A minute and a half of high fantasy: a queen in gold and blue armour above a sunlit harbour city, ranks of helmeted soldiers, ships that fly over the sea, a giant mechanical walker and a dragon resting under her hand. Warm gold and pale marble run through every shot, which is what makes dozens of separate scenes feel like one world.
Generate each beat as its own shot and keep the same wording for the costume, the city and the colour palette in every prompt. Using a still of your hero as an image-to-video start frame helps the face and armour stay the same from scene to scene.
