  How can I ‘toggle hold keyframe’ or start and stop and expression?

  Posted by Kevin Tang on March 3, 2020 at 3:53 am

  Hi, I am trying to make a wiggle expression start and end at a certain point. I have tried using a slider. but it doesn’t work with toggle hold keyframe. Further, I don’t want a gradual interpolation but a definite start and stop. I can’t split the layer because of how wiggle position work (it doesn’t begin at the same location).

  Hi,

  I’ve just published a tutorial covering this exact thing:

  In the video, I use regular keyframes, but it just a case of switching these to hold keyframes to get the result you’re after.
