Animated Rolling Fog Effect with Alpha Channel

This animated clip features a realistic, misty fog effect that rolls dynamically upwards from the bottom of the frame, eventually dissipating to reveal the background. Against a dark backdrop, the translucent white and grey fog creates an ethereal and mysterious atmosphere. Designed for versatile use, this effect can serve as a compelling overlay, a dramatic transition between scenes, or an atmospheric background. Its included alpha channel ensures seamless compositing over any footage or graphic, adding depth and intrigue to horror, fantasy, or cinematic projects, or simply enhancing any visual with a touch of natural, fluid motion.
