hi
i recently start to learn processing and i want to play "Brightness Thresholding" ,which is in the example-video, with a video i've already recorded at the same time. i don't know how to combine these two codes. can anyone help me?
code:
Brightness Thresholding

import processing.video.*;

color black = color(0);
color white = color(255);
int numPixels;
Capture video;

void setup() {
  size(640, 480); // Change size to 320 x 240 if too slow at 640 x 480
  strokeWeight(5);
  // Uses the default video input, see the reference if this causes an error
  video = new Capture(this, width, height, 24);
  numPixels = video.width * video.height;
  noCursor();
  smooth();
}

void draw() {
  if (video.available()) {
    video.read();
    video.loadPixels();
    int threshold = 127; // Set the threshold value
    float pixelBrightness; // Declare variable to store a pixel's color
    // Turn each pixel in the video frame black or white depending on its brightness
    loadPixels();
    for (int i = 0; i < numPixels; i++) {
      pixelBrightness = brightness(video.pixels[i]);
      if (pixelBrightness > threshold) { // If the pixel is brighter than the
        pixels[i] = white; // threshold value, make it white
      }
      else { // Otherwise,
        pixels[i] = black; // make it black
      }
    }
    updatePixels();
    // Test a location to see where it is contained. Fetch the pixel at the test
    // location (the cursor), and compute its brightness
    int testValue = get(mouseX, mouseY);
    float testBrightness = brightness(testValue);
    if (testBrightness > threshold) { // If the test location is brighter than
      fill(black); // the threshold set the fill to black
    }
    else { // Otherwise,
      fill(white); // set the fill to white
    }
    ellipse(mouseX, mouseY, 20, 20);
  }
}

code:
video

import processing.video.*;
AppletLayers layers;
Movie theMov;

void setup() {
  size(1080, 1080);
   layers = new AppletLayers(this);
  theMov = new Movie(this, "ScreenFlow.mov");

  /* only use 1 of the following options */
  theMov.play();  //plays the movie once
  theMov.loop();  //plays the movie over and over
}

void draw() {
  image(theMov, theMov.width/4, theMov.height/4);
}

void movieEvent(Movie m) {
  m.read();
}
