Designed motion, not stock filler
Some messages — launches, stats, brand moments — look wrong over stock footage. This is the mode for genuinely designed animation: kinetic typography, animated data cards, lower-thirds, device mockups.
Kinetic typography and stat cards, from a one-line brief
For launch teasers, stat reels and brand animations, footage is the wrong tool. Claude sends your creative brief to ViralMint's Motion Graphics studio, which authors a real animated composition — kinetic type, data cards, product mockups — and renders it locally.
You type
Launch teaser for my app — confident, Apple-keynote energy, end on the URL. 16:9.
…and Claude drives the whole pipeline below on your machine.
Why this beats a blank script box
Compose for a nickel, render for free
Authoring a composition is $0.05 and refining is conversational; the actual rendering runs on your own machine. Iterating on a launch teaser doesn't meter per second like AI video models do.
A real studio underneath
Compositions are HTML/CSS/JS in an embedded HyperFrames studio (Apache-2.0) — fine-tune visually in the app, keep every archived version, or hand-author compositions yourself and submit them for just the render fee.
How Claude creates a motion-graphics video
-
Give the creative direction
Message, vibe, optional headline, accent color, aspect. motion_compose sends the brief to ViralMint's cloud model, which writes a real HyperFrames composition — you write zero code.
-
Refine in plain language
'Make the headline bigger', 'darker palette', 'slower, more dramatic pacing' — each instruction edits the live composition in place, with every previous version archived.
-
Render locally, import to Library
The composition renders to MP4 on your machine (Chrome + FFmpeg — no cloud render minutes), and motion_sync_renders files it into your Library like any other video.
-
Shortcut: website → promo
Have a URL instead of a brief? website_to_video screenshots the site, reads its brand with a vision pass, and authors a promo with the site's screens as floating mockups — about $0.23 end to end.

-
Install ViralMint
Download the free, open-source desktop app (macOS / Windows / Linux) and open it. It bundles the whole pipeline — yt-dlp, Whisper, FFmpeg — and the MCP server.
-
Open the in-app MCP page
It shows your loopback endpoint and a bearer token, with a ready-to-paste Claude Code command and a JSON config snippet for Cursor / Claude Desktop.
-
Add the server to your agent
Paste the command. Your client loads ViralMint's tools, the built-in workflow recipes (this skill is one) and read-only resources like your balance and recent videos.
-
Ask for the outcome
Type the prompt above. Claude runs the recipe end-to-end against the local app and hands you the finished mp4 — no clicking through the UI.

FAQ
Frequently asked
What kinds of videos is motion graphics right for?
Launch teasers, product and app showcases, animated stat/data reels, quote and hook cards, lower-thirds and brand idents — anything where the design IS the content and real footage would look generic.
Do I need to know After Effects or write code?
No. You give creative direction in plain language; ViralMint's cloud model writes the composition (kinetic timeline included) and Claude iterates it from your feedback. If you DO know HyperFrames, you can author compositions yourself and pay only the render fee.
What does it cost?
Composing is $0.20 per composition and importing a render is $0.03 — the render itself runs locally, so there are no per-second cloud charges. The website-to-promo shortcut lands around $0.23 total.
Can it make a promo video of my website automatically?
Yes — website_to_video takes a URL, screenshots it locally, reads the brand (headline, value prop, accent color) with a vision pass, and renders a motion promo featuring the site's own screens. One call, straight to your Library.
