Handwritten Sketch Style Countdown Timer with Grunge Overlay

This animated countdown features numbers from 30 to 1, dynamically appearing with a vibrant lime green, handwritten sketch animation. Each digit is drawn with a fluid and organic motion, giving the impression of a live sketch. The visuals are set against a dark background, subtly enhanced by a film grain and grunge overlay that introduces a raw, vintage texture. This unique and artistic visual effect serves as an engaging opener, transition, or event timer, suitable for various video projects. The clip is designed with an alpha channel, allowing for seamless integration over existing footage.
