  Changing time from seconds to frames in expression

  Posted by Obed Ampong on April 6, 2020 at 1:29 pm

  Hello,

  Please, the expression below has the time duration in seconds however I would like to change it to the number of frames.
  Thank you in advance.

  Regards,

  Obed

  function easeInOutCubic(t, tMin, tMax, value1, value2){
b = value1;
c = value2-b;
d = tMax-tMin;
t = tMin < tMax ? thisLayer.linear(t,tMin,tMax,0,d) : thisLayer.linear(t,tMin,tMax,d,0);

  t /= d/2;
  if (t <1) return c/2*Math.pow(t,3) + b;
  t -= 2;
  return c/2*(Math.pow(t,3) + 2) + b;
  }

  duration = 1;

  start=[-2000,540,-2000];
  destination = [960,540,0];
  exit = [2000,540,-3000];

  middle = (inPoint+outPoint)/2;

  v = time < middle ? easeInOutCubic(time,inPoint,inPoint+duration,start,destination) : easeInOutCubic(time,outPoint-duration,outPoint,destination,exit);

  Change the declaration of duration variable. That first number is the number of frames.

  duration = 30 * thisComp.frameDuration;

  There are also expressions to convert a value in seconds to frames and vice versa:

  timeToFrames(seconds);
framesToTime(frames);
