I am new at this so am trying to catch up.

Hello. Read around here enough and you'll find that every person has a preference for their quality and whether or not they see any degredation in the video. You'll honestly have to play with it and figure out what best suits you. The quality enhacement settings and the deep analysis are great features that can really help improve the quality under compression. But in the end, it's up to your eyes to decide how much compression and whether or not to use the deep analysis and quality enhancements.
