Preview, rendering and export
A live browser preview is not a rendered video. The hosted MCP service currently has no validated native Manim worker.
Check /mcp for this deployment's connection status. Widget and download capabilities depend on the client; authenticated ChatGPT host acceptance is still pending.
Browser preview and video
The widget previews saved 2D/3D scenes with the editor renderer. Eligible scenes can export a local H.264 MP4, with WebM fallback in compatible browsers. Widget capture is limited to 30 seconds, 30 fps and 720p-equivalent pixels; formula, media and audio layers export through the full editor.
Native output
For native Manim video today, open the project in the browser editor and use its supported Desktop Render Agent workflow. The MCP hosted service does not start a native job.
Desktop Render Agent guideDownload and plan checks
Before export the server rechecks ownership, revision, current plan and watermark requirements. Downloads use the host's file-download capability. If a host cannot download files, continue in the editor. Free exports retain the brand watermark; WebM fallback may lack finite duration metadata.
