For folks like me who have not yet learned the utterly massive amount of details and information required to make good choices around the project settings and the rendering settings in VMSP 17 (and apparently also in Pro). I found what I think is a great resource that explains a lot about these subjects in terms I could understand. I don't know enough to comment on the accuracy of the explanations but it sure filled a huge gap in my understanding. Check out Derek Moran's Movie Studio Zen tutorial at the weblink below.
Hope this helps
