  This adapted example works for me: :-\"

  boolean isPaused;
  
  void setup() {
    if (mv == null) {
      ( mv = new Movie(this, "MVI_2686.MOV") ).loop();
      while (mv.width == 0)  delay(50);
    }
  
    size(mv.width, mv.height, JAVA2D);
  
    noSmooth();
    noLoop();
    frameRate(30);
    imageMode(CORNER);
  
    pg = createGraphics(width, height, JAVA2D);
    pg.beginDraw();
    pg.noSmooth();
    pg.imageMode(CORNER);

  }
  
  void draw() {
    pg.background(mv);
    pg.endDraw();
    background(pg);
  }
  
  void mousePressed() {
    if (isPaused ^= true)  mv.pause();
    else                   mv.play();
  }
  
  void movieEvent(Movie m) {
    m.read();
    redraw();
  }

  Yep great your example works fine. I can see there are a few differences to mine notably the JAVA2D setting, the delay(50); and redraw(); Will using JAVA2D effect what platforms the sketch can run on? Thanks for the format code link too!

  JAVA2D is the default renderer. Using size() w/o specifying a 3rd parameter implies JAVA2D!

  I suggest to read it attentively and to train on the previous message, which you can edit... :-D

  So it turns out I just had to supply the renderer type in the createGraphic method. Now I can use P2D or P3D if I choose. Which I do, as I'm hoping to use createGraphics as a buffer and do multiple passes, before outputting and thought this should speed things up?

      import processing.video.*;
      
      PGraphics pg;
      PImage img;
      Movie movie;
      
      
      void setup() 
      {
        
        size(640, 480, P3D);
         
        pg = createGraphics(width, height, P3D);
        
        ///img = loadImage("iStock_000015044044Small.jpg");
        movie = new Movie(this, "MVI_2686.MOV");
        movie.loop();
      }
      
      void movieEvent(Movie m) {
        m.read();
      }
      
      void draw() 
      {
        pg.beginDraw();
        //pg.image(img, 0, 0, width, height);
        pg.image(movie, 0, 0, width, height);
        pg.endDraw();
        image(pg, 0, 0); 
      }
