how do i change project aspect ratio?

[anthonyz46849428]

im trying to make YT shorts so I need a 3:4 ratio (1080x1920) instead of 4:3. Everywhere I look says to go to edit > project settings > general and change "frame size"'s horizontal and vertical values, but it doesnt let me edit those at all.

Might have read this for Premiere Pro (older versions) but there is no way you can change them in Elements.

ok, is there a different way to change aspect ratios then?

This tutorial shows you how to change project settings differently

Changing Project Settings in Premiere Elements - YouTube

but most likely not going to work as vertical video is not supported in Elements.
