If you want to get the picture that will fill in entire screen of the monitor from a wide-screen movie, it isn't enough to remove the black bars. The video will be still wide screen.
The following steps will help you to resize the picture of the video. Add your original file and choose the profile you want to convert to. Let's take for example AVI. After you click on the button 'to AVI' you get a new window. Click on the blue cog wheel there (settings) and you get another window opened. There click on Frame size -> custom, Adjustment -> Original. Once you click on the original button you see additional window. There are pictures which can help you to make the right choice. We recommend to choose 'Zoom&Crop'.
