Warped/pixelated clips

I'm working off of DaVinci Resolve 15, and when I try to import my clips, they're all warped and pixelated. When I first opened the project, it gave me a notification about my clips and timeline having some sort of mismatch, so I think the warping could be traced to that potentially? I've tried tinkering around in Project settings, but nothing seems to fix it. The clips are playing fine offline, so I know it's something to do with Da Vinci.
Would anyone be able to help?
