Premiere Pro 15 scripting question

[Thomas Polson]

I want to creat a script that will run premiere with a specific projec file, exectute an extend script, then close premiere.

Is that possible?

There's a little-known way to pass command line arguments into Premiere to run a script, but it's very limited and will only work in some cases, see more info here:

Your other option is more complex, basically write a standalone app and a headless CEP Extension panel set to auto start. Have the Standalone app launch Premiere and establish a WebSocket connection with the headless auto-start CEP panel. The CEP panel can then send ExtendScript commands to modify and save the file, and then close the app.

Justin is correct; while it's possible to invoke ExtendScripts from a command line, that process is unsupported and not at all recommended. CEP panels are the right approach.
