You could really watch as many as you want since you have diamond membership. Study openings with chessbase or some other database

I just got a diamond membership. I'm looking for suggestions on which videos to watch because most of the videos are 15+ minutes long and I don't want to waste my time. I'm currently 1500 USCF and just started to study openings.
