How to Execute ExtendScript in Premiere Pro

Executing scripts from within CEP panels is the recommended approach. It is also possible to invoke scripts from within ExtendScript Toolkit (ESTK), but that’s not a user-friendly approach for most workflows. Also, with additional configuration work, it’s possible to pass scripts to Premiere Pro on a command line. This is not recommended, as behavior varies across platforms, and preliminary configuration is necessary before such execution is enabled.

Use ESTK for development and debugging; for deployed workflows, stick with panels whenever possible.
