  How to provide a specific frame to an expression

  Posted by Mark Antonio on July 29, 2009 at 5:03 pm

  hello guys,

  i want to add an expression to a specific time. for this i use the following expression:

  if( time > 94 && time < 98 ) { wiggle( 3,15 ) }else{ value; }

  the problem is, i don’t know how to exactly provide a specific time like 00:01:34:17.

  could you pros please tell me?

  regards, mark

  You could do the conversion from timecode to seconds like this:

  timeString = “00:01:34:17”;
  splitTime = timeString.split(“:”);
  t1 = (parseInt(splitTime[0],10)*60 + parseInt(splitTime[1],10))*60 +
  parseInt(splitTime[2],10) + framesToTime(parseInt(splitTime[3],10));

  There’s probably a simpler way, but I can’t think of one off hand.
