Framing to create meaning

Grizzly Man (Herzog, 2005) is a docudrama using the following codes and conventions:

Voice over/Presenter – This keeps the audience updated with the images and videos while telling a story.

Handheld camera – This is used when whoever is in the docudrama is on the move, it keeps the audience ready for the next piece of action.

Poor sound or lighting – This shows that it is not a staged docudrama, it is showing real events. You can’t always have a setup. This makes it more believable for the audience.

Our documentary is called Bullying: The impact and it is going to be a 6 minute documentary about bullying and the impact that it can have on not only school children but also adults in the workplace some of the codes and conventions that we are going to be using are:
