Codes are a way of creating meaning. The following are the different types of codes;
- Technical codes - This includes the way in which text is technically constructed camera angles, framing, typography etc.
- verbal codes - These are codes that can be decoded on a mainly connotational level - drawn upon our experience and understanding of other media texts, (cultural frame reference).
In media studies, a message is often described as being 'encoded' from the sender (producer) and the 'decoded' by the reciever.
For semiotics, a code is the framework, a learned and shared conceptual connection at work in all uses of signs.
Conventions are the commonly understand ways of doing things in a media text. The use of conventions in a music video help the audience to identify the genre of the song and artist.
For example, within the genre of Hip Hop, music videos tend to include images that display wealth, superior (linking into star theory) and sexually objectifying. This is shown in the example below in 50 Cent's "Candy Shop".
Wealth is shown through the artist wearing expensive jewellery and clothing, such as a fur coat. Also, 50 Cent stepping out of an up-market car helps to show he is very well off and has a lot of money. Hip Hop artists' tend to do this in their music videos as it shows their audience that 'they have made it', and are no longer 'suffering'.
Whereas, in the popular music genre Pop, these music videos care commonly quite child friendly. This shown through very 'clean' and positive lyrics along with reasonably young and vibrant artists.
For example, in Katy Perry's "Firework" which is seen to be an inspiring song which matched quite nicely with its music video. Katy Perry is shown to be a sensible and attractive young women, one arguably suitable to be a role model to her community or young people. Also, by having numerous vibrant and bright colours throughout the video, helps to connote happiness, a common convention within this music genre.
