render music visualisation movie

hi

i'm making music visualisation with processing
and i wanted to render a movie from
my different sketches.
i load in the mp3 / or live via mic
and set the framerate to 30
at the end of draw i'm setting

saveFrame("flashigNeu2-####.png");

for making a png-sequence

but it doesnt give me all 30 frames per second
there are only like 10

the performance is then very slow,
could it be that the cpu is too slow
but it want to do it in time
so it only gives me that many fps
which it can render ?

is there another way to do something like this ?

NApplet and childApplets

Hi

perhaps somebody can help me with this.

I'm making an applet out of many other applets
using the NApplet library.
Until now everything is ok. BUT.

When i'm making a "subApplet" using the NApplet
and this applet has a class for making stuff in his mainApplet
the programm doesnt recognize the class and tells me
things are missing

for example:

i have something like a standart flock applet in it
but it doesnt work in the big NApplet because he cant find the birds-class

i tried it both in eclipse and processing

anyone got an idea ?

thanks in advance

hi

i wrote several music visualizer via processing

now i want to merge them together into one sketch

and assign each sketch a butten/key etc.

do i have to rewrite them as classes?

i hope somebody can help me

for example 3 of my sketches:

Sketch1

int actRandomSeed = 0;

int count = 10;

import ddf.minim.*;

Minim minim;

AudioInput in;

void setup() {

  size(400,400);

  background(0);

  smooth();

  minim=new Minim(this);

  minim.debugOn();

  in=minim.getLineIn(Minim.STEREO,512);

  frameRate(60);

}

void draw() {

  background(0);

  noStroke();

  //float faderX = (float)mouseX/width;

  float angle = radians(360/float(count));

  for (int q=0; q<in.bufferSize();q=q+1) {

   for (int i=0; i<count; i++) {

   // positions

   float x = width/2 + cos(angle*i)*q;

   float y = height/2 + sin(angle*i)*q;

   // float x = lerp(randomX,circleX, faderX);

   //float y = lerp(randomY,circleY, faderX);

   // fill(0,130,164);

   fill(in.right.get(i)*100000,in.right.get(i)*10000,255-in.right.get(i)*100000,50 );

   ellipse(x,y,in.left.get(q)*100,in.right.get(q)*100);

   }

  }

}

void keyPressed() {

  if(key==ENTER) {

  }

}

Export Video + Sound

Hi

I did a few Music Visualizations via Processing

and i want to export them from Processing to .mov.

I already used the MovieMaker function, but it doesnt record the sound.

is there a possibility to record the sound too ?

How can i make the exported Movie in Realtime,

as it played in Processing.

It always looks much faster

mm = new MovieMaker(this, width, height, "drawing.mov", 10, MovieMaker.JPEG, MovieMaker.HIGH);

Is 10 Realtime? Standart is 30 but its always too fast,

my frameRate is 60

Does anyone know how the MovieMaker calculates its fps ?

hope i get help

thanks
