Remotion

Remotion is a framework for making real MP4 videos with a software framework called React, so the code is the source of truth. You can install Remotion in any coding agent (e.g. Claude Code or Codex), then use prompting to describe your ideal video output. The agent writes React that renders to a real MP4 video. Remotion Agent Skills inject best practices into the agent, and Remotion Studio lets you make visual drag-and-drop tweaks that save back to code.

Remotion is great for animated charts, Venn diagrams, web graphics, or even launch videos! The Anthropic team has used to to announce several features, or to animate slides from conference talks. The best prompting move is to hand the agent an inspiration image first with minimal instructions, then iterate; front-loading detail just invites misinterpretation. Feed real data for accurate charts. Skip it, or expect more effort, for complex hand-drawn or arrow-heavy designs. The agent can't ingest existing videos directly (it extracts frames with FFmpeg to reference a clip), and polished pro results still assume you know the tools and can spend real time. Note Remotion's special license, which requires a company license in some cases.
