I had to question why an musician would choose to debut their own piece of art through the form of a one shot music video. They seemed, by nature, to be much more difficult than being able to utilize different cuts to get the message across to the audience. Later, I realized that there are actually many benefits of the one shot music video.
One benefit is that it has the potential to be cheaper and easier to make while still being engaging. Bob Dylan famously did this through his music video for "Subterranean Homesick Blues," in which he stands in an alley way and holds up signs for each of his lyrics as his song plays. Though it is pretty simple, the video is actually very interesting to watch, and forces the audience to think about the lyrics and meaning of the song. Watch it here:
Another case for the one shot music video is that it allows quite the opposite- an extravagant display of lighting, effects, and action, all planned out until the last second, as with LCD Soundsystem's "All My Friends"
...Or a meticulously choreographed dance routine, like in Feist's "1234."
I realize now that one shot music videos not only give the filmmaker lots of creative freedom, but perhaps even allows the content of the video and song to resonate with the audience more, as each movement is clearly methodically planned and coordinated.
