Realistic Smoke and Fog Overlay Element

This animated visual effect features a dense, realistic simulation of smoke and fog, dynamically expanding and dispersing across the frame. The volumetric clouds of white and gray vapor billow and swirl, creating a powerful atmospheric presence. Designed with an alpha channel, this effect offers seamless integration into various video projects, making it ideal for adding depth, mystery, or impact to scenes. It functions effectively as a transition element to reveal or obscure content, or as a subtle background texture to enhance mood and environment.
