Best method of cloning 4k OBS scenes/layout for lower resolution canvas.
I stream/record PC games at 4k 90% of the time. In the few instances I'd like to play a console game that maxes out at 1080, I'll need to have my canvas set to that.
I'm hoping someone has a pain free way to clone my 4k setup, and have all my sources/scenes scaled from 4k to 1080. Thanks in advance!

IMO you ideally would just want to scale the console capture source to4K, rather than changing your canvas and all other sources down to 1080p. Lots less to do every time you switch to that 1080p console
And at that point the only thing you need to do is scale that one source between 4k and 1080p, which takes like 3 clicks in OBS (click on the source in the scene source list -> right click -> transform -> scale to fit)
I haven't looked at the image quality yet to compare it, but if we're talking something like zelda on the switch... I can't imagine upscaling that 1080p image to 4k would look good. That was my concern and reason for the ask. It's an assumption that may be false, so I can at least look into it. But if there is a way to accomplish what I'm after I'd prefer to keep the native resolution of the game.
I'm assuming you're either streaming to YouTube, or recording to edit and then upload to YT
For streaming, you can just up the bitrate of the stream, and use codecs like HEVC or AV1 to greatly improve the quality for viewers (if those codecs are available on your GPU)
For recording, just use CQP rate control and lower the CQP value until the quality looks good enough (and use HEVC or AV1 on your GPU if it supports it)
Realistically upscaling in OBS should look fine with enough bitrate, but if you want you can try to upscale the capture source with this Nvidia SuperResolution filter if you have an Nvidia GPU: https://obsproject.com/forum/resources/obs-rtx-superresolution.1890/
Just note that this upscaling may look great but it'll be more resource intensive. Should be fine if you're not gaming on the system that's handling OBS, and you can just turn off the fliter when you go back to native 4K games

OBS RTX SuperResolution
A plugin to enable nVidia RTX Video Super Resolution features as a source filter.
Allows the use of RTX AI SuperResolution or GPU accelerated Upscaling.
These can be combined with an RTX AI Artifact Reduction pre-pass mode as well to further...
