A video shows a traditional guard changing ceremony in Seoul, South Korea. The camera faces a group of guards in red robes with blue sashes, conical hats, and feathers, walking in formation on a stone courtyard. In the background, a large, traditional Korean palace building stands under a clear blue sky. Other people in historical costumes are scattered around the courtyard, and a few tourists watch. The sound of a drum can be heard. The scene is brightly lit with strong shadows.
