Hey Julian, how did you used Stereo Mixer? Based on the user input, by setting value to 0..100?
In addition, by saying it does not work, do you mean audio is not affected at all, or are there other issues?

Assuming that framerates of your loop comps are all the same and matches main comp:
1. Make background loops comp length to be a single loop long. Lets say, 5s.
2. In the main comp, apply Time Remapping.
3. Add slider control into expression field.
4. Animate the slider. Set keyframes of the same value at different time marks to create a pause.Find out more:

Hey Mohamed, nice way on doing the tutorial with that ‘problem related’ intro. Enjoyed watching it !

Stephan – if manually, then its just an addition of a number like ‘time + 45’, etc.
If more dynamically, you could also multiply it by an index, or random number generator – there are many ways on doing this, depending on your needs !

Hey Stephan, maybe it sounds too simple, but adding minus in front ‘-time’ will go other way around. Unless, its not what you are looking for!

Hey Davide, thanks for the sample project.
I reviewed it and it really behaves strangely. The most importantly, when I create new rectangle layer, set its anchor and animate rect size – it attaches without any problems.
Accordingly, maybe you someone differently created Rectangle shape, that its attributes are missing? For example, there are no transformation group. You had an empty shape layer, and then added rectangular path – not an actual rectangle.
With that in mind please try to use rectangle tool to draw the shape – it should solve this case.
But yeah, that one is interesting! The difference between Rectangle Path 1 vs Rectangle 1 alone, its just procedure path, without all other attributes which has Rectangle group. Hope this helps!

Hey Davide, can you please do the following:
1. Let us know where you set a keyframe – is it on the size of rectangle shape or anywhere else?
2. What in particular does not work?
3. Ideally, share project file with the problematic comp.Cheers!

Hey Al,
welcome to the idea of scripting world! To begin with, this is as simple as:
[propertyPath].expression = "expression goes here";
Which, in full scripting language would look something like this:
app.project.item(1).layer("Shape Layer 1").property("ADBE Root Vectors Group").property("ADBE Vector Group").property("ADBE Vectors Group").property("ADBE Vector Graphic - Stroke").property("ADBE Vector Stroke Width").expression = "time*5"Now with further digging into this – you would need to do the following:
1. Select the layer to process.
2. Run FOR loop to skim through shape’s contents, to find out which has strokes, etc.
3. Apply expressions to the ones which does.To make your life a lot easier, download this script called GimmePropPath. Run the script, select property you want to access and hit ‘Get Property Path’. This will give you a sense how to reach items and from that point, it will be easier.
BUT, you still need to understand the whole hierarchy of items through scripting. So take this shortcut as a helper, not a full lead 🙂

Hello Maria, are you really sure its an issue of the track matte? The thing is – I never experienced any problems with it, and based on the supported features list, there shouldn’t be any.
What else might be the case – its the way how shapes are grouped in the shape layers. Be aware:
1. If you converted .ai files to shapes, chances are high that inner structure of shapes group must be cleaned up.
2. If your shape layers has merge paths inside – it will fail too. Workarounds should be used to avoid this.If none of the above valid, make sure no other non-supported feature is not used. Alpha Track Mattes shouldn’t cause issues. Let us know how it turns out!

Aqeel – did it helped and you managed to sort it out or I just created confusion? (:
In case if option NR 2 – just add your test project with what animation you have applied already and it will be the easiest way to help you get through.
