well, I'll be brief but first page of that gui you point it to the .exe files for whatever programs you're going to use with it, you also select output destination and select input file
go to the tab for program you want to use, first load the file, I know you loaded on first page but now load it on the tab, then select all your settings, click add to batch listing, when you're done, go to batch listing tab, click run batch, you'll notice a small black cmd promt will start running, it will not look like it's doing much, but it is working, the cmd promt will disappear when process is completed
