Here is a detailed description of the video: The video shows a person pressing a green button to open a door, likely on a ferry or similar vessel. The door is clear, allowing a view of the exterior, which features an expanse of water and land in the distance. The deck outside the door is blue with white railing. A sign above the button is written in Malay, indicating it's a button to open the door. Once the button is pressed, the sliding door opens automatically, revealing the view from the deck.
