Conventions of a Music Video
Almost every mainstream song these days are having music videos made for them. Due to this expectation, appearing in their music videos is now a regular responsibility for bands and artists.
One of the simplistic, and least appreciated conventions of a music video is that the visuals will usually illiterate the lyrics of the song. Where some depict the deeper meaning of the song, others show the lyrics almost word for word, such as Riptide by Vance Joy.
Another key aspect of a music video is also present in this video, that of lip-syncing. Most often undetectable, as the singers themselves typically appear singing, but in this case it is especially noticeable as the song is being lip-synced by a women, where as the singer is male. This is not uncommon, it is also seen is such videos as I really like you by Carly Rae Jepsen.
One of the most often seen themes in music videos as well as lip-syncing is the band playing their instruments. This is one of the simplest types of music videos to produce, as the directors merely need the band to play the song and record it. Sometimes the narrative is lacking, as they just use the concert with no actual media devices used, or even film the artist's concert such as Taylor Swift's New Romantic. A better example of a concert within a music video is It's My Life by Bon Jovi.
This music video applies a narrative involving a concert, the narrative being that a fan is contacted by a friend that the concert is happening and he needs to get there as quickly as possible. This means they can create cuts between the fan and the concert until he gets there at the end of the video.
