How to time remap layer using scripting?

Hey!

This is how I'd go about doing it--

(function () {
    app.beginUndoGroup("Time Remap Layer");
    var comp = app.project.activeItem;
    var layer = comp.layer(1);
     
    layer.timeRemapEnabled = true;
    var timeRemapProp = layer.property("ADBE Time Remapping");
    var times = [0, 2, 4, 6];
    var values = [0, 2, 4, 6];
    timeRemapProp.setValuesAtTimes(times, values);
    app.endUndoGroup();
})();

The key parts are `var times = []; var values = [];`. This is where you'd list where you want Time Remap keys to go, and the values you want them to have.

The values I have there aren't going to do much-- it'll add a key at 0 with time 0, a key at 2 with time 2, 4 with 4, 6 with 6.

For your purposes, it depends on how much you want to speed up / slow down things. As you seem to be doing this by eye, the values are really up to you.

Something like this would slow down the first 2 seconds of animation (stretch 0-2 to 0-2.5), speed up the middle (squish 2-4 to 2.5-3.5), then slow down the last two (stretch 4-6 to 3.5-6).

    var times = [0, 2.5, 3.5, 6];
    var values = [0, 2, 4, 6];
