Random video

Hi everyone, a newbie question here. I´m trying to select video files that will play in a random sequence. Every time I replay the sketch I see a new video, but does anyone know how to get them to play in sequence without refreshing the sketch? I´m probably missing something obvious here, grateful for any help!

import processing.video.*;

String[]vid = {"action1.mp4", "action2.mp4", "action3.mp4", "action4.mp4", "action5.mp4", "action6.mp4"};

Movie movie;

void setup() {
  size(480, 270);
  background (255);
  frameRate(30);
  movie = new Movie(this, vid[int(random(1, 6))]);
  movie.loop();
}

void movieEvent(Movie m) {
  m.read();
}

void draw() {
  image(movie, 0, 0 );
}
