Media codes are techniques and conventions that help to give meaning and engage audience.
Technical codes - use of equipment or techniques in specific ways.
Symboliccodes - what something represents.
Writtencodes - the language used, printed or spoken.
Technical codes are specific to the type of media being created. In film, these include lighting techniques, camera movement, and audio techniques.
Symbolic codes are not a part of the media product, but of culture and experience. They are about what something represents, symbolises or means. Examples are body language and colour.
Written codes apply to a written text or dialogue.
Mise-en-scene refers to everything the camera sees.
Transitions connect two different shots together, created in post-production.
