I am trying to make a video with a script(2023\_02\_01\_12\_28\_44/ParaViewScript.py in the folder linked below).  
The video looks alright at the beginning, but from some point, it gets too noisy, as in the photo(full video is 2023\_02\_01\_12\_28\_44/animations/2023\_02\_01\_12\_28\_44.avi ).  
This does not happen 100%, it’s sometimes okay, and can occcur at different timings.  
How can I avoid this?

I put the paraview client information at the bottom. My OS is Ubuntu 22.04.1 LTS.

The script and the data are
