hey guys,

i just wrote a little music visualization program and now i want to export it as a video.

i used the MovieMaker with addFrame and finish. so far so good. it generates a .mov file if i start it, but it it only becomes 129kb big and when i finish the program this file jumps back to 2kb.

something seems to be written wrong but i can't see where my fault is. i also dont know how much keyframes i should use.
maybe you guys can help me out. here's the code.


import processing.video.*;

import ddf.minim.*;


MovieMaker mm;
Minim minim;
AudioPlayer player;
 
void setup () {
  // Sketch einrichten
  size (1920, 1080);
  noStroke ();
  smooth ();
  mm = new MovieMaker(this, width, height, "test.mov",
                     30, MovieMaker.H264, MovieMaker.BEST,5);
 
 
  minim = new Minim (this);
  player = minim.loadFile ("Cragga_-_Please_Mr_Postman__Dubstep_Refix_.mp3");
  //player = minim.loadFile ("SATURATE!RECORDS - heRobust - Albumin Ep (STRTEP002) - 10 Shawty Swing My Way (Busted).mp3");
  //player = minim.loadFile ("02-mount_kimbie-would_know.mp3");
  //player = minim.loadFile ("Kaczinski - Fuck this Melody2.mp3");
  player.play ();
 
}
 
 

void draw() {
 
  fill (0,50);
  rectMode (CORNER);
  rect (0, 0, width, height);
 
  float dimension = player.mix.level () * 600;
  rotate(PI/dimension * 10);
 
  println (dimension);
 

  for(int y = 960; y <= height; y = y + y^5){
    fill(dimension/5,3,100);
    triangle(width/2, 0, dimension, dimension, 600, y);
   
    fill(y/4,y^33,dimension);
    triangle(width/2, 600, 0, y, 600, y/66);
   
    fill(y,dimension,dimension);
    triangle(dimension * 2, dimension, 0, y, 600, y);
   
    fill(y + 10,dimension,dimension);
    triangle(dimension + 100, dimension + 18, dimension, y, 350, y);
   
    fill(y^99,dimension,y^233);
    triangle(width/2, 22, 150, y, 450, y);
   
    fill(33,33,y^233);
    triangle(dimension + 300, dimension + 22, 100, y, 500, dimension);
   
    fill(222,dimension,y^233);
    triangle(dimension, dimension, 33, y, 600, y);
   
    fill(dimension * 2,dimension/4,y^233);
    triangle(dimension * 3, dimension + 20, 0, y, dimension, y);
   
    mm.addFrame();
  }
    import processing.video.*;

      


}
   void keyPressed() {

  if (key == 's' ) {
    mm.finish();  // Finish the movie if space bar is pressed!
  }
}
