So, i have an animation of a car moving, and i’m trying to use mask on it, exactly the same video, but i only exported the alpha channel.  
I’m trying to play them simultaneously, so they overlap, but they seem to be playing at different timings, so it looks like this:

And my code looks like this:

```auto
import processing.video.*;
PImage img;
Movie video, mask;
void setup() {
  size(600, 840);
  img = loadImage("comtexto.png");
  img.resize(width, height); 
  video = new Movie(this, "1.mp4");
  mask = new Movie(this, "2.mp4"); 
  mask.loop(); 
  video.loop(); 
}
void draw() {
  background(img);
  video.mask(mask);
  image(video, 0, 0);
}
void movieEvent(Movie m) {
  m.read();
}

```

Why aren’t they overlapping? They are exactly the same size and length video.

i think there is no control what frame ( of what second of a video ) you can show.  
( as actually processing does not know video / sound …  
it just talks to JAVA and that talks to operating system )  
so your computer will try to start first one video and then the other one…  
like independently.

no idea if ( at end of setup) a final

```auto
myMovie1.jump(0.01);
myMovie2.jump(0.01);

```

would improve ( not existing ) sync
