  Make a list of words appear one at a time, and control with slider.

  Posted by Sam Nevens on July 27, 2019 at 5:49 pm

  Is there a way to have a list of words appear one at a time, and use a slider to control when they appear? Ideally I would have key frames where 1 = the first word in the list, 2= the second word and so on.

  My end goal is to have a project with a list of names that rapidly goes through them all, and when it gets to the end it slows down. The client wants to be able to add to the names every week, so I’m trying to come up with a way I can just add the names to the list, and not mess with keyframes every time I update the project.

  Any suggestions would be greatly appreciated.

  Try this. Put all the names in a comp. Add a slider effect to the first one. Add this expression to the slider, so it only gets integer values:

  Math.round(value);

  Then add this to the opacity of each layer:

  (thisComp.layer(1)("Effects")("Slider Control")("Slider") == index) ? 100 : 0 ;
