Cutting to the beat

Playback and lip sync
a term that refers to when (during a performance) a musical group play a prerecorded track and lip syncs on the stage
the new rock group used playback instead of actually singing/performing the song on stage. as this gives more way of letting the group dance and sing while dancing and singing at the same time as he or she can just mouth the words also if this is done then any wind and any other sound effects uncontrollable of the artists hands can be removed if they are recored in a studio and they lip synch the words.  https://www.youtube.com/watch?v=Yc7-krRX8uA
as this is apparent in the song SING by Pentatonix as most if not all shots take place outside of a studio and there is no natural or environment sounds such as cars or wind

Camera movements
Just like in any form of video media there will always be certain camera movements that are used for different reasons; an establishing show will generally set the scene at the beginning; a long show will normally set out the location of a closer scene, so the audience have a better understanding of the atmosphere;

Camera angles
Just like movements, camera angles makes a huge impact on the meaning and style of the music video, Wherever a camera is placed can show the bower of the artists/ characters. or sometimes it can show an exact location from where we should be seeing it. by choosing different angles the viewers have a different view of the action which makes it more interesting and everybody will have their own way of watching it. - https://www.youtube.com/watch?v=1AJmKkU5POA

Chroma key
Chroma key effects are when music videos are shot in front of a green screen. this means that a block colour behind the artists and is replaced by another picture / video. sometimes the quality doesn't always look as good if the background is of a specific location but they are sometimes used for upbeat dance. but in the case of eminems - like toy soldiers it is used for a different reason it is to set the stage for each part and gives a background for the song and visual
