  Sliding letters

  Posted by Emmanuel Gobert on November 17, 2013 at 2:52 pm

  Hi eveyone,
  please have a look at the very beginning of this video : https://vimeo.com/51056859 especially how the words “le supplement” appear

  I’d like to reproduce that animation. I’ve tried this expression by Dan Ebberts, which is nice but the problem here is that the letters are bouncing, not only “sliding”….

  freq = 2;
decay = 5;
delay = .15;
dur = .12;

  myDelay = (textIndex-1)*delay;
  t = time - (inPoint + myDelay);
  startVal = 100;
  endVal = 0;

  if(t < dur){
linear(t,0,dur,startVal,endVal);
}else{
amp = (endVal - startVal)/dur;
w = freq*Math.PI*2;
endVal + amp*(Math.sin(t*w)/Math.exp(decay*t)/w);
}

  So my question is : how can I achieve that kind of animation ?

  If you look further in the video, you will see very nice shape layers animation.
  Do you know some great tutorials to achieve such animations ?

  Thanks a lot !

  Are you talking about the words at the bottom? I think I’d use a Position Animator with an Expression Selector with an expression like this:

  delay = .02;
  slideDur = .3;
  myStart = inPoint + textIndex*delay;
  easeOut(time,myStart,myStart+slideDur,100,0)

  Set the y position to somewhat below the original position and create a mask so that the letters aren’t visible until the expression moves them up. Something like that.
