開啟processing去程式素描本安裝函式庫，去下載video

file-範例-video-movie-loop 然後執行

記得把影片先丟進去，然後打程式

import processing.video.*;

Movie movie;

void setup() {

  size(560, 406);

  movie = new Movie(this, "launch2.mp4");

  movie.loop();

}

void draw(){

  image(movie,0,0);

}

void movieEvent(Movie m){

  m.read();

}

先叫出GettingStartedCapture

import processing.video.*;

Capture cam;

void setup()

{

 size(640,480);

 String[] cameras = Capture.list();

 for(String name : cameras)

 {

   println(name);

 }

}

import processing.video.*;

Capture cam;

void setup(){

  size(640,480);

  cam=new Capture(this, 640,480);

  cam.start();

}

void draw(){

   if(cam.available()){

      cam.read(); 

   }

   image(cam,0,0);

}

原本是紅色，點一下滑鼠會變成一般紅色一半綠色

void setup()

{

  size(640,480);

  background(255,0,0);

}

void draw()

{

  println(frameCount);

}

void mousePressed()

{

  loadPixels();

  for(int i=0;i<640*480/2;i++)

  {

    pixels[i]=color(0,255,0);

  }

  updatePixels();

  saveFrame();

}

import processing.video.*;

Movie movie;

color[]c={#F0F0F0,#FFF160,#FFC501,#FE9600,#03001C};

void setup(){

  size(640,480);

  

  movie = new Movie(this,"my_webcam.mov");

  movie.play();

}

void draw(){

  if(movie.available()){

    movie.read();

    image(movie,0,0);

  }

}

void mousePressed(){

  movie.pause();

  loadPixels();

  for(int i=0;i<640*480;i++){

    float bright - brightness(pixels[i]);

    int now = 4-int(bright/67);

    pixels[i] -c[now];

  }

  updatePixels();

}
