I thought that your previewing screen didn’t determine how your video will look till the very end when you actually type in what rendering quality you want so mine is always left on preview (auto). I so far have already tried rendering out in project settings, preview, good, and best with my preview screen on auto (if that makes a difference) and none looked closest to how it actually looked like on the preview screen.
Knowing this information, I went ahead anyway and tried adjusting my preview screen to best or even good and rendering it accordingly but it still didn’t turn out the way I wanted it to.
