Maybe like this:

var color1 = effect("Color Control")("Color");
var color2 = effect("Color Control 6")("Color");
var color3 = effect("Color Control 4")("Color")
var colors = [color1,color2,color3];
var idx = Math.floor(random(colors.length));
colors[idx];

or like this if you want each color to hold longer than 1 frame:

var color1 = effect("Color Control")("Color");
var color2 = effect("Color Control 6")("Color");
var color3 = effect("Color Control 4")("Color")
var colors = [color1,color2,color3];
var nFrames = 5;
var f = timeToFrames(time);
seed = Math.floor(f/nFrames);
seedRandom(seed,true);
var idx = Math.floor(random(colors.length));
colors[idx];

Once you apply an expression to source text, you’re stuck with a single style for all the text. Easiest is probably to use two layers and position the second line using sourceRectAtTime() to measure the first line.

[Dan Ebberts]

Ah, sorry, forgot that part. Try this:

m = marker;
easeTime = .25;
n = 0;
if (m.numKeys > 0){
  n = m.nearestKey(time).index;
  if (time < m.key(n).time) n--;
}
temp = n;
c = 0;
while (temp > 0){
  if (m.key(temp).comment == "") break;
  c++;
  temp--;
}
c > 0 ?  ease(time,m.key(n).time,m.key(n).time+easeTime,c-1,c) : 0

Something more like this maybe:

m = marker;
easeTime = .25;
n = 0;
if (m.numKeys > 0){
  n = m.nearestKey(time).index;
  if (time < m.key(n).time) n--;
}
n > 0 ?  ease(time,m.key(n).time,m.key(n).time+easeTime,n-1,n) : 0

[Dan Ebberts]

I’m not exactly sure what you’re after, but this is how I’d calculate how long it’s been since the last marker with no comment:

m = marker;
t = 0;
if (m.numKeys > 0){
  n = m.nearestKey(time).index;
  if (time < m.key(n).time) n--;
  if (n > 0){
    for (i = n; i > 0; i--){
      if (m.key(i).comment == ""){
        t = time - m.key(i).time;
        break;
      }
    }
  }
}
t

Something like this maybe:

function ConvertKeyframesToMarkers(){
	var comp = app.project.activeItem;
	if (! comp || ! (comp instanceof CompItem)){
		alert("No comp active.");
		return;
	}
	var props = comp.selectedProperties;
	var prop;
	var layer;
	var marker;
	var markerVal = new MarkerValue("");
	markerVal.label =1; // red
	for (var i = 0; i < props.length; i++){
		prop= props[i];
		layer = prop.propertyGroup(prop.propertyDepth);
		marker = layer.property("Marker");
		if (! (prop.propertyType == PropertyType.PROPERTY)) continue;
		for (var j = 1; j <= prop.numKeys; j++){
			marker.setValueAtTime(prop.keyTime(j), markerVal);
		}
	}
}
ConvertKeyframesToMarkers();

This should give you the last line:

txt = text.sourceText;
lines = txt.split("\r");
lastLine = lines[lines.length-1];

[Dan Ebberts]

To make it 3D I think you can just change toComp to toWorld in the the curPos and nextPos definitions.

[Dan Ebberts]

Still not quite right. Should be closer:

n = effect("Slider Control")("Slider").value;
if (n >= 1000000){
  Math.floor(n/1000000) + n.toFixed(2).substr(-3) + "M";
}else if (n >= 1000){
  Math.floor(n/1000) + n.toFixed(2).substr(-3) + "k"
}else{
  n.toFixed(2);
}

[Dan Ebberts]

Try this:

numSlider= effect("Slider Control")("Slider").value.toFixed(2);
numSlider.replace(/\B(?=(\d{3})+(?!\d))/g,",");

Edit: Sorry – I misread the question–for some reason I thought you wanted to add commas to large numbers.

Maybe like this?

n = effect("Slider Control")("Slider").value;
if (n >= 1000000){
  Math.floor(n/1000000) + n.toFixed(2).substr(-3) + "M";
}else{
  Math.floor(n/1000) + n.toFixed(2).substr(-3) + "K"
}
