When i import a video onto Premiere  Pro, the video is defective (photo). 

On my computer the video is reproducing correctly. 

Using App Mediainfo I recovered these informations about the video

What is your graphics card?

 

And have you tried going to the Project Settings dialog and setting Mercury Acceleration to software only?

 

I do believe that is a graphics issue ...

    This was precisely the problem. I managed to solve. 

    Thank you very much for your help

    My Premiere barely works on a full SSD system with a 3900x and 32 gigs of ram unless I use hardware acceleration. When I had an issue with green artifacts I went to preferences, general, and unchecked "display color management." That fixed the issue for me for video, although I still had an issue with jpegs.

    It could also be a graphics card driver issue. Go to the website for your graphics card and make sure you have the latest driver.

    Thank You Neil I have just chacked and I have the latest drivers. 

    Also VLC is able to reproduce the video correctly. The problem is only on Premiere Pro.

    I think the problem is probably the variable frame rate.  Use handbrake to convert to a constant frame rate

    https://handbrake.fr

    If you have any questions about the settings, post back or do some searching here for the best workflow

    I have used Handbrake to convert the video to 30 FPS constant but the problem persist.
