Read FootageItem source file duration in ExtendScript.

[finnf46146287]

I have a question about jsx scripts in after effects.
Do you know any way to access the duration/length of the original source clip from inside the extendscript environment?
something like app.project.item(x).source.duration?

Or does anyone have an idea how to read the EXIF data of a source clip?

Well, there's this app.project.item(X).duration; 

Not sure about EXIF data though.

thats just the length of the layer. i am looking for the length of the sourced file.

item.duration returns a duration of an item. There's no such concept as a length in After Effects.

solved it by building a cli  script and `system.callSystem()` it
