I had noticed one of my video's looked a ton better than the rest, I went back and looked at the file size and output settings. Setting it to MP4 and best quality made a noticeable difference. The output size was pretty big, over 3gb for an 8 minute video, but compared to ones that were done with a bit-rate limit set, or the youtube default in davinci, the quality difference even after being uploaded and encoded by youtube was noticeable. I now know what I need to make my default, and just deal with the large file size and upload time.
