How to write AI motion graphics prompts: a practical guide with examples

Kario Team · October 1, 2026 · 4 min read

Give an AI motion graphics tool a topic, and it will make a video about the topic. Give it a brief, and it will make your video. Most disappointing first passes come from the first kind of prompt.

This guide covers what a strong motion graphics prompt contains, with before-and-after examples you can adapt.

The anatomy of a strong prompt

Goal
What the viewer should do or remember
Audience
Who's watching, and where
Content
The exact words, numbers and assets
Structure
The beats, in order
Style
Look, type and motion feel
Format
Length, aspect ratio, sound

You don't need all six every time. But each one you leave out is a decision you're letting the AI make for you.

1. Goal: say what the video is for

"A video about our new feature" has no goal. "Get existing customers to try bulk export this week" does, and it changes the video: it should show the feature working, assume the viewer knows the product, and end on where to find it.

2. Audience: name who's watching, and where

Developers on X, buyers on LinkedIn and shoppers on Reels need different pacing, vocabulary and framing. Say it in a line: "Product managers at mid-size SaaS companies, watching in the LinkedIn feed with the sound off."

"Sound off" alone changes the video: every important line needs to be on screen.

3. Content: give the exact words and assets

AI fills gaps with plausible filler. Don't leave gaps where accuracy matters:

  • Headlines you've already written, in quotes.
  • Numbers, exact: prices, stats, dates.
  • Your logo, screenshots and product URL. Attach them instead of describing them. Kario reads a pasted URL for your page's facts and wording.

4. Structure: list the beats

A beat is one idea on screen. Listing them in order is the single most effective thing you can add to a prompt:

Hook: "Exports used to take an afternoon." → The feature: select 200 rows, one click. → Proof: "12 seconds" counts up. → CTA: "Bulk export is live in Settings."

Four beats in 15 seconds is plenty. If you have eight, you have two videos.

5. Style: describe the look in concrete terms

"Modern and clean" describes almost every video. Give references Kario can act on:

  • Palette: "Black background, white type, one accent in #3B82F6."
  • Type: "Big, tight, bold sans headlines. Short lines."
  • Motion feel: "Snappy, confident moves that settle quickly" vs "slow, calm fades and drifts."
  • What to avoid: "No stock photos. No gradients."

If you're unsure, let Kario propose directions and pick one. Choosing between three concrete options is easier than inventing one.

6. Format: length, ratio and sound

"15 seconds, 9:16, with music, no voiceover" settles four decisions in one line. For a narrated video, say the language and the voice you want, and ask to approve the script before anything is animated.

Before and after

Before: Make a video for our project management app launch.

After: A 20-second launch video for Tasklane, 16:9, for team leads at startups, sound on with music. Goal: get signups on launch day. Beats: "Your standup, minus the meeting." → the board updating itself as teammates check in (use the attached screenshots) → "Saves 3 hours a week per team" → logo and "tasklane.com". Style: off-white background, black type, our green (#16A34A) as the only accent, crisp UI movement, no stock imagery.

The second prompt is longer, but every line in it is a decision you'd otherwise spend a revision round on.

Giving notes on the first pass

The prompt gets you a first pass. Notes get you the finished video. Good notes are:

  • Located: "In the proof scene…" rather than "somewhere in the middle…"
  • Specific: "Hold '3 hours' for a full second" rather than "make it more impactful."
  • One problem per note: easier to apply, easier to check.

And remember that you don't have to prompt your way to every fix. Every layer in a Kario project is editable, so for a typo or a nudge, select the layer and change it directly. Use chat for changes that touch many layers at once, like pacing, colour or a new scene.
