  wiggle on a certain time.

  Posted by Jun Ishiwata on February 27, 2012 at 10:04 am

  Hello,

  I’ve been looking for wiggle expressions all day yet can’t find the explanation to my problem. I’ve inserted a video that i made in premiere pro and i would like to ad a wiggle on for instance frame 10 to frame 50 but then stop the wiggle. The expression Wiggle(5,50) for instance just wiggles my whole movie. is there a way to change the expression or code so it wiggles on a given frame to a given frame?

  Thank you .

  Probably the easiest way is to just attach the amplitude parameter to a slider which you would keyframe from 0 to 50 and back to 0:

  amp = effect(“Slider Control”)(“Slider”);
  wiggle(5,amp)

  That also lets you ease into the wiggle because if you just turn it on abruptly, the layer will jump.

  Have a nice day

  timeToStart = 2; [second]
timeToStop = 4; [second]

  if ((time > timeToStart) && (time < timeToStop)){
wiggle(3,25);
}else{
value;
}

  Dan!

  It’s been a few years since this post, but this seriously made my day. Thank you so much, and I only wish I knew this years ago. Such a nice, simple expression, but so handy, and can potentially be extrapolated to control so many other expressions!

  Thank you sir! Seriously, I’ve been telling everyone I know trying to find someone who will get as psyched about it as I am.
