Does Photoshop support creating and manipulating a Video Timeline in javascript?

Hi, I have over 1000 photos that each have 30-40 layers that I want to animate - for instance, with photo1, show 3 of 30 layers, animate those layers, then export to an MPEG file… then pick a different 3 layers in photo1 and do the same, etc.. up to 30 layers just for photo1. Then do the same for all 1000 photos.. With all the photos I have, so many layers for each and so many animations to create I was hoping to create a javascript to do all this work of creating a video timeline, adding layers, set timeline positions/durations, etc… then I will review and save each animation myself (I’ve learned I can’t export to an mpeg file via scripting - bummer). I asked ChatGPT and it provided sample code showing that it’s possible to create a timeline, create video layers, move layers around, set durations, etc… but I get an error right after creating a timeline object when trying to add a layer to the object - e.g: var doc = app.activeDocument; var timeline = doc.timeline; timeline = .timeline.addLayer (myLayerObjectHandle); //this is the line I get an error The error I get is “undefined is not an object” on the 3rd line. I’ve also tried: var doc = app.activeDocument; var timeline = doc.timeline; var videoTrack = timline.videoTracks.add(); //same error here In chat messaging with Adobe support they say it IS possible but they didn’t have samples to show or links to developer docs. I don’t mind using a different app perhaps Affect Effect? but really hoping to use Photoshop. In looking at Adobes developer object model, I don’t see a doc reference for a timeline method/function off either the app or document(s) objects. Any help here would be fantastic. Thank you
