Editing involves juxtaposing different shots to construct a narrative and set tone. When analyzing editing, three key things to look for are screen time of characters, pace created by cutting rate, and perspective conveyed through shot selection. There are different types of edits including cuts, transitions between shots, variation in speed, and special effects. Editing is important as it connects shots into a coherent sequence to convey meaning, with implications of the edit choices, and works together with other elements like sound to tell the story.
