What do you want your expression to do exactly? Because this seems bizarre. Is this applied to your tracking property? Because it increases it to 2 until it arrives to 2 seconds, then it is 0, then it grows during the last 1.55 seconds of your layer.

This should do it

var myComp=app.project.activeItem;
var myMarker = new MarkerValue("anything");
var myLayer = myComp.selectedLayers[0]
myLayer.property("Marker").setValueAtTime(myLayer.inPoint+2, myMarker);

Update. On my system, this did not work if there were “enter” characters before the highlited word. Every “enter” would offset the highlight by 1. Seems like after effects uses “\r” character for new lines. So this is the final form of the expressions.
For start:
redWord = thisComp.layer("textB")("Text")("Source Text");
newLines = thisLayer("Text")("Source Text").split("\r").length -1;
if ( thisLayer("Text")("Source Text").indexOf(redWord) > -1){
thisLayer("Text")("Source Text").indexOf(redWord)-newLines;
}else{
0
}

And for end:
redWord = thisComp.layer("textB")("Text")("Source Text");
newLines = thisLayer("Text")("Source Text").split("\r").length -1;
if ( thisLayer("Text")("Source Text").indexOf(redWord) > -1){
thisLayer("Text")("Source Text").indexOf(redWord)+redWord.length-newLines
}else{
0
}

redWord = thisComp.layer("textB")("Text")("Source Text");
if ( thisLayer("Text")("Source Text").indexOf(redWord) > -1){
thisLayer("Text")("Source Text").indexOf(redWord)
}else{
0
}

and
redWord = thisComp.layer("textB")("Text")("Source Text");
if ( thisLayer("Text")("Source Text").indexOf(redWord) > -1){
thisLayer("Text")("Source Text").indexOf(redWord)+redWord.length
}else{
0
}


But still does not work well if you have enters in your text. Was trying for a solution because split(“\n”) did not seem to work. Will post here if i manage to find one.

Apply a color animator to your textA with the desired color for the word. Go to “Animator>Advanced” and change “Units” to “Index” and “Based on” to “Characters”

Then, on range selector add this expressions.

This to start:
thisLayer("Text")("Source Text").indexOf(thisComp.layer("textB")("Text")("Source Text"))

And this to End:

redWord = thisComp.layer("textB")("Text")("Source Text");
thisLayer("Text")("Source Text").indexOf(redWord)+redWord.length

This should work. Select the layer you want to use the script on and then run it

var myMarker = new MarkerValue("Insert Comment Here");//leave blank for empty
var frameDuration = app.project.activeItem.frameDuration;
var myFile = File.openDialog("Please select your marker file");
var framesArray = extractDataFromFile(myFile);
var timeArray = (framesArray!=null) ? framesToTime(framesArray) : [];//framesArray must be an array with the numbers from your file
var myLayer = app.project.activeItem.selectedLayers[0];

for (var i=0; i < timeArray.length; i++){
myLayer.property("Marker").setValueAtTime(timeArray[i], myMarker);
}

function framesToTime(framesArray){
var timeArray =[];
for (var i=0; i < framesArray.length; i++){
timeArray.push(framesArray[i]*frameDuration);
}
return timeArray;
}

function extractDataFromFile(myFile){
if (!myFile) return;
markerData = [];
if (myFile.open("r")){
while(!myFile.eof){
var frameNumber = parseFloat(myFile.readln());
markerData.push(frameNumber);
}
return markerData;
}else alert("Could not open your file");
}

You should save all those frame numbers in an array.
then, to put markers on the layer use this
var myMarker = new MarkerValue("Insert Comment Here");//leave blank for empty
var frameDuration = app.project.activeItem.frameDuration;
var timeArray = framesToTime(framesArray);//framesArray must be an array with the numbers from your file

for (var i=0; i < timeArray.length; i++){
myLayer.property("Marker").setValueAtTime(timeArray[i], myMarker);
}

function framesToTime(framesArray){
var timeArray =[];
for (var i=0; i < framesArray.length; i++){
timeArray.push(framesArray[i]*frameDuration);
}
return timeArray;
}

Magic, again. Thank you very much.

I don’t think you can. But you have some sort of workaround. Make a null, put it in the middle of your layer, parent your layer to it and apply the transformations you need to the null.

Fixed it finally. Turns out i failed to test it without the files… Or something. Today i got the same error.
