the above thread is reference to Psychovisual Tuning - not that turning it off is something to do ONLY after you've done everything else and still having encoding issues. For me, my system (not gaming) is not running into issues with Lookahead and Psychovisual Tuning turned on.

What I've learned over the past couple months is that constqp is the way to go. This is how you get actual VBR! In games I've watched it go between 5Mbps and 50Mbps!

Since you have an Nvidia card you can use HEVC. I use rc=constqp qp=30 with I444 color for games and it looks great. For screen recording video you want closer to qp=20. I444 uses more CPU than NV12 according to folks on this forum so stick with that if I444 is too slow

These are my settings

Interesting settings, thank you for showing your set-up with me. I might give it a try!
