A writer made a full animated promo video with just four AI prompts

A writer at How-To Geek says he made a full animated promo video using Claude in about four rounds of prompts. He did it on the $20 Pro plan, not the pricier plans that include Anthropic's animation tool, Claude Motion. For a small business, it hints that a simple promo clip may be within reach without hiring an animator.

How it works

Claude does not film or generate realistic video. It writes a small program that draws the animation, runs it, and saves the result as an MP4 file. Because Claude can run code on its own, a regular chat can do this, even on the web version. Claude Motion, which launched in October, is only on Team and Enterprise plans, but it is not required.

The four-prompt method

The writer used Opus 5.5, a Claude model released September 22, 2026, at Medium effort. His first prompt is the big one. It describes the length, the style, the scenes and the mood. He says that single prompt does about 60% to 70% of the work.

Then come three or four smaller prompts for tweaks, such as slowing a scene, changing a color or swapping the style of the ending. With a few edits of his own, he had a usable video in about four rounds.

What it cannot do

• It will not produce real footage or realistic people.
• It will not add a voice-over.
• Longer animations use more of your usage limit.
• Early results can have flaws like overlapping text, odd limb movement, and objects drifting out of frame.

The writer saw those flaws in his first stickman videos for YouTube. Small follow-up prompts got them to a workable version. He has also added a tool called Remotion for more control, though he says the plain chat is enough for most short clips.

Why people are trying it

The trend took off after the Opus 5.5 release, according to the writer. Creators on X have shared 30-second product videos, explainers made from viral threads, and a launch film for a calendar app that does not exist. One creator, Charlie Hills, shared 16 motion graphics he made with Claude, along with his prompts and techniques.

What is not known

The available text does not show the finished How-To Geek promo, so how polished it looks is unclear. It also does not say how much of the Pro plan's usage limit a project like this takes. Anyone curious can start with a short clip and expect to refine it a few times.
