Animation of shapes

Here's a nice Political Truth Meter the networks can use whenever a politician is speaking on camera. It was done in AviUtl just for fun:

Some fun with sin and cos avisynth animations...

Here's the function for the bouncing character:

function Bounce(clip vid, clip overlay, clip mask, int x, int y, int angle, int amplitude)
{
   radians = float(angle) / (360.0 / PI / 2.0)
   yoff = sin(radians) * float(amplitude)
   yoff < 0 \
    ? Overlay(vid, overlay, x+angle, y + int(yoff), mask) \
    : Overlay(vid, overlay, x+angle, y - int(yoff), mask)
}

# call with:

Animate(0, 360, "Bounce",\
   last, dog, mask, -130, 380, 0, 100,\
   last, dog, mask, -130, 380, 640, 100)

great! excellent! magnificent! superb! splendid! awesome! - Thx jagabo - You've made my day!

Here's the code to move the overlay in a circle:

function Circle(clip vid, clip overlay, clip mask, int x, int y, int angle, int radius)
{
   radians = float(angle) / (360.0 / PI / 2.0)
   xoff = sin(radians) * float(radius)
   yoff = cos(radians) * float(radius)
   Overlay(vid, overlay, x+int(xoff), y+int(yoff), mask)
}
