Sketch to Motion

Convert a static image into a smooth drawing animation using Manim.

This project takes a doodle, photo, or sketch, converts it into an SVG vector graphic, and renders it into an animated MP4 video with Manim.
It also prepends the last frame to the start of the video, creating a short pause for a more polished look.
