This is another error I could find reported here, it happened with two of my videos, just see the below:
Jump to 43:54 and see as the image turns blocky, like a low band internet connection and then it returns to normal...
Watch from 3:10 until 4:14 and see, it happens a lot of times, it keeps turning to low and high resolution... You can see it in various parts of this video. In both cases, the capture is perfect, the problem is the result from my project exported with HitFilm.
The template I use for all my videos:
Width: 1920 pixels

My HitFilm is the latest version and so my Video Driver.
