The user interface was made to allow for both simple and complex conversion jobs. To perform a conversion task, first specify it in the upper area of the user interface, and then optionally click the Add button (in the upper toolbar) to add it to the conversion task list. If you are only going to have one conversion task, then don't bother with the Add button.
When you are ready to begin you can press the Convert (or F5) button to initiate the conversion job.
You can build conversion jobs, consisting of one or more conversion tasks, which may be saved, restored, and edited. Once saved, they may also be specified and run from the command line, making automating complex tasks a snap. See the File menu for saving and restoring conversion jobs.
Once a conversion job is complete, you can view the status of the process in the Log Tab located near the bottom of the user interface. Any error messages will show up here.
