The Motion Designer Showreel Prompt, Explained (and How to Beat It)

If you were on X in late September 2026, you saw this prompt. Maybe forty times.

make a dynamic 15-second motion graphics video that shows what an incredible motion designer you are, like it's your showreel for a résumé. go all out.

Pasted into Claude Opus 5.5, it produces a slick 15-second reel of kinetic type, morphing shapes, particles and self-assembling UI. People posted the results with captions like "this is all code, zero After Effects," and the posts did numbers. We tracked 41 different creators who posted runs of it. It's the most-run prompt in our Motion Prompts directory by a mile.

Where it came from

The earliest post with this exact prompt that we found is from @shneural on September 24, comparing Opus 5.5 against another model with the same prompt. The best-known run came about eleven hours later from @stephanlivera, on max effort, and passed two million views. A lot of people credit @stephanlivera for the prompt. If someone posted it before either of them, we haven't seen it.

Why it works

It's a well-built prompt, whether or not anyone designed it that way.

  • It gives the model a role and an audience. "Showreel for a résumé" tells it what a showreel is for: variety, range, fast cuts, best work only.
  • It sets a hard length. Fifteen seconds forces density.
  • It has no subject. Nothing to get wrong, no brand to match, no facts to check. The model shows off what it's best at.
  • "Go all out" is permission to spend effort. Paired with max effort, the model builds more.

It's also reliable. One skeptical developer, @codestackr, posted that the "one prompt" claims had to be lies, tried it, and said the result came from the first take.

Where it falls short

The video is about the model. That's fine for a demo and useless for almost anything else. The common next step was to swap in a product name: "a showreel for Distilbook", "for our referral program", "for my agency." The output is a reel of techniques with a logo dropped in at the end. It doesn't explain the product. It shows off the model with your name attached.

It also converges. Of the 41 runs we catalogued, 31 lean on kinetic type, 26 on geometric shapes and 14 on particles. Run it enough and you start recognizing the moves before they happen.

The variants people tried

Three rewrites that beat it

These are ours. Each keeps what works about the original and fixes one weakness.

1. The constrained showreel

For a reel that doesn't look like everyone else's. Constraints are where style comes from.

Make a 15-second motion graphics showreel that proves you're a great motion designer.

Rules: black, white and one accent (#FF4F00). One typeface. No particles, no glows, no gradients, no 3D camera spins.
Every transition is a match cut: the last shape of one idea becomes the first shape of the next.
Show five distinct techniques and hold each long enough to register.
Build it as one HTML file, 1920x1080, 60fps, with every frame computed from seek(t). Render a frame per technique and check them before you show me.

2. The product reel

For when you actually need to sell something. It turns the brief from "show what you can do" into "show what this does."

Make a 20-second motion graphics video for [product] that shows what it does, not what you can do.

Read [landing page URL or the screenshots in this folder] first.
Pick the three features a new user would care about most. One scene each, showing the real UI doing the thing, with one short caption.
Open on the problem in one line. End on the logo, the tagline and the URL, held for two seconds.
Same style rules as our brand: [colors, font]. Avoid particles and glows.

3. The explainer

For teaching instead of showing off. Some of the best pieces in the directory are explainers, like @emollick's recursion video and how the first-down line works on TV.

Make a 30-second motion graphics video that explains [concept] to someone who has never heard of it.

One idea per scene, five scenes at most. Use simple shapes and diagrams, not decoration.
Every line of text stays on screen long enough to read twice.
End with the one sentence a viewer should remember.

The takeaway

The showreel prompt proved that one sentence and a high effort setting can produce real motion design. It didn't prove that one sentence is enough for your video. Use the original to see what the model can do. Then write a prompt about your thing.

Every run we found is linked from the showreel entry, credited to its creator, so you can compare forty-one takes on the same sentence.
