I would like to know how can I export a motion of text into a video format. My code looks like this:

PFont font;
float x1 = 0;
float x2 = 100;
void setup() {
 size(100,100);
 font = loadFont("Tahoma-16.vlw");
 textFont(font);
 fill(0);
}
void draw() {
 background(204);
 text("Poor", x1,50);
 text("Rich",x2,100);
 x1 +=1.0;
 if (x1 > 100) { x1 = -150; }
 x2 -=0.8;
 if (x2 < -150) { x2 = 100; }
}
