Seedance Skill

Turn any app into a cinematic motion graphics promo video using AI.

Seedance Skill is a Claude Code skill that generates glossy liquid glass motion graphics videos using ByteDance's Seedance 2.0 model via Fal AI. Give it screenshots of any app, and it produces Apple-keynote-quality promo clips.

Examples
