My video is in a horrible quality when I import it

[Roman123]

I have MacBook Pro 2019, but every time i import a video in Premiere Pro, its in bad quality (usually part of video is good anf part of the video is like on screenshot). On the screenshots there are my video opened in QuickTime Playerr, and itts fine, and on the other screenshot ots the same video imported in Premiere Pro. What shoud i do and how do i fix it?
