From these two videos i realize how to create a successful debut music video:

• Good costumes will make everything look a lot more professional
• A variety of editing and different camera shots/movements can make the video much more interesting
• If a mistake is made we must shoot again to make the video better.
• Always shoot so that the performing actor is lip syncing whilst looking into the camera
• Choose appropriate mise-en-scene
• Dance routines in unison look real good
