  Move layer at fixed speed, than stop

  Posted by Joseph Wentzel on January 5, 2021 at 7:32 pm

  Hey all,

  I have a text layer moving up the screen at a fixed speed via expression (moving at 3 whole pixel values to avoid jitter and stuff); kind of like movie credits. I want to have a second text layer move up with the first (at the same speed), but stop before going off the screen.

  I can’t parent it, because I want it to stop part way up.

   

  The first text layer has the following position expression applied to it:
  [value[0], value[1] – time * 29.97 * 3];

   

  1080p 29.97fps Comp

  Any help is appreciated. Thanks

  Hi Joseph, this will do the trick:

  max=500; //y value where you want your text to stop
  y=value[1] - time * 29.97 * 3;
  y<=max && (y=max);
  [value[0], y]
