Question / Help Recording in a different resolution to my monitor.

hi guys, I've started recording gameplay for my brother who then intends to edit this into videos and dmso on.

I have an issue though that is my monitor is a 3440x1440 resolution which results in huge files that obviously then need converting to a 1080p image.

Is there a way in OBS to record in this resolution?

Downscale to 1080p?

Settings > Video > Canvas: 3440x1440
Scaled > 1920x1080

You can try Rescale on the Output Tap too. Dont know where is the Difference between this two Downscale Options

Settings > Output > Recording > Rescale Output.

If you use the second Option, i think you have to set Canvas and Scaled in the first Option to 3440x1440

But dont know that exactly.

I'm using the newer obs version and it doesn't have the second option there. Changing the base canvas is is not an option either, it appears fixed on my native resolution. Should I switch to the classic OBS? Are they possible on the older version?

how did you realize 3440x1440? nvidia surround? I dont know if the canvas is important to recordings, so perhaps you can irgnore that. normaly you can set the canvas exactly to the same resolution your display are. and with nvidia surround, you has only one resolution. made of serveral displays.

you have to put the output mode to advanced to see the second option to rescale.

settings > output > output mode

if i remember correctly, your displays are 21:9. if you downscale to 1080p, you will have black bars in your video.

You can click in both the "Base (Canvas) Resolution" and "Output (Scaled) Resolution" fields and enter values manually.

Hi guys, thanks for the feedback. I've tried writing my own scaled output but it seems to just compress the 21:9 image width ways rather than just record the 16:9 centre portion of what's going on.

You'd need to set your Canvas resolution to 1920x1080 and then crop the source, I think. To be honest I don't know if that would work or not.

You are using a 21:9 device. With YouTube, you need 16:9 ratio to fit in the player. If its 4:3, you get pillar bars.
More here:

Set the canvas to be the same size as your display resoluton set in your graphics card. If that is 3440x1440 set it to that.

Set the Output scale resolution to be a 16:9 ratio, like 1920x1080 so that it conforms to YouTube ratios. See what happens after your record and playback in Windows Media Player. What it looks like will depend on the scaling algorithm OBS uses to downsize images. Try all three downscale filters, Each is going to do its own thing. There is no wrong or right way to downscale. Its the result that is left for interpretation that matters.

Its either going to work or not work for you. If it doesn't, then don't use 3440x1440. Set your GPU resolution display resolution to a custom 16:9 that is close to it that will let you play on your monitors but have the minimal of black bars while you play (assuming there is not stretching). Then target to 1920x1080 to keep the aspect ratio and reduce fuzziness.

Hope that makes sense.
