Hi Rob.

Replacce var zoom = compEditing.layer(1).text.sourceText.value with var zoom = compEditing.layer(1).text.sourceText.value.text.

Your code returns a variable that is of type TextDocument, not string. That variable also contains font, fontSize, fontFamily, text and other data.

Hi Clement. I think you need one of the following expressions, based on whether the second value of y position is greater or smaller than the first. The linear() function needs the 2nd parameter to be smaller than the 3rd.

So if the position of your second keyframe is lower than the first, use this

dropMenu = effect("Dropdown Menu Control")("Menu");
myListe = [195.7, 258.2, -320.7];
myPlace = myListe[dropMenu - 1];
key1 = key(1).value[1];
key2 = key(2).value[1];
yVal = linear(value[1], key1, key2, key1, key2 + myPlace);
[value[0], yVal];

Otherwise, use this

dropMenu = effect("Dropdown Menu Control")("Menu");
myListe = [195.7, 258.2, -320.7];
myPlace = myListe[dropMenu - 1];
key1 = key(1).value[1];
key2 = key(2).value[1];
yVal = linear(value[1], key2, key1, key2 + myPlace, key1);
[value[0], yVal];

You need to modify these a little to fit your project.

Yes. When rendering, it calculates that expression only once, at the start of the composition. It should only be used for expressions that do not change for the entire duration of the composition.

Autoleading is equal to 1.2 of the size of the font. However, if the autoleading is selected, myStyle.leading returns the value that the leading had before autoleading. So if your font is 100 px and leading 80 and you decide to set autoleading, the paragraph looks as if the leading would be 120. But myStyle.leading still returns 80. So that is why that line is there.

Hi Tomas. sourceRectAtTime reads only the text size if used with false value for include extents. Like this sourceRectAtTime(time, false).height;

If all you want is to know how many lines there are, you can use this function for that.

//L=layer, T=time
function getNumRows(L, T) {
    var H = L.sourceRectAtTime(L.sourceTime(T), false).height;
    var myStyle = L.text.sourceText.style;
    myFontSize = myStyle.fontSize;
    myLeading = myStyle.autoLeading ? myFontSize * 1.2 : myStyle.leading;
    return Math.ceil((H - myFontSize*0.5) / myLeading);
}
getNumRows(thisLayer,0);

You need some more information, as the time for each marker. IDK of such a script but it would not be that hard to do one. Here is one that puts a marker from your file at each second

var myFile = File.openDialog("Please select markers file");
putMarkers(myFile);
function putMarkers(myFile) {
    var markers = [];
    if (myFile.open("r")) {
        var fileString = myFile.read();
        markers = fileString.split("\n");
        myFile.close();
    } else {
        alert(myFile.error);
    }
    for (var i = 0; i < markers.length; i++) {
        addMarker(app.project.activeItem.selectedLayers[0], markers[i], i + 1);
    }
    function addMarker(myLayer, comment, time) {
        var myMarker = new MarkerValue(comment);
        myLayer("Marker").setValueAtTime(time, myMarker);
    }
}

When you set the duration of the composition it is a composition object. You can’t set the startTime of a composition object. For startTime, you need a layer object. That means that first you have to put your composition inside another composition. When you have done that, you have your composition used as an AVLayer inside the second composition. Only on this one can you set the startTime.

The numbers don’t seem to react to the .toUpperCase() function. If I use .toUpperCase() on “andrei popa” I get “ANDREI POPA” but if I use it on a number, nothing happes. The numbers only seem to react to the “All Caps” button from the character panel. I don’t know how to apply that button effect to only one part of the text.

[Andrei Popa]

I can test this if you can give me an example of a font that has upper case numbers (never heard of such a thing actually). Whithout testing, this could work, written in the text source.

 text.sourceText.replace(/^[0-9]+$/, function(v) { return v.toUpperCase(); });

Are your texts always gonna be on same line?

If ever the words are too long and they have to descend to the next line, things get a lor more complicated. I imagine the simplest case would be 2 words, left justified texts. Second word should have this attached to the position. They should also be consecutive in the timeline, meaning the first word should be the layer above the second word.

posterizeTime(0);
L = thisComp.layer(index - 1);
R = L.sourceRectAtTime(0, false);
W = R.width;
diff = 20;
L.position + [W + diff, 0];
