Rotoscope is the easiest tool to create hand-drawn renditions of videos by tracing over each frame in the video and then exporting to a video file.

Rotoscope uses Windows Ink to let you draw with colored pens, pencils, and highlighters in a pen and touch-friendly interface, rapidly inking each frame of the video as you go. The resulting animation takes the audio from the orignial video and mixes it with the inked video frames.
