Quicktime files are green on timeline

I am running the free version of Davinci Resolve 16, and I recently did a pick up shoot. When I added the new files they show up green on the timeline, any idea what the problem is?

Have the same type of files worked before? What format are these files? Which Resolve version?

This kind of errors usually seem to stem from gpu problems, but could also be from decoding errors. Have you recently updated gpu drivers?

Did you shoot the pick-ups in 10 bit maybe?
