When I save my videos to my camera roll, the quality is quite degraded. Is there a setting I'm missing?
Can you please elaborate? The question is unclear in its current form. What camera, what format, what is the workflow being used?
There is no setting for changing the render quality of your resulting videos in PremiereClip
Instead, you might want to send the project to PremierePro, then edit there.
It'll keep the edit intact in the XML too.
