Magewell Owners, some help needed (questions)

EDIT** Disregard the main post, I figured it out. I still have a few questions. Can somebody post some suggested settings?. I've been using Dxtory and MagicYUV which would record roughly 50-80MB/s and I was happy with the quality at 1080p.

Can somebody suggested some settings to use that would give roughly the same quality or better if possible?. I don't want to use x264 or NVEC codec as the quality isn't really that good to me.

I record at 60FPS at 1080 or 720 to SSD's so speed isn't really a concern.

Thanks a lot guys

What settings are you exactly looking for? You said that your recordings are coming out fine so what seems to be the issue?

Some possible recording settings. I've never used OBS studio before as I've been using Dxtory and MagicYUV. I plan on recording with a Magewell card and am looking for some format/bitrate/container etc. settings if anybody has any.

I just tried using Lossless and NVENC which was okay but still not as good as using the Magic codec same with using Matroska and Huffy

Quality at CRF 15 would be nearly identical to the source. I've been personally using it and I am unable to perceive any quality loss

There are 2 reasons (AFAIK) why colours would be different from your source

1.Chroma Subsampling

2."Encode in full range" setting not enabled in OBS

If you are uploading to youtube then the colour will get washed out regardless of what video you upload

So color range should be a partial then?. Is CRF the same as CQP? (I'm using Studio). If I had the space/power would just recording at Lossless NVENC be better than your x264 settings in terms of quality?

Thanks for the help..

NVENC is a lower quality encoding method that still goes to x264. It requires significantly more bitrate than the software encoder to not look like complete hot trash.

Follow the local recording guide posted above, and do enable full-range to avoid color skew. It defaults to partial color to cut down on encoding load and bitrate primarily for livestreaming as I understand it, but if you're recording locally that should be a non-issue.

Yeah I agree I'm not a big fan of NVENC either.. I think the quality and colors look like $hit lol but it was an option.. I plan on recording on a separate PC with SSD's so space and power won't be a concern. Like I asked before do you think recording in lossless at 7gigs/min would be better quality than x264 or no?.

Also CPU preset should be slower for better quality correct?

Quality for local recording is better done with bitrate, not preset. Put the preset on Superfast and increase quality with bitrate, qp, or crf (depending on which you're using). Changing the preset too slow will just give you duplicated frames, which looks horrible.

Can you recommend some settings? codec/format. I tried recording at 100k/60fps and the video looked decent but that was with NVENC.

Alright well I'll have to keep playing with settings I guess. The video that keeps being created has artifacting or doesn't look that good

Post an OBS log file from a 5 minute or longer attempt while recording high action gameplay while using the settings in the guide.

P.s. I have neither of those but I do use a Datapath capture card.

Ok I'll see what I can do later (video encoding right now lol). I've never recorded with a cap card so I'm an extreme noob. I found this link https://obsproject.com/forum/resources/almost-lossless-local-recoding-using-obs-mp.200/
which was kind of helpful at least for recording settings and the video file was actually created correctly the colors seemed washed out with RGB but 4:4:4 looked decent with a 50MB/s bitrate

That guide is using OBS Studio, not OBS Classic, FYI. And if I were to do it, I'd switch it to SuperFast instead of UltraFast, as some x264 quality features are switched off in UltraFast that can't be made up for with more bitrate.

Yeah that's what I've been using is OBS Studio this entire time. I'm still doing some testing on what quality I like and what Premiere Pro can handle..I want to get as close to lossless quality as possible like I could with MagicYUV even at 4:2:0.

Here are some of the settings I have been testing, any recommendations on changes?
