  Time To Next Keyframe Expression

  Posted by Mar Perez on June 6, 2023 at 1:19 pm

  Hey, just wrote an expression to find the (fractional) time to next keyframe. Hope someone finds this useful.

   

  var textlayer = thisComp.layer("Commentary").text.sourceText;
  var nrstkey = textlayer.nearestKey(time);
  var ind = 0;

  if(nrstkey.time<=time){
  ind = nrstkey.index+1;
  }else{
  ind = nrstkey.index;
  }

  var result = “”;

  if(ind-1==0){
  var ttnextkey = textlayer.key(ind).time-time;
  var rounded = Math.round(ttnextkey*100)/100;
  result = rounded+”s”;
  }else if(ind>textlayer.numKeys){
  result = “fin”
  }else{
  var ttnextkey = textlayer.key(ind).time-time;
  var tbetwnkeys = textlayer.key(ind).time-textlayer.key(ind-1).time;
  result = “|”.repeat(Math.ceil(ttnextkey/tbetwnkeys*10));
  }
  result;
