The document discusses codes and conventions of editing used in three TV dramas: EastEnders, The Bill, and Doctor Who. It analyzes the editing techniques like match cuts, line cuts, jump cuts used in sample clips from each show. For EastEnders, match cuts are used in conversations and jump cuts between scenes. The Bill uses line cuts in conversations and jump cuts when moving between locations. Doctor Who uses line cuts when characters move and conversations, with potential for invisible editing due to engagement. The pace and tempo of clips in each show is also examined.
