If you are speedrunning the entire campaign, be wary of music copyright. The only level you need to worry about is in Block World, the second world. The music in the Village level is copyright claimed, and will demonetize your video and may put up ads, if you haven't put them down before. So, you can mute the music in the Village level, or leave it in if you don't care about money from the video or forced ads for viewers. This will NOT put copyright strikes on you if you upload it.
