Bad export resolution, but looks fine in preview window.
When editing a video, everything looks good in the preview window, but when I export it to my PC, it suddenly becomes all grainy. And when I upload to YouTube, the settings only go up to 480p, even though my Premiere Pro and my OBS settings are both at 1920x1080p. This has happened multiple times now, and I want to find a quick fix since I can't stand seeing my videos like this. All images that might be helpful are down below;
