hi folks,
I'm a newb to processing, so i have watched and read some tutorials and i think it's quite an easy language.
but now i've got a big problem and couldn't find any help.

i want to use mov videos in my project, that i've created with after effects.
they have a transparent background. i exported them with rgb+alpha channel and wanted to add them into the processing environment.

but in there they have a black background, i couldn't get rid off.
is there any possibility to load the transparancy in or is there some kind of colour-mask-filter?

please help me!
cheers

here's the code i've made so far.

Code:

import processing.video.*;

Movie blob;
PImage keys;

void setup() {
  size(1000, 500, P2D);
  background(0);
  blob = new Movie(this, "blob02.mov");
  blob.loop();
  keys = loadImage("keys01.jpg");
  image(keys, 0, 0);

}

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

void draw() 
{
 if (mousePressed == true) {
 image(blob, mouseX - blob.width/2, mouseY - blob.height/2); }
 else
 image(keys,0,0);
}
