Media Codes

Media codes are the techniques and conventions that producers use to convey meaning, create impact and engage an audience. They are the visual, audio and written ‘language’ of a media product.

The three types

There are three broad types. Technical codes are to do with how the product is made and presented; in film and television they include transitions and sound. Symbolic codes rely on associations and culture, such as the meaning of a gesture or a colour. Written codes cover text and dialogue, including typography.

Codes are chosen deliberately, so they should suit the audience, purpose and context of the product.

The same code can create different effects depending on how it is used: a bold font might make a warning stand out on a safety notice, while the same bold font on a birthday card might feel cheerful and loud. A code is not automatically good or bad; what matters is whether it fits the job.

Codes also work together with content. It is the combination that creates the overall meaning, impact and engagement, rather than each code working in isolation. A trailer for a school play, for example, could combine a cross-fade between two scenes, a whispered line of dialogue and a jagged title font; each choice supports the others to build a tense, mysterious mood and make the audience curious.

Using more codes does not automatically make a product better: they must reinforce the intended message and suit the audience, purpose and context.

A code only works when the audience reads it, so naming it is not enough on its own. Instead of writing that a poster uses a large title, explain that the large title is the first thing you notice, so the event name is clear even from a distance.
