Camera Shots:
The main three types of camera shots used are long, mid and close up shots; long shots are used to help show location and can emphasise a location's size, mid shots are used to help show the artist clearly, giving you chance to know the look and feel of the artist and lastly close up shots are used to emphasis emotion and to show the lip syncing 

Camera Movements:
Camera shots are used to trace the steps of the artist or the actors they may have chosen to use within the storyline. Camera shots such as tilts, pans, tracks and crane shots are used.
Conventions can alter with genre, such as with a hip-pop song the shots will more than likely be very still and simple, however with a heavier song, the camera will be more slack and realistic, this is because the camera usually moves along  with the beat of the song .

Mise-En-Scene:
Mise-en-scene is  everything within the shot, such as:
Lighting
Props
Location
Costume

Lighting is important as you are able to have lighting to represent or emphasis a certain aspect of your video or you could use it to set a mood, such as the use of black and white in 'cheapthrills' by sia which gives it a retro feel

Location usually changes depending on genre, such as heavy metal music will usually use quite run down or derelict style buildings, however dance music will use places such as nightclubs or large party type venues, this represents the type of music they play as it also gives off a sense of emotion and presence.

Costume depends on the type of song, this could be done to a theme, such as a futuristic theme such as Ariana Grande Break Free ' or a 80's theme for example 'Uptown Funk' by Bruno Mars, however, sometimes they will just wear their normal clothes as they like to keep themselves real and don't like to dress up, 

Editing:
Editing also changes with genre, however, one rule that always tends to apply to conventional music videos, and that is editing to the beat of the music, this makes the video catchier and  gives it an overall more professional look. They will also really only tend to use straight cuts, this is because they want the music video to be strong and punchy for the viewer.
