Automated batch processing is supported for up to 20 movies per user click.
Amazon Assisted, Suppress Browser, and Batch Process All Movies options must all be selected in the Advanced panel to enable batch processing. Once those are set, clicking on any film name will start automated processing.
When batch processing is active, only unprocessed folders will be listed. Turning off "Show only unprocessed folders" disables batch mode.
I have purposely limited the number the number of movie folders processed in a batch to avoid overloading the Amazon servers with large batch jobs. You can, of course, start another batch by clicking on another movie name.
It's been pretty nifty watching wallpapers get generated without user intervention. For the most part it appears to work, but keep an eye on the results as the program works.
