Ground in NotebookLM. Animate in Claude Design. Export Clean MP4.

Who is this guide for?

How do you export a Claude Design video as MP4?

The short answer. Claude Design has no native MP4 export. The fastest working path: click Share inside Claude Design to generate a public URL, paste that URL into claude2video.com (free, no signup), and download the MP4. Frame-perfect, server-rendered, usually under a minute. See all 3 methods →

NotebookLM Video Overview vs Cinematic Video Overview — what's the difference?

Standard is a narrated slideshow, available on all plans in 80+ languages. Cinematic is a fluid animated video built by Gemini 3 + Nano Banana Pro + Veo 3, launched March 2026 — English only, 18+, Google AI Ultra plan only ($249.99/mo), 20 generations per day. Both are grounded in your sources. Method A details →

Is claude2video.com safe to use with my Claude Design content?

Per the operator's published threat model: the share URL carries an auth token, claude2video opens it once in a headless browser, captures frames, and does not store source content. Threat model is identical to sharing the link with anyone else. For client-confidential work, use Method C (local Remotion/FFmpeg) instead. Method B details →

Why this stack is the 2026 default for grounded video

Three things changed in the last 90 days that make this workflow possible. First, NotebookLM launched Cinematic Video Overviews in March — animated videos generated by Gemini 3, Nano Banana Pro, and Veo 3 working together, with Gemini acting as creative director. Second, Anthropic launched Claude Design on April 17, powered by Claude Opus 4.7, capable of generating animated HTML/CSS/SVG artifacts from a prompt. Third, the missing piece — an MP4 export — got solved by community tools that capture the Claude Design share URL frame-by-frame.

None of these three pieces alone is enough. NotebookLM Cinematic is locked behind the Google AI Ultra plan ($249.99/month) and produces the entire video in one shot — great for explainers, no fine-grained creative control. Claude Design produces stunning custom animations but does not provide an embed code, an oEmbed endpoint, or a documented iframe path — and crucially, no native video file. The export tools fix the third gap. Together, the three layers form a pipeline that gives you NotebookLM's grounding accuracy, Claude Design's visual flexibility, and a clean MP4 you can upload anywhere.

What changed (and what didn't)

The 3-phase pipeline

End-to-end process for a 60-second grounded explainer. Total time: 35–60 minutes from sources to final MP4.

Phase 1 — Ground your video in NotebookLM (15–25 min)

Open notebooklm.google.com. Create a new notebook. Upload 3–15 sources: PDFs, research papers, Google Docs, web URLs, transcripts. Anchor a single topic per notebook — "GLP-1 weight loss outcomes," not "health." Set custom instructions in the notebook menu → Instructions: tell NotebookLM your audience, your angle, and that you're producing a 60-second explainer video.

Run two queries before you write any video brief. First, generate an Audio Overview — the AI podcast format. It will identify the strongest narrative arc through your sources, which is exactly what a 60-second video needs. Second, ask for a structured briefing: "Identify the 3 strongest grounded claims, the single most counterintuitive finding, and the 90-second narrative arc that connects them. Output as a beat sheet." The Audio Overview gives you the voiceover spine; the briefing gives you the on-screen text.

Phase 2 — Generate the animation in Claude Design (15–25 min)

Open claude.ai/design (Pro, Max, Team, or Enterprise). Paste the NotebookLM beat sheet and the narration script as context. Use the featured prompt above to generate a structured brief, then paste that brief as your Claude Design instructions. Ask Claude to build the animation as a single self-contained HTML artifact with CSS animations only — no external scripts, no audio tags. This matters for export: the simpler the artifact, the cleaner the frame capture.

Iterate visually. Claude Design renders the artifact live in the panel beside the chat. Refine timing, color, typography, easing curves through follow-up messages: "the headline beat is too fast — slow it to 1.8s and add a typewriter reveal," "the gold accent should be #9a7a2e not yellow," "make the data callout pulse twice on entry then settle." When the artifact plays correctly start-to-finish in the preview pane, you're ready to export. Click Share to generate a public URL with an auth token — you'll need this for Method B and C.

Phase 3 — Export to MP4 (5–10 min)

Three methods, detailed in the next section. Pick based on which subscriptions you have, how much creative control you want, and whether you can tolerate a third-party tool in the loop.

The 3 export methods compared

Method A — NotebookLM Cinematic Video Overview (native, Ultra only)

If you have a Google AI Ultra subscription, you can generate up to 20 Cinematic Video Overviews per day. Open your notebook, click into the Studio panel, select Video. Generate without a prompt for one-click output, or add direction like "three-minute explainer for a non-technical audience, focus on the contradiction in source 4." The whole pipeline runs server-side — generation takes a few minutes. The result is a polished animated video grounded in your sources, with NotebookLM's narration voice. Limitations: English-only at launch, restricted to users 18+, no fine-grained editing after generation, no creative direction over visual style. This is the right method for executive briefings, lecture summaries, and any use case where speed matters more than aesthetics.

Method B — Claude Design share URL → frame capture (recommended)

This is the path most readers will use. After generating your animation in Claude Design, click Share to get a public URL with an embedded auth token. Then send that URL to a service that opens it in a headless browser and captures every frame. The community-built tool claude2video.com is the most reliable option as of May 2026 — free, no signup, no watermark, exports MP4 at H.264, 30fps, in the animation's native dimensions. The pipeline runs server-side: paste URL, get MP4 back, usually under a minute for a 60-second animation.

Safety check. The share URL contains an auth token. Treat it as you would any link you'd send to a colleague — anyone with the URL can open the animation in a browser without logging in. The operator's published threat model states the URL is used once to render and source content is not stored. For sensitive client work or pre-launch product content, this matters. If you can't accept third-party rendering, use Method C instead.

An alternative tool, claudevideoexport.com, accepts both share URLs and uploaded ZIP exports. Useful as a backup if claude2video is rate-limited or down.

Method C — ZIP download → Remotion or FFmpeg conversion (developer path)

Claude Design lets you export the animation as standalone HTML/ZIP. If you're comfortable with a terminal, you can convert that to MP4 yourself: open the HTML in a headless Chromium instance via Remotion or Puppeteer, capture frames, encode with FFmpeg. This gives you full control over resolution, frame rate, codec, and color space. The tradeoff is setup time — expect 15–30 minutes the first time, ~5 minutes once your script is dialed in. Hand the ZIP to Claude Code with a prompt like "convert this Claude Design HTML artifact to a 1920x1080 60fps MP4 using Puppeteer + FFmpeg, output to ./out.mp4" and Claude Code will write the conversion script for you.

(Fallback) Screen recording

OBS Studio, Loom, or your OS's built-in screen capture (Mac: Cmd+Shift+5, Windows: Win+G) all work. The tradeoff is real: screen recording drifts and makes interactions look laggy — bar races, fast UI transitions, and gradient backgrounds suffer most from screen recording artifacts. Use this only when other methods aren't available, and aim for 60fps native resolution.

The 30 premium prompts — six categories, five prompts each

The free prompt above (Grounded Video Architect) is the entry point — one prompt that walks you from sources to a Claude Design brief. The premium library extends that into the full production pipeline. Six categories below; the gate at the bottom unlocks all 30 prompts plus the Notion command center.
