Add video with black bars
Add a video where you'd like to remove black bars. The software will ask you if you'd like to auto-crop black bars from all your files. Choose "Delete black bars".
If you chose "Keep black bars" by mistake or closed this form, go to Options ->Black bars and change your choice.
Black bars will be removed automatically. To save the changes, convert the video. Choose a format, then preset "Same as source", and hit "Convert".
