Blurring on export

Hello,

New here so be gentle :slight_smile:

Could some look at this snip of my export. I’m having trouble exporting the video without the tearing/blurring you see in it. I’ve exported it once a few weeks ago and it came out fine. Then I don’t know what I’ve changed but whatever I do I can’t get it right. please help.

Core I7
Nvidia M4000
