  • Final Rendered Video is Sped Up Compared to Animation Played in Processing

    15 janvier 2016, par Nightlife

    Recently I made an Audio Visualizer in Processing. From there I wanted to render the animation created in Processing into a mp4 file. I am on a windows computer, and am using ffmpeg to convert my TIF files produced in Processing into mp4.

    When I do this I am able to render the images into an mp4 file, but when I playback this file the animation is sped up compared to the animation when I play it on Processing. Because of this the animation does not sync with the audio when I combine the mp4 file and audio on a video editing program.

    When I set my frame rate to 25 and have the limit on the number of frames to be 250 and render it into a mp4 file it is 10 seconds long like it should be, but it contains more than 10 seconds of the animation when compared to the animation played directly in Processing.

    I have no idea why this is so any help will be much appreciated.

    My Processing code :

    import ddf.minim.*;
    
import ddf.minim.analysis.*;
    

    
Minim minim;
    
AudioPlayer player;
    
PImage img;

void setup() {
    
  size(728, 546);
    

    
  minim = new Minim(this);
    

    
  // this loads mysong.wav from the data folder as a stream with a internal buffer of size 1024
    
  player = minim.loadFile("new_years_good.mp3");
    
  fft = new FFT(player.bufferSize(), player.sampleRate());
    
  player.play();
    
  img= loadImage("cat-in-shades-.jpg");
    
  frameRate(25);

  float a = 0;
    

    
  float angle = (2*PI) / 200;
    

    

    
  fft.forward(player.mix);
    

    

    
  for(int i=0; i < player.bufferSize() - 1; i++) {
    

    
   //player.mix.get(i) is a value between [-1,1]
    

    
    float x = 250 + cos(a) * (20 * player.mix.get(i) + 100);
    
    float x2 = 540 + cos(a) * (20 * player.mix.get(i) + 100);    
    

    
    float y = 230 + sin(a) * (20 * player.mix.get(i) + 100);

    float y2Final = 240 + sin(a+angle) * (20 * player.mix.get(i+1) + 100);    
    

    

    
    line(x,y,xFinal,yFinal);
    
    line(x2,y2,x2Final,y2Final);
    
    a += angle;  
    

    

    

    
  }
    
  noStroke();  
    
  fill(255, 0, 0, 128);
    
  for(int i = 0; i < 250; i++)
    
  {
    
    float b = fft.getBand(i);
    
    float yAxis = random(-b, b) + 480;
    
    float xAxis = i*3;
    
    ellipse(xAxis, yAxis, b, b);
    
  }
    
  saveFrame("frame-####.tif");
    
  if(frameCount>250)

      noLoop();
    
      stop();

void stop() {
    
  player.close();
    
  minim.stop();
    

    
  super.stop();
    
}
