There is no way to automatically accomplish all of this with a keystroke or two in Premiere Elements.
Though I don't know what you mean by "Call a few external command line programs to prepare some media files" and "Call a final external command line program".
To clarify, is there a way to:
1.) Automate/script the Elements frontend? i.e., place media on the canvas, clip, etc.
2.) Invoke an external program command line program from within the program?
The program includes tools for creating InstantMovies and for building Video Stories from templates.
But no way to script entire processes.
Ok, thanks for the clarification.
I am looking to automate a moderately complex workflow in Adobe Premier Elements 11.
Have you seen this work in other editors?
I've managed to (mostly) automate this using QA tools, but was hoping there would be a tighter way.
