Question / Help Why are there two different "Rescale Output" Options?

[drewlinskii]

I'm just really curious as to why there are two different "Rescale Output" options.

Settings > Output > Rescale Output - https://gyazo.com/4aba675fb5ee5d55e83fe159f4502b12

Settings > Video > Output (Scaled) Resolution - https://gyazo.com/f893347caa6027956e0cffe1da011fe6

I was messing around with both settings, and found that the Rescale Output under 'Output' is what is actually goes out to the stream, and the Output (Scaled) Resolution is the OBS Canvas resolution?

Downscaling in Settings > Video is done on your GPU and allows the use of filters. That video is then sent to Settings > Output where it can be rescaled using the CPU if you choose. You generally don't need to use the CPU rescaling options under Settings > Output unless you need to stream and record at different resolutions.

Thanks for that clarification. So does this mean there's a way to essentially "turn off" the CPU rescaling? The only two ways I could see it "turning off" is to change the 'Output Mode' to Simple or to just uncheck the 'Rescale Output?'

Unchecking "rescale output" is all you need to do.

"Settings > Video > Output (Scaled) Resolution" - better quality Downscaling than any software. (IMHO)

Question: Why does not the Upscaling in non-standard resolution?

example: 1280x1024(5:4) -> 1350x1080(5:4)
1350x1080 changes to 1348x1080 or 1352x1080
this is due to the macro-block 4x4?
1350 is not divisible by 4 to make it an integer 1350/4= 337.5 :(
