You have a landing page. You want a 15-second promo for X, LinkedIn, a Shorts feed, or the top of an email. The usual options are bad: a raw screen recording looks flat and amateur, and rebuilding the page as a motion-graphics clip in After Effects takes hours you don’t have.

There’s a faster path: let a tool read the page and animate it for you. This guide explains how website-to-video works, then walks a real example end to end — including the exact brief data the AI extracts.

Screen recording vs. motion graphics

Two ways to make a video “of” a website:

  • Screen recording — you scroll the live page and capture it. Quick, but it looks like what it is: a cursor moving over a webpage. No motion design, no hierarchy, no brand framing.
  • Motion graphics — the page’s content (headline, tagline, key points, screenshots) is re-composed as an animated clip: kinetic typography, the screenshots floating in as device mockups, everything tinted to the brand. This is the “explainer” look you see in good product launches.

The second looks far more polished — and it’s the one you can now automate, because the inputs (copy + screenshots + brand color) can all be read off the page.

The pipeline, in plain terms

A website-to-video tool does four things, in order:

  1. Capture — open the URL in a headless browser and screenshot the hero plus a couple of sections.
  2. Read the brand — run those screenshots through a vision model to extract the copy and the accent color.
  3. Design — have an AI write an animated composition that arranges that copy over the screenshots.
  4. Render — play the animation frame by frame and encode it to an mp4.

In ViralMint all four run on your own machine except the two AI calls, which route through its cloud (so there are no API keys to manage). Steps 1 and 4 use the same bundled Chromium and FFmpeg that power its downloader — nothing extra to install.

A worked example

Take a typical SaaS landing page with the hero headline “Ship your side project this weekend,” a sub-headline about shipping faster, and three feature blurbs. After the capture + vision step, the extracted brief looks like this:

{
  "headline": "Ship your side project this weekend",
  "tagline": "From idea to deployed in 48 hours — no boilerplate",
  "key_points": [
    "Auth, payments and a database, preconfigured",
    "Deploy to the edge with one command",
    "Generated TypeScript types end to end"
  ],
  "accent": "#6366F1"
}

That JSON is the entire creative brief. Notice what it is and isn’t: it’s the page’s own words and its own color (#6366F1, an indigo), not invented marketing copy. The key_points array is clamped to three so the video stays tight; if the vision read can’t find a clean accent color it falls back to a neutral default rather than guessing.

From that brief, the AI writes a composition — real HTML/CSS/JS with a GSAP timeline — that:

  • animates the headline in as kinetic typography (word-by-word, in the indigo accent),
  • slides the three key points in as a stack,
  • floats the captured hero screenshot in as a laptop-style mockup, and
  • holds on a closing card with the tagline.

Because the output is web code rather than a baked template, you can open it in the studio afterward and change the timing, swap a screenshot, or rewrite a line — then export again.

How to do it in 5 steps

  1. Pick the URL and aspect ratio. Paste the public link; choose 16:9 (YouTube), 9:16 (Shorts/Reels/TikTok) or 1:1 (feed).
  2. Capture. A local headless browser screenshots the hero and two sections. It’s a public capture — no login or site ownership needed.
  3. Read the brand. A vision model extracts the headline, tagline, up to three key points and the accent color (the brief above).
  4. Generate. AI writes the motion-graphics composition laying that copy over the screenshots, in the brand color.
  5. Render and export. A headless browser plays the timeline frame by frame; FFmpeg encodes the mp4 (~15–25s). Download it, or edit the composition in the studio and re-export.

What it costs, and where it fits

Per video, this runs about 9¢ in ViralMint — the AI compose step plus the local render, billed from prepaid credits, no subscription and no watermark. The capture and render are local, so there’s no per-minute cloud charge.

Where it fits: it’s purpose-built for promoting your own landing page, but it works on any public URL you want to summarize as a short clip. If you want to hand-craft the animation instead of auto-generating it from a URL, the same engine is available directly as Motion Graphics — describe a scene and AI writes the composition. And if you’d rather build from real footage than animated text, Smart Video assembles stock clips with an AI script, voiceover and captions.

Website-to-video won’t replace a hand-designed launch film. But for the dozens of short promos a product actually needs — one per feature, one per channel, one per update — turning the page itself into the video is the difference between shipping them and not.
