Video editing involves manipulating and rearranging video clips and audio to create a new work. It includes tasks like rearranging clips, applying effects, and creating transitions between clips. Various techniques like shot/reverse shot, match cuts, and crosscutting are used to maintain continuity and clear narrative. Transitions between scenes are also important, and can involve fading, inserting background music, or different types of visual transitions. Proper editing techniques and pacing help tell the story smoothly.
