Logo Reveal Animation With AI: Prompts, Code and Export

A logo reveal animation is the easiest piece of motion design to get right with AI. It's short, it has one subject, and you know exactly what the last frame should look like: your logo, sitting still. A 30-second launch video needs a story, pacing and readable captions. A reveal needs none of that.

Here's the prompt that works, a better one, five kinds of reveal, and an SVG logo animation in pure CSS you can paste into a page today.

Why logo animation with AI works so well

  • It's short. Three to six seconds, so there's little room for the pacing to go wrong, and reruns are cheap.
  • There's one subject. No scenes, no captions, no UI to rebuild. Just the mark and maybe a wordmark.
  • The end state is fixed. The final frame has to match your logo file. That gives you, and the model, a check that isn't a matter of taste: if the last frame doesn't match logo.svg, it's wrong.

That last point matters most. AI motion usually fails on taste, which is hard to pin down. With a reveal, half of good is just correct.

The one-liner that works

Tony Dinh (@tdinh_me) posted this prompt for Claude Opus 5.5, with the advice to attach your own product logo when you run it:

Create an impressive motion design video of a slow-reveal transition that assembles and eventually reveals the TypingMind logo.

It's one sentence, and it does more than most prompts in our directory. "Slow-reveal" sets the pace. "Assembles" picks a technique. "Eventually reveals the logo" gives it an ending. Attaching the real logo means the model works from your actual shapes instead of guessing at them from a name.

Swap in your brand and you'll get something decent. What you won't control is everything else: the length, the background, what the pieces assemble from, and whether the model adds a particle burst and a lens flare on the way. That's where a longer prompt earns its keep.

A better logo reveal prompt

This one is ours. Fill in the brackets.

Make a 4-second logo reveal animation for [brand], 1920x1080, 60fps.

The logo is logo.svg in this folder. [Only have a PNG? Trace logo.png to a clean SVG first, keep the shapes and colors exact, and show it to me before you animate anything.]

Build the reveal out of the logo's own geometry: draw its strokes, assemble its real shapes, or wipe it in. Nothing appears on screen that isn't part of the logo.

Timing: the reveal takes about 3 seconds. Then the finished logo holds, completely still, for at least 1 second. Ease out into the final position, with a small overshoot at most.

Background: flat [#0E0E0E]. The logo's colors stay exactly as they are in the file.

Sound: one hit on the moment the logo resolves, nothing else. [Delete this line if there's no audio.]

Avoid: particles converging, lens flares, glows, light sweeps, camera shake, 3D spins.

Build: one HTML file with every frame computed from seek(t).
When it's done, render frames at 0.5s, 1.5s, 3s and 3.9s, look at them, compare the last one with logo.svg, and fix anything that doesn't match before you show me.

Why each part is there:

  • The SVG. Claude can draw a vector's paths, move its shapes and land on the exact final geometry. A PNG is a flat picture, so the most it can do is fade, scale or mask it. If you only have a PNG, have Claude trace it first. @aschapmann's Remotion launch prompt does exactly this, tracing the logo to SVG "so it stays sharp and can be animated", and ends the video on "a memorable animated logo reveal with the tagline and URL." Check the traced file against the original before you animate anything.
  • The logo's own geometry. This is the most important line. A reveal built from the logo's real strokes and shapes looks like it belongs to the brand. A reveal built from generic effects looks like a template with your logo pasted on the end.
  • About 4 seconds, with a 1-second hold. Models tend to rush the ending. A held final frame gives the eye time to land on the logo, and gives you a clean frame to cut on.
  • A background color. Otherwise the model picks one, and it probably isn't yours. If the reveal has to sit over footage, ask for a transparent background instead.
  • One sound hit. If there's audio, one sound on the resolve does more than a soundtrack. Leave it out if the reveal will play muted.
  • The banned list. Converging particles, lens flares and glows are what the model reaches for when nobody stops it. Name them and they mostly stay away.
  • Render and check. Claude Code can render frames and look at them. Tell it to, and tell it to compare the last one with the logo file.

Five kinds of logo reveal

Pick one before you prompt and name it. "Reveal" on its own leaves the choice to the model.

  1. Stroke draw-on. The outline draws itself, then the fill comes in. Best for line-based marks, monograms and script logos, and the easiest one to do in plain CSS.
  2. Assemble from parts. The logo's separate shapes slide, rotate or drop into place. Use it when your mark is built from distinct pieces, like a grid of squares or interlocking letters. It's what Tony Dinh's prompt asks for.
  3. Mask or wipe. An edge or shape sweeps across and uncovers the logo. It works with any logo, even a flat PNG, so it's the safe choice for complicated marks and long wordmarks.
  4. Morph from a simple shape. A dot, circle or square turns into the mark. It needs a simple silhouette. Detailed outlines turn to mush halfway through.
  5. Particle converge. Dots fly in and settle into the logo. It's the most overused reveal there is. Only use it if particles actually mean something for your brand.

