The introduction in a rhetorical analysis paper can be brief, but should contain a few basic elements. If you were analyzing a piece of literature, in the first sentence, you would introduce the author's credentials, the author's first and last name, the type of literary piece, the title, and the the author's subject.
An example of this can be: Victorian novelist, Charles Dickens, in his novel, "A Christmas Carol," captures a tale of Christmas and a change of heart.
Since your rhetorical analysis paper will be analyzing a video you produced, the first sentence of your introduction will be similar, however, it will include the following:
1) Your credentials, being producers/directors of the video.
2) The first and last names of those who created the video, or if you've assigned producer or director to certain individuals and want to give more precedence to one of those individuals, then go ahead and just list that one individual. For instance, your first sentence could start like this: Director, Sam Smith, through his video.....
3) Include the title of your video parodying soap operas. If you have not thought of a title for it, do so now. It will make referencing the video in your paper a lot easier.
4) Include the subject of your video.
Next, the second sentence of your introduction should state the purpose of the piece you are analyzing. Using our Charles Dickens example, we could add: Dickens's purpose is to create a story that challenges a person's life choices and actions. Your second sentence will say something more about the purpose of your parody. It will introduce what you will be analyzing.
Finally, your third sentence will say something about the audience of the piece you are analyzing. In particular, your third sentence will state how the soap opera parody shows its audience that violence influences younger viewers.
