 # Scene Transitions
 
 A transition tells the viewer how two scenes relate. A crossfade says "this continues." A push slide says "next point." A flash cut says "wake up." A blur crossfade says "drift with me." Choose transitions that match what the content is doing emotionally, not just technically.
