ExtendScript: send clip Blob from jsx to js

[SultanDino]

Is it possible to create blobs in jsx and send them to js?

What I am trying to do is get the clips from the timeline and display them in the panel with <video> tag. The user can then play each clip in the panel and pause (make a selection) as a image which will then be uploaded to the server as a thumbnail.

Seems like Blob is not supported in jsx. Is there a way to at least use URL.createObjectURL() inside jsx and use that in the js panel?

Any other suggestions on how to get this working?

ExtendScript does not support 'blobs', although you can pass Strings between a panel's JavaScript and ExtendScript layers, as demonstrated by PProPanel.

Thanks for the confirmation.
I have solved this by using node.js, I pass the paths of the clips from jsx to js and in js I read those files with fs (node)
