Hi all.

There is such attribute app.project.item(index).propertyGroupSpec.numProperties .

How to go through the branches of this array and get all the properties of the lower level

where there are temporary keys for changing the current property,

to get the string trace content:

s

property number.sub-property number. key( time, value)

Scripting

I think there is no efficient way to filter properties to obtain only keyframed ones. You have to go for the slow approach to iterate over all properties and check numKeys for all of them to see if they are keyframed.

what does the slow approach mean? Is there a straight forward way do this trick using match names for each type of layer in the composition and for each property. but for this you need to create arrays of existing match names. is there really no way to avoid creating such arrays

You can loop over all children of a property group like this:

 for (var i = 1; i <= propertyGoup.numProperties; i++) {
        // do something with propertyGoup(i) here
    }

Do it recursively to decent to all leaves of the tree.
