I came to this thread hoping to learn something because I’m also struggling with render quality on youtube, so unfortunately I can’t really offer much help. If it’s any consolation I think your video looks great. You almost have to be looking for flaws when comparing it to Jessie’s videos in order to see any lack of quality. Would you mind telling me what codec/dxtory settings you’re using? I’ve been using Lagarith 1080p/60fps and the same render settings you have, with a much lower quality outcome.
I mainly ask this because, it seems that you’re using the same render settings as the majority of people who make game play videos. With my experimenting I’m beginning to think that what separates the good and bad videos in quality MUST be during the recording process.
