My run need be streamed? or can be a Youtube video following the rules?

(sorry, i'm new on speedrun community)

Hey, i need know, i need put timer on the video or i can publish only the gameplay without the timer?

Hello, I wanted to know if in the 7-star category, you need to get the 7 stars in Bob-omb Battlefield, or I can pick up some at Whomp's Fortress because I would waste time collecting the 100 coins

Thank you for your attention.
