Hello. I'm very new to processing and I'm trying to use moviemaker to add a frame captured from a video feed (when spacebar is pressed), to the end of an existing video file, before saving the newly combined video again. Are there any examples floating around of a smart way to do something like this? Thanks in advance.

Here's what i have so far:

import processing.video.*;
Capture myCapture;
MovieMaker mm;  // Declare MovieMaker object
void setup()  
{
 size(768, 432);
 myCapture = new Capture(this, width, height, 30);
 initialiseMovieMaker();
}

void captureEvent(Capture myCapture) {
 myCapture.read();
}

void draw() {
 image(myCapture, 0, 0);
}

void keyPressed() {
 if (key == ' ') {
   mm.addFrame();  // Add window's pixels to movie
   mm.finish();  // Finish the movie if space bar is pressed!
   initialiseMovieMaker();
 }
}

void initialiseMovieMaker(){
 mm = new MovieMaker(this, width, height, ""+year()+month()+day()+hour()+minute()+second()+"_snapshots.mov",30, MovieMaker.H263, MovieMaker.HIGH);
 // need to somehow add existing frames from previous movie to mm here.
}
