Lip dubs are a new form of music-video expression. In technical terms, a lip dub is a video that combines lip synching and audio dubbing to make a music video. It is made by filming a group of people lip synching while listening to a song and then dubbing it in post editing with the original audio of the song.
The most popular lip dubs are done in a single unedited shot that often travels through different rooms and situations in, say, an office building or a school campus.
Tom Johnson, a technical writer who blogs about Web 2.0′s effect on communication, describes a good lip dub as having the characteristics, or at least the appearance, of:[1]
- Spontaneity: “It appears as if someone thought up the idea on the spot, pulled out their personal video camera, and said hey everyone, let’s all lip sync this song.”
- Authenticity: The people, production and situation appear real.
- Participation: “The video doesn’t consist of one person’s spectacular lip sync, but that of a group, all participating together in this one spontaneous effort, which seems to communicate the attitude and mood of the song.”
- Fun: the people in the video are having a lot of fun.
Some French and Canadian schools have done rather original lib dubs, among others EM Lyon, ESSEC, HEC Montréal, HEC Paris, and Sciences Po Paris.
