The Claude 3D Skill: 3D story videos from one prompt.

The Claude 3D Skill (our 3D Story Skill) teaches Claude Code how to build a complete 3D story video in code: the world, the characters, one continuous camera, captions on every word, sound on every action and a finished MP4. You write the story; Claude builds and renders it on your own computer.

What the Claude 3D Skill makes

Vertical Shorts (9:16) and wide YouTube videos (16:9), usually 30 seconds to 5 minutes long. Typical results:

• A town, a room, a shop or a whole street built in 3D, with real light, shadows and depth of field.
• Expressive 2D characters standing in that 3D world, acting out each line of your story.
• One floating camera that never cuts, flying through windows and screens into the next place.
• Word-synced captions, a mastered voice and a sound plan (footsteps, clicks, crowds, music) mixed to −14 LUFS.

See finished examples in the prompt library; every sample there was built this way.

Why use a skill instead of an AI video generator?

Clip generators give you a few seconds at a time, and characters, signs and text change from clip to clip. A Claude skill renders the whole video from code, so:

• Characters stay identical in every shot, because they are drawn by the same code.
• Long continuous shots are possible: 10, 20, 60 seconds without a cut.
• Every word is timed: the picture follows the voiceover word by word.
• No credits per clip: you render on your own machine as often as you like.
• Readable text: signs, labels, screens and numbers are exact.

What you need

• Claude Code on a paid Claude plan.
• Node.js 20 or newer, Google Chrome, ffmpeg and Python 3 (with numpy and Pillow).
• A voiceover: your own recording or any text-to-speech tool.
• The skill itself, included in every membership.

How to make your first 3D video with Claude, step by step

1. Download the skill from your account and unzip it into your Claude skills folder (the guide inside the ZIP shows the exact path for macOS and Windows).
2. Pick a prompt from the library or write your own story in a few lines: who, where, what happens, and the twist.
3. Record or generate the voiceover. Clean speech at a natural pace (around 150 words a minute) works best.
4. Open Claude Code in an empty folder, paste the prompt and attach the voice file. Claude plans the scenes, builds the world and times the camera to your words.
5. Check the test frames Claude shows you, ask for changes in plain words (“closer on her face”, “make the street busier”).
6. Render. A one-minute Short at 2K takes about 5–10 minutes on a recent Mac. You get an MP4 ready to upload.

Tips that make the videos look like short films

• Keep the camera slow: a calm drift reads as cinema, a fast spin reads as a glitch.
• Give every named thing its picture in the same second it is spoken.
• One colour mood per video (warm amber, cool blue night) beats a rainbow.
• Open on a face or a clear object and a strong first line; the first two seconds decide the view.
