Wan 2.5 Preview Visual Action: A highly detailed close-up of dense, swirling, yellowish-orange toxic cloud cover. The thick gases churn, roll, and mix dynamically like thick liquid or smoke billowing across the planet's surface. Cinematic Camera Movement: A slow, creeping tilt-down following the downward flow of the heavy clouds. Audio/Foley: Continuous, heavy, gusting winds mixed with a subtle, acidic fizzing and bubbling sound. No music, only sound effects and foley.
