The equilibrium for the hunger games is that when everything went normal then changed instantly for instance when everything went as normal but then they take her little sister then the older sister retaliates then she takes her place to go into a tournament for survival. At 45 seconds into the trailer that's where the equilibrium was spotted when everything went normal than they do a death raffle then her little sister wins but her older sister in agony then she volunteers for this into an adventure also another moment in the film were the moments have changed were that when she finds her friend dead and she avenges her but when she found her dead she was in a deep sad scene. The disequilibrium is when she gets chosen to do the tournament and also the new equilibrium is not shown because  if you want to see it you have to watch the film. The action codes were when she picks up an arrow and she points at someone then that's a close up at the weapon the audience will infer somebody is about to die.
