To create a storyboard you have to first diagram the pieces of your film. For each type of video project this will be different, but essentially there are some very specific story elements that are true of all media. You begin with establishing action or sequences, which are set to either identify the characters or the event that will be taking place. Then you give shots of the beginning of the story, which can be interpreted as the rising action. This may be your son getting ready for his football game. In that case you would show shots of him practicing, getting ready, and heading to the field. The middle is where the main action takes place, and most likely where most of your shots will be. The end is the summation of the event or story, where the characters are re-established and shots focus on them removing themselves from the action that has just taken place. You should also put in second unit or B-roll shots, such as cut always to images that are not directly part of the storytelling.
