Hi Guys,

I'm very new in processing world. So sorry if my question is a bit silly.

I'm trying to write a code that actually sectionned an instant movie (from the camera of your computer for instance) in several images and put it in a grid, and for this I found this code:

/**

* simple overview of a video file.

*

* KEYS

* s : save png

*/

import processing.video.*;

Movie movie;

// horizontal and vertical grid count

// take care of the aspect ratio ... here 4:3

int tileCountX = 12;

int tileCountY = 16;

float tileWidth, tileHeight;

int imageCount = tileCountX*tileCountY;

int currentImage = 0;

int gridX = 0;

int gridY = 0;

void setup() {

size(1024, 1024);

smooth();

background(0);

// select path and load video

String path = selectInput("select a video file ...");

movie = new Movie(this, path);

tileWidth = width / (float)tileCountX;

tileHeight = height / (float)tileCountY;

}

void draw() {

float posX = tileWidth*gridX;

float posY = tileHeight*gridY;

// calculate the current time in movieclip

float moviePos = map(currentImage, 0,imageCount, 0,movie.duration());

movie.jump(moviePos);

movie.read();

image(movie, posX, posY, tileWidth, tileHeight);

// new grid position

gridX++;

if (gridX >= tileCountX) {

gridX = 0;

gridY++;

}

currentImage++;

if (currentImage >= imageCount) noLoop();

}

void keyReleased() {

if (key == 's' || key == 'S') saveFrame(timestamp()+"_##.png");

}

// timestamp

String timestamp() {

Calendar now = Calendar.getInstance();

return String.format("%1$ty%1$tm%1$td_%1$tH%1$tM%1$tS", now);

}

Than I found that code that actually take a picture from the camera of your computer every 5 minutes.

/**

* timelapse camera. after each intervalTime a picture is saved to the sketch folder

*

*/

import processing.video.*;

Capture myCam;

// intervalTime in sec. here 5 min

int intervalTime = 5*60;

int secondsSinceStart = 0;

String startTime = getTimestamp();

int counter = 0;

boolean doSave = true;

void setup() {

size(640, 480);

println(Capture.list());

//String s = "Logitech QuickCam Messenger-WDM";

//myCam = new Capture(this, s, width, height, 30);

myCam = new Capture(this, width, height, 30);

noStroke();

}

void draw() {

if(myCam.available()) {

myCam.read();

image(myCam, 0, 0);

secondsSinceStart = millis() / 1000;

int interval = secondsSinceStart % intervalTime;

if (interval == 0 && doSave == true) {

String saveFileName = startTime+"-"+nf(counter,5);

saveFrame(saveFileName+".png");

doSave = false;

counter++;

}

else if (interval != 0) {

doSave = true;

}

// visualize the time to the next shot

fill(random(0,255),random(0,255),random(0,255));

rect(map(interval, 0,intervalTime, 0,width),0, 5,5);

}

}

String getTimestamp() {

Calendar now = Calendar.getInstance();

return String.format("%1$ty%1$tm%1$td_%1$tH%1$tM%1$tS", now);

}

Basically, I want to mix those two codes. I want to tell the computer "take a picture from your camera every minute and put it a grid".

I'm tried to re-work those codes together but impossible to get something at the end. I think that I actually have issues with the timeframe of my code.

Can Anybody help me, or give me a piece of advice about how I should process?

Thanks a lot in advance.
