Hi Robert, while you are in the Gallery and looking at video files, pick out the one which you want to delete and put your finger on it for about two seconds. Basically, press and hold it until a trash can icon which stands for Delete appears on the screen. As an alternative, you may be able to delete a video from the gallery by opening up the thumbnail view, pressing the menu button, and looking for an option that says Delete. Try it and see if it works!
