Video editing is the process of manipulating and rearranging video footage, audio, and images to create a new and cohesive final product. This can involve cutting and trimming clips to remove unwanted footage or improve pacing, adding transitions and effects to enhance visual interest, and adjusting color, brightness, and contrast to achieve a desired look. Video editing can also involve adding music, sound effects, voiceovers, and other audio elements to improve the overall experience for viewers.
