  up/down text scroller in after effects

  Posted by Sean Story on May 7, 2008 at 8:30 pm

  I am somewhat new to the after effects, and I would like to build an animated text scroller using expressions.

  essentially a side bar, with title and beneath coming up from bottom news/statistics in a reasonably smooth fashion(looping).

  any help or pointers would be muchly appreciated.

  thanks for your time

  Precomp your text and put an Offset effect on it.

  Then set an expression for “Shift Center to”:

  t = time * 30;
  x = value[0];
  y = value[1] – t;

  [x, y]

  That will cause your text layer to scroll up and the Offset effect will cause it to loop. To add blank space in the scroll, just add space below the text and make sure your comp is big enough to not cut the text off. I think you’ll get it once you see what it’s doing.
