When I want to export a draft version in 720p of a 4k video, on the 720p I have a lot of elements that change places and stay in their position on the 4k version.
So my preview is bad, I can't find a solution so that Vegas manages to put everything at the same resolution so that no matter the resolution, certain parts of my assembly do not change place
Exemple :
720p
4k
this is my project and render settings :
