  Frame by frame effect (plugin or expression?)

  Posted by Giorgio Terzo on February 24, 2019 at 11:55 pm

  Dear all,

  I am trying to reproduce this effect (https://www.facebook.com/clive.hicksjenkins/videos/10156370564303198/) in an animation trying to manipulate the position and skipping some frame with the following expression (thanks to Dan Ebberts!):

  // Skipping frame
n = 2; // skip every nth frame

  frameToSkip = 0; // 0,1,2 ...n-1
currFrame = Math.round(time/thisComp.frameDuration);
currFrame += Math.floor((currFrame - frameToSkip)/(n-1)) + 1;
framesToTime(currFrame);

  //change the update of the position
rate = 5;
//add some randomenss
prob = 50;
if(random(0, 100) < prob) {
rate = rate + random(0.05);
}
t = framesToTime(Math.floor(timeToFrames()/rate)*rate);
valueAtTime(t);

  The problem is that I have to apply the second expression in each moving elements and sometimes the animation is “not really controllable”.
  Does exist a better a method (or maybe a plugin) in order to achieve this kind of effects? A sort of master effect that can be applied for all animation?

  Thanks!
  Giuliano

  Oh wow. Ya, what Dave said. No need to “Tex Avery” something like that certainly.

  Bur if you’re looking for something more along stop motion lines, you might look at this though. Goes back aways but still works effectively.
