Forgive me, I am using blender for the very first time while typing this. I learned from YouTube and created and rendered a short 96 frame animation using the ProRender for Blender 3.1.25 and the final rendered file looks pretty bad. The quality does not match the progress shown in blender's render viewer. Like I said, I really don't know what I'm doing but hopefully someone knows where I went wrong.
The only setting I customized in the output menu is the render quality (set to Full)
