  Vertical Loop

  Posted by James Simpson on November 3, 2011 at 5:08 pm

  Hi there, NEWBIE EXPRESSION USER ALERT!!!
  Thank you for your patience in advance.
  So I have a poem in vector/ai form and want to loop this so that it scrolls vertically over and over again.
  I’ve searched this forum and found what I think is the answer but I don’t know how to apply the answer!?!

  Dan Ebberts the genius of all expressions suggested this on a previous post:

  spd = 1.0; //scroll speed (pixels per second)

  [width,height]/2 + [0,time*spd]

  All help would be really, really appreciated.

  Thanks, Jim

  spd = 1.0; //scroll speed (pixels per second)

  [width,height]/2 + [0,time*spd]

  If the entire poem fits on the screen, you could add the Offset effect to the text layer, and use an expression like this for the Shift Center To parameter:

  spd = -50.0; //scroll speed (pixels per second)
  value + [0,time*spd]

  If the poem is too long to fit on the screen, it gets a little more complicated.
