I want to create youtube shorts in portrait format but can't change aspect in OBS

Hi, I can capture video from webcam and screen in OBS but when I go to settings>video I can't change aspect ratio. This page on yololiv seems to suggest these video options may depend on hardware, eg video card. That might explain why I can't make my canvas portrait mode.
I have done due diligence and searched for previous posts on this topic and rexodus jan 2022 was advised to go to settings > General > Studio Mode > Enable vertical/portrait layout.
I have no studio mode under general in my settings in OBS.
If I can't find a portrait layout then I will have to try aother programme, movari or kapwing, or screenccastomatic. Why are there so many? I have tried streamyard but it doesn't support portrait mode either, as far as I can tell. Would appreciate advise on other progs too.
log file, not that I think it's relevant: https://obsproject.com/logs/rLRGBhb61KuAXMiz
thanks
