VIDEO - best codec for minimising processing during playback?

  Just some tips for playback improvements:

  • Prefer JAVA2D renderer for size().
  • Activate noLoop() in setup() and use redraw() in movieEvent() after read().
  • Prefer background() or set() in order to display the Movie.

  import processing.video.Movie;
  Movie mv;
  
  void setup() {
    if (mv == null)  (mv = new Movie(this, "cat.mov")).loop();
    while (mv.width == 0)  delay(10);
  
    size(mv.width, mv.height, JAVA2D);
    noLoop();
    frameRate(40);
    background(#FF00FF);
  }
  
  void draw() {
    background(mv);
  }
  
  void movieEvent(Movie m) {
    m.read();
    redraw = true;
  }

  Cheers - theres a lot going on in the program so can't use JAVA2D or background but the noLoop() technique worked a treat!! Nice one

  Also I converted my video files to QT animations (uncompressed) and it helps alot though the file size is ridiculous!

  ... so can't use JAVA2D...

  In this case, both background() & set() are slower for displaying the Movie/PImage picture.
  That is, for both P2D & P3D renderers, we should use image() instead.

  For our 60fps-application we have tested several codecs and recorded automatically the real fps:

  frm = frames per s
  KyF = keyframes
  
  fps = average fps over 600 frames
  min = minimal framerate within the 600 frames
