This video analyzes a "second a day" campaign film that shows a young girl's life changing from happiness to sadness over time through short, 1-second clips. The clips use various camera angles and locations to depict her normal life that is then turned upside down. Throughout the video, mise-en-scene and sound are used to highlight her changing emotions and surroundings, from joy with family and friends to isolation, sickness, and sadness in a hospital. Editing techniques like jump cuts, fading, and logos connect the 1-second clips to tell the emotional story of how anyone's life can change in an instant.
