I have reached out to Reddit about this topic but found no help there. Long story short I have tried every obs setting in history and still can not record a video that is even remotely bearable.

You can see all the information about this in this link. https://www.reddit.com/r/obs/commen..._recording_quality/?utm_source=reddit-android

I believe that there is some external cause to my constant terrible quality videos. Even when I increase my settings an that changes is the increased file sizes, the quality is still horrid. If anyone has some ideas it would be greatly appreciated.
 
Your problem is that you're using CBR for recording.
Switch to CRF or CQP with a rate control value in the 14 range.

Thanks for the Swift response, I will try this tomorrow as it is late here however can I just ask how this change will effect my recording?
 
CRF and CQP are quality-target bitrate selections, allowing the encoder to decide for itself what the bitrate should be.
Using CBR to record hard-caps the picture quality at the bitrate you've selected, and ends up wasting bitrate on lower motion content that doesn't actually need the bitrate you've specified.

I have tried this but I'm still getting bad looking video recordings. The colours look horrible even though my settings are on 709 nv12 full. Also doing that increased my file size tremendously though the quality varied little. Any ideas?

Actually it's more likely BECAUSE you're using 709 full.
Try 709 partial or even 601 partial.

Okay so I have just changed it to 601 full nv12 and the colour looks much better. The video itself still looks quite low quality though.
My current settings are:
base res: 1920x1080
output res: 1280x720
downscale: Lanczos
fps 60
encoder x264
mp4
rate control: CRF - 14
cpu usage preset ultrafast.

What can i change here to make the quality improve?
 
Maybe you can explain or show what you are talking about, when you say "quite low quality".
Sure, downscaling to 720p will result in less sharpness (especially text will look bad, when you compare it to your native resolution), but other than that, x264 CRF 14 should look very clean.
 
It's the full color range that is causing the problem, not the depth.
And saving directly to mp4 is strongly NOT recommended.
 
MKV for multichannel audio. FLV if you don't need that.

After that, use the command in the File menu to remux the file to another container.

If anything happens during mp4 recording, the resulting file will almost certainly be unrecoverable. Not true for other containers.

Okay I just tried these settings however I noticed a large quality drop when recording to FLV, is there no way to stop this quality drop from occuring?
 
Only changing the container format doesn't change the quality. It's as if you have to transport a stew from the kitchen to the place where the meal takes place. It's irrelevant if you fill the stew in a soup plate, or if you eat it out of the pot, or if use a different kind of dish. It's exactly the same stew. The same is with the container formats and the video that is contained in them. It's bit for bit exactly the same video, regardless of the container format.

If you encounter a large quality drop when recording to flv, you changed something else in addition to the container format. Or you recorded something different than before, for example something that has different CPU usage, so you perhaps now get frame drops where before there were none.
