PRO NEW video v2.0.0 Remotion

Explainer Motion

A topic becomes a narrated, animated explainer.

Give the skill a topic, a doc or a rough idea and it builds a complete explainer: research notes, a concise script, a voiceover, animated scenes and captions. It is designed for concepts that are easier to show than to describe, and it exports a landscape master plus a vertical edit for social.
