Definitely pretty noticeable. I'm going to hold off on more speculation until a mac user has chimed in, but here is one general thought for you to help speed up your own troubleshooting process. Take one of these clips that are noticeably bad and just work with that instead of your whole project.
Maybe start from scratch with a small clip and see if you can't identify some earlier step that solves your problem, such as avoiding color depth format changes. If you can't keep it in YV12 (4:2:0), at least convert it to something that isn't dropping data, such as YV24 (4:4:4) like your ProRes444 codec you mentioned, or RGB 24 bit (888). I am not an expert on color coding either but maybe it could explain this banding effect?? (I haven't experimented enough with changing the formats to be sure). If you just think about it from a pure bit standpoint, basically what your current workflow is doing is going from 4:2:0 to 4:4:4 to convert back down to 4:2:2 then back up to 4:4:4 and then back down to 4:2:0. That said, this still isn't a satisfactory explanation because your mp4 that looks good is also 4:2:0 and went through the same process.
If the problem lies in your editing file, you can hopefully re-do it and replace without affecting your timeline.
