record in 5760x2880 without jerks.

Hello, I am trying to record VR game videos to transform them into VR180 videos that can be watched on YOUTUBE VR but even if on YOUTUBE the rendering is clean, on YOUTUBE VR it is not clean.

A youtuber but said that I had to record in 5760x2880 because if I do it in 3840x2160 and I encode in 5760x2880 it will never be clear.

I try to record with OBS but the CPU is running at 100% and I have jerks.
Could someone tell me the right settings to keep good visual quality in VR and be able to record in 5760x2880 and stay fluid?

My pc setup: I7 10700K / RTX 3080 TI FE / 32 Go RAM

It's right. You will lose image clarity. Another thing, what is the resolution of your monitor?

2560x1440

I would like to know one thing. Is it better to record with high bitrate and encode with lower bitrate or record with lower bitrate and encode with high bitrate?

Unfortunately, your video will never be as crisp as you expect. You have a 2K monitor and you just stretch the pixels to 5K or 4K, it doesn't matter. What you've been told only makes sense if you have a 4K monitor. In any case, if you want to shoot in 5K, then you should use NVENC HEVC, because. maximum resolution for NVENC H.264 4096 × 4096. NVENC h.265 8192 × 8192

Basically you can shoot in native 2K and stretch to 5K or 4K in a video editor. It will be the same, only you need to specify the bitrate for the final resolution. Plus, a scaling filter is available in obs, which makes the picture clearer when zooming. I know Adobe Premiere has the same thing, it's called "Maximum Render Quality".

Example. If you are recording in 2K and specifying a bitrate of 100 Mbps for 2K. But in a video editor, you will stretch the resolution up to 4K. In this case, you specify the bitrate when recording as for 4K, that is, 2 times more. 200 Mbps. When rendering, you also specify 200 Mbps. In this case, everything will be in order, except for the loss of clarity, but not quality. I hope you understand.

Try the following settings.

You should choose the bitrate yourself, but the more the better. Depends on HDD space. If we are talking about 4K, then be prepared to work with tens of gigabytes of data. CQP will not suit you, because. you must know the target bitrate in order to specify it in the video editor.

Oh thank you for all these details.
The problem is that I make videos for youtube and a 20 minute 4K video at 80Mbits/s is almost 20GB. I don't know how much youtube allows in video volume.

The maximum file size you can upload is 256 GB or 12 hours, whichever is less.

OK, thanks.
What I find strange is that on youtube the videos are very beautiful but in the vr headset (quest 2) the details are average.

That's why I have to record in 5760x2880 to get closer to the resolution of the headphones.

In fact I have to increase the bit rate a lot when I encode.

I was doing the opposite.
I record in 3840x2160 80Mbits/s and I encode in 5760x2880 60 Mbits/s
