The most common shots in music videos are long shots that show the artist and surroundings to portray the artist as powerful within the scene. There are also close-ups to show attractiveness or style and medium shots of the artist with others.
A base track is a full-length clip filmed from different angles and movements to synchronize easily to the song audio when editing. Most music videos contain base tracks because it allows cutting and syncing to the audio at any point.
Markers are used to lip sync by placing one at the point where audio and lips match in a base track clip. The audio is then lined up perfectly by matching the marker positions.