An SVG logo animation in pure CSS

You don't need AI or a video file for the web version. This is a stroke draw-on, then a fill, then a wordmark wipe, in plain HTML and CSS with no JavaScript. The mark is a ring and a triangle; swap in your own paths. Paste the HTML into the body of a blank page and the CSS into a style tag.

<div class="logo-reveal">
  <svg class="mark" viewBox="0 0 120 120" width="96" height="96" aria-hidden="true">
    <path class="ring" pathLength="1"
      d="M60 10 A50 50 0 1 1 60 110 A50 50 0 1 1 60 10" />
    <path class="tri" pathLength="1"
      d="M60 32 L84 76 L36 76 Z" />
  </svg>
  <span class="wordmark">Acme</span>
</div>
:root {
  --ink: #141414;
  --paper: #f5f3ee;
  --ease-draw: cubic-bezier(0.65, 0, 0.35, 1);
  --ease-out: cubic-bezier(0.16, 1, 0.3, 1);
}

body {
  margin: 0;
  min-height: 100vh;
  display: grid;
  place-items: center;
  background: var(--paper);
}

.logo-reveal {
  display: flex;
  align-items: center;
  gap: 20px;
  color: var(--ink);
}

/* Each path is one dash as long as itself, pushed fully out of view. */
.mark path {
  fill: none;
  stroke: currentColor;
  stroke-width: 6;
  stroke-linejoin: round;
  stroke-dasharray: 1;
  stroke-dashoffset: 1;
}

.mark .ring {
  animation: draw 1.1s var(--ease-draw) forwards;
}

.mark .tri {
  fill: currentColor;
  fill-opacity: 0;
  animation:
    draw 0.9s var(--ease-draw) 0.5s forwards,
    fill-in 0.5s var(--ease-out) 1.4s forwards;
}

.wordmark {
  font: 700 56px/1 system-ui, sans-serif;
  letter-spacing: -0.03em;
  clip-path: inset(0 100% 0 0);
  animation: wipe 0.8s var(--ease-out) 1.6s forwards;
}

@keyframes draw {
  to { stroke-dashoffset: 0; }
}

@keyframes fill-in {
  to { fill-opacity: 1; }
}

@keyframes wipe {
  to { clip-path: inset(0 0 0 0); }
}

/* No motion wanted: show the finished logo. */
@media (prefers-reduced-motion: reduce) {
  .mark .ring,
  .mark .tri,
  .wordmark {
    animation: none;
  }
  .mark path { stroke-dashoffset: 0; }
  .mark .tri { fill-opacity: 1; }
  .wordmark { clip-path: none; }
}

How it works:

  • pathLength="1" does the hard part. It tells the browser to treat the path as exactly one unit long, whatever its real length. So stroke-dasharray: 1 makes a single dash as long as the whole path, and stroke-dashoffset: 1 pushes that dash completely out of view. Animate the offset to 0 and the line draws itself. Without it, you'd measure every path with JavaScript and hard-code the numbers, and they'd break the moment you edited a shape. With it, the same CSS works on any path at any size.
  • The delays are the sequence. The ring starts at 0, the triangle at 0.5s, its fill at 1.4s and the wordmark at 1.6s. Overlapping them a little makes it read as one move instead of four.
  • The wordmark wipe is a clip. clip-path: inset(0 100% 0 0) cuts the text away from the right edge all the way across. Animating it to inset(0 0 0 0) uncovers it left to right. It's real text the whole time, so screen readers and search engines can still read it.
  • The easing is custom. The strokes ease in and out so lines start and finish gently. The fill and wipe use a strong ease-out so they arrive fast and settle.
  • Reduced motion gets the final frame. If someone has asked their system for less motion, they see the finished logo straight away.

The whole thing runs about 2.4 seconds, which is right for a page. For a video intro, stretch it toward 4 seconds and add the hold.

Exporting a logo reveal

If it's going on a website, keep it as SVG and CSS. It's a few lines of markup, sharp at any size, and it respects reduced motion. A video file is far heavier, goes soft when you scale it up, and plays the same for everyone.

If you need an actual video, for a YouTube intro, a slide deck or the end of a launch video, render it frame by frame instead of screen-recording it. The full setup is in editing and exporting AI motion to MP4. If Claude built it in Remotion, rendering is one command:

npx remotion render src/index.ts LogoReveal out/logo-reveal.mp4

Use your own composition ID in place of LogoReveal. If the logo has to sit over footage in an editor, you need a format with transparency, and Remotion's docs cover how to render one.

More to work from

For CSS you can drop straight into a page, Keyframe Animations has fade, slide and zoom entrances, and Text Animations has wipe, mask and stroke-draw reveals that work well on a wordmark or tagline. For AI prompts, open the Motion Prompts directory and filter by Logo reveal.
