After specifying all the settings, you can click the Run/Convert/Start button 
on the bottom-right of the program UI to start the conversion. Soon you will see the window below:
The Conversion window displays task list and progress information including Time elapsed, Time left, Generated size, and Estimated size. You can click “Pause” to suspend or “Stop” to cancel the conversion at half way.
Time elapse: The time has been used for conversion.
Time left: The rest time for conversion.
In case of an error occurs during conversion, please click “View log” to check detailed error report.
The consuming time grows with generated file size. If conversion takes long time, you can set auto shut down by checking the box of “Shut down computer after conversion".
