Turning a Talking-Head Video into a Line-Art Animation Explainer

Turn an 83-second vertical talking-head video into a line-art animation explainer: shrink the portrait to a circular picture-in-picture in the bottom-right corner, and replace the main frame with line-art B-roll that switches to match the narration — about 30 shots, keeping the original audio, original subtitles and runtime unchanged, for a final cut of about 84 seconds. Suited to repackaging talking-head knowledge videos and short-form explainer clips for creators.
