I am not sure whether this works with a range selector, but if you animate the typing with an expression or keyframes on the source text, you could have an expression on the time remapping of your keys that checks the last character of the source text and chooses the frame accordingly. var myText = thisComp.layer("my text layer").text.sourceText; var myKey = "a"; var result = framesToTime(0);  // by default I show frame 0 if(myText[myText.length-1]== myKey){ // if the text ends with myKey, I show frame 1      result = framesToTime(1); } result To animate the source text with expressions, you can use my Scroll Text Terminal iExpression: Scroll Text Terminal Expression | mamoworld ...

If you want to write robust scripts, I would not rely on the assumption that the Array object has no additional properties. There are various scripts on aescripts, for example, that do extensions to the general Object prototype as Xavier explained.

What is the difference between starting and stopping vs. starting, stopping and resuming again? It is just starting and stopping it several times. You can link the wiggle amplitude to a slider and keyframe this slider to 0 wherever the wiggle should not wiggle. You can do the same with iExpressions, as shown in this tutorial. Getting started with iExpressions Part 1 - Wiggles | mamoworld One convenient and generic way of doing it is using Expression Timeline. PS: If you want to stop the wiggle abruptly and want to continue the motion path exactly where the wiggle stopped, it is probably best to simply do this with an extra keyframe (i.e. make the position keyframe "jump" from its original position to the position where the wiggle ended) ...

What about 1) compute the line that is perpendicular to the tangents of A 2) compute the line that is perpendicular to the tangents of B 3) the two lines from 1) and 2) intersect in exactly one point which is probably the point you are looking for Before you think about how to implement this as a script, I recommend to think about whether this is exactly what you need. Because when you say you need the middle of a circle but also have very different shapes, a big question is what you actually want to compute exactly. ... View more

As Dan said, the time remapping + mute is probably the only thing that can be done. You can use the Time Remap At Marker iExpression for that. Among other things, it can repeat a particular sound at each marker and also does the audio muting to avoid the "rewind noise": Time Remap at Marker Expression | mamoworld ... View more

Lasergod schrieb: But is there a function where I can define a number of keys, this function looks for the length of the composition, divides the length with the number of keys, and places the keys like this, that every key has exactly the same duration? There is no ready to use function for this, but you can access the duration of a comp with comp.duration // inherited from AVItem and you can set keyframes for properties with property.setValuesAtTimes(timesArray,valuesArray); Hence, you can write such a function yourself. ...

Yes, it is really a pity that it is not possible. In KeyTweak I used some workaround to make users specify certain mask vertices. When you click on its "select mask/shape vertices" button, a dialog opens that allows you to choose a range of vertices. Simultaneously, a temporary solid layer with circle effects is created that highlights the chosen vertices. This is far from convenient but the best workaround I found. ... View more

I don't have Element 3D and therefore I don't know exactly which parameters it has, but to connect any 3D point parameter to the position of a null, you can use the pick-whip or alternatively the Simple Link 3D iExpression. If Element 3D has three separate parameters for x, y and z, you also use the pick-whip or use the Simple Link 1D iExpression. If you use the Simple Link 1D to link to a 3D property (like the position of a 3D null), in the options of the link you find a dropdown to choose whether you want to link to the X-value, the Y-value or the Z-value. Hence, you can simply apply the link to all the properties (x,y and z) and each time choose the corresponding option. ... View more

Here is a tutorial showing how to create these kinds of animations in sync with your audio with iExpressions Animating to Music After Effects tutorial by Eran Stern You can create a hand for your meter as a simple solid layer with a mask.
