  Constant Motion Expression

  Posted by Ryan Perera on December 3, 2010 at 5:49 pm

  I’m not sure how to do this but I have a feeling it has an easy solution…

  Basically I have two keyframes that are moving a solid at a certain speed along the X axis. I want to use that same speed along the rest of the solids duration.

  I swear I knew how to do this awhile ago but I haven’t touched after effects in awhile and forgot.

  Just add this to the Position property:

  loopOut(“continue”)

  Sometimes you just want something to move constantly without keyframing it. Use throw.

  // Throw (move at a constant speed without keyframes)
  veloc = -10; //horizontal velocity (pixels per second)
  x = position[0] + (time – inPoint) *veloc;
  y = position[1];
  [x,y]
