Hello!
I saw your edit, but I may have a suggestion for you as well, if you go to options, you will see a place where you can 'Place your output file'. For now, until you get familiar with the program, I suggest you create a folder on your desktop, and call it VideoPad. Have the output set to this folder on the desktop, and then make new folders for each new project. It's kinda like filing folders for each time you are doing the editing. That way when you need to come back to it, you will easily see what has been done and if was done correctly. Fast and easy.
Hope this helps!
