3840x1600 black bars no good or?

[ridergg]

Hello, I need help.
I want to make Sim Racing videos for YouTube-16:9 my is 21:9
My setup is
Alienware 38 AW3821DW
AMD 5950x
RTX 4080
I it possible to adjust 21:9 to 16:9 in obs I was trying for 2 days but no luck.
1440p is not the option because then my CPU bottlenecks GPU.
So should I just sell this monitor and buy 4K
16:9 to make things easier.
Sorry for my bad English and thanks in advance for any help and suggestions.

Possible solutions:
1) if possible, run game at 16:9 and use centered output for the display device (thus you play 16:9, capture 16:9; of course, part of the screen is not used);
2) apply filter Scaling/Aspect Ratio and set Undistort center of image when scaling from ultrawide checkbox in the properties of this filter.

Can I just rescale output to 3840x2160 to get 16:9 without black bars for YouTube? It looks I can, what do I lose, some part of image?

That rescale output is located in Video section. So base and canvas is set to 3840x1600 and in Video section rescale output is 3840x2160

Re-scale is a second "resizing" and was designed for streaming (in case you have poor connection today and planning to upload full quality record of the stream event later).

OBS puts to output what you see in the Preview (or in the Program window) of OBS. You just crop/resize (or place out of view) your video sources in OBS preview and what you see - will be saved as media file. If you see in OBS preview 16:9 - it will be 16:9 at output without any rescaling. Just set Canvas and Base resolution to the same 16:9 value (for example 1920x1080) then you can place even 8k image into the preview and adjust its size/position/crop as you wish (via the right-click menu -> Transform).

I cannot recommend upscaling. Let's users do it if they wish.
