Revideo

Revideo is the open-source framework for programmatic video editing: create video templates in TypeScript and render them via an API.

This is video infrastructure for developers: Revideo, an open-source framework, lets you build complex video workflows at scale. You define video templates using TypeScript, then leverage the API to render them programmatically with dynamic data inputs (text, images, complex structures). Based on the HTML Canvas API (forked from Motion Canvas), the project provides a React player component for instant browser previews and exports final output to MP4. Developers use it to automate short-form content creation, build web-based video editors, and programmatically generate hundreds of video variations for A/B testing marketing campaigns.
