A lip dub is a type of video that combines lip synching and audio dubbing to make a music video. It is made by filming individuals or a group of people lip synching while listening to a song or any recorded audio then dubbing over it in post editing with the original audio of the song. There is often some form of mobile audio device used such as an MP3 player. Often they look like simple music videos, although many involve a lot of preparation and production. Lip dubs are done in a single unedited shot that often travel through different rooms and situations within a building. They have become popular with the advent of mass participatory video content sites like YouTube.
Although lip dubbing in music videos was not a new concept (eg. Spice Girls "Wannabe" [May 1996]), Jake Lodwick, the co-founder of Vimeo, coined the term "lip dubbing" on December 14, 2006, in a video entitled Lip Dubbing: Endless Dream. In the video's description, he wrote, "I walked around with a song playing in my headphones, and recorded myself singing. When I got home I opened it in iMovie and added an MP3 of the actual song, and synchronized it with my video. Is there a name for this? If not, I suggest 'lip dubbing'." Lodwick also directed the "Flagpole Sitta" "office lip dub" in April 2007 which The Washington Post covered.
Since then, dozens of lip dubs have been coordinated around the world predominantly by university students. After L'Université du Québec à Montréal (UQAM) and the crew of Today Show produced a lip dub to The Black Eyed Peas' "I Gotta Feeling" in 2009, the viral video phenomenon gained international acclaim.
The use of camera stabilization hardware is commonly used to provide an easy to watch and smooth final product.
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 spontaneity, authenticity, group participation and fun.
