I was messing with the code that gerge had posted to create a spring between objects:
// AE expression by George Polevoy
// attaches an object to a “Controller” object with a “spring”
// You need another “Controller” which will drive animation of this one
// parameters
conserveMotion = 0.95; // valid range: 0.5 to 0.995
springResistance = 10; // positive values
prerollTime = 2; // value in seconds. greater values give more precise result
//
fps = 1.0 / this_comp.frame_duration;
if ( prerollTime > time ) prerollTime = time;
dt = this_comp.frame_duration;
frame = time * fps;
integrationTime = time – prerollTime;
s = [0,0];
p = this_comp.layer(“Controller”).position.value_at_time( integrationTime );
i = frame – prerollTime * fps;
for (; i < frame; i++, integrationTime += dt ) { c = this_comp.layer("Controller").position.value_at_time( integrationTime ); d = c - p; s = s + d * springResistance; s = s * conserveMotion; p = p + s * dt; } p; When I do it I keep getting the warning "expression must be of dimension 2, not 1. Anyone know what Im doing wrong? Josh

You can copy a path from ilustrator or from the mask shape in ae and paste it into the position channel. so if you have a circle mask or a circle in ill, and you click on position in a layer and paste, the layer will move in a circle. I think thats what you are trying to do.Josh

Steve,
Thanks for the response, exactly what I needed. You rule.Josh

shoot, steve beat me to it.

Dude-
use the pen tool to draw the lines exactly where you want tthe reveal to happen, and then apply effect/render/stroke. In the effects panel change paint style to “reveal original image” and then keyframe the start poition.you might need to adjust the stroke width, and you can try it with stoke sequentially turned on and off to see the difference.
good luck.

One other question Ted. Did you shoot the ink and transparencies on just basic dv or was it film?
