  Question about blinking expressions

  Posted by Pero Marjorie on December 15, 2021 at 2:03 am

  I found a very useful blink expression.

  In this expression, I want to control the blink rate of the start and end points.

  Is there any way to solve this?

  <font style=”vertical-align: inherit;”><font style=”vertical-align: inherit;”>var blinks = 5; // The number of times to blink while fading in. you can change this and it will recompute for you

  var blinkFrames = blinks*2;

  var inFrame = timeToFrames(thisLayer.inPoint);

  var outFrame = timeToFrames(thisLayer.outPoint);

  var currentFrame = timeToFrames(time);

  if (currentFrame < (inFrame + blinkFrames)) {

  var deltaFrame = currentFrame – inFrame;

  if (deltaFrame % 2 == 0) {

  0;

  } else {

  linear(deltaFrame,0,blinkFrames,10,value);

  }

  } else if (currentFrame < (outFrame – blinkFrames)) {

  value;

  } else {

  var deltaFrame = currentFrame – (outFrame – blinkFrames);

  if (deltaFrame % 2 != 0) {

  0;

  } else {

  linear(deltaFrame,0,blinkFrames,value,0);

  }

  }
  </font></font>
