Free · motion skill for Claude Code

Your motion skill is ready.

Install the skill with one prompt, then make your first video with one of the prompts below.

SKILL.md · cinematic-motion

Your free skill: cinematic-motion

  • Turns a plain description into a motion video made in code: Remotion, React and three.js, with 3D camera moves, kinetic type, glass UI and light.
  • Claude plans the video, builds it, checks it frame by frame and renders an MP4 in 9:16 and/or 16:9.
  • You talk in plain words: it never asks you to run a command or edit a file.

Paste it into Claude Code: it downloads the skill, checks it and installs it by itself.

The skill is open on GitHub
install prompt
Set up the cinematic-motion skill in this folder, then make a video with me using it.

SETUP
Work only inside the current folder, and never delete or overwrite files that are already here. First check that this computer has Node.js 20 or newer. If it is missing or older, stop and tell me to install Node.js LTS from nodejs.org with its normal installer, then wait for me.
Download these three files into a new folder named cinematic-motion-download here, each saved byte for byte, not through a tool that summarizes or rewrites pages. If that folder already exists or is a symbolic link, stop and ask me.

Check the SHA-256 of each one: SKILL.md fc62803f4b23fbf5546139e90ef89862bb3860a9c2b7a3fbc8fc525a9af7bf22, package.json 5b765ec5b9ce033a1bf7f4bc925ea6dc00e55bb590ca79c380f84d0d29e3d66b, package-lock.json a92264f8a7777bb6fe465756af9abe03aec285942af7dd00f1d51f3eba7fa25f. If one doesn't match, delete the cinematic-motion-download folder you just made, don't use any of the files, stop and tell me.
Only when all three match: if .claude/skills/cinematic-motion already exists, or any part of that path is a symbolic link, stop and ask me. Otherwise create the folder .claude/skills if it is missing and move the whole cinematic-motion-download folder there in one rename, so it becomes .claude/skills/cinematic-motion.
Install packages only from these pinned files, as the skill describes: npm ci --ignore-scripts from the lock file, which pins every npm package and its hash, the fonts included, inside a new project folder the skill creates here. Don't add, update or remove a package. The only other download is the one the skill names: the browser Remotion renders with, which the skill pins by its SHA-256 too and checks before it is used. Never use sudo. Before each install or download, tell me in one line what it is and wait for my OK. Don't ask me to run commands.

THEN
Read .claude/skills/cinematic-motion/SKILL.md in full and follow it for everything below. Then ask me which video I want: I'll paste one of the prompts from the skill page, or describe my own idea. For the prompt I paste, ask me in one short message only for what is in [brackets] and for any logo, colours, references, music or sound effects I have, then use that prompt as the brief of the skill's first step. Use only the packages the setup installed. Sound comes only from files I give you; without them, keep the video silent and give me a second by second list of where sounds would go. Show me the storyboard before you build. When the video is done, tell me where the MP4 is and how to ask for changes.

I'm not a programmer: do everything you can yourself.

Then make your first video

When Claude asks which video you want, paste one of these prompts and fill in what is in [brackets].

Sky Glass

9:16 · about 30 s · 60 fps

Sunlit 3D clouds, frosted glass panels and a laptop floating in the sky.

Make this video with the cinematic-motion skill. A vertical 9:16 reel, 1080x1920, 60 fps, about 30 seconds, about [my product or topic]. The camera is already flying through a bright sky at frame 0: sunlit 3D clouds, golden light, white and lavender tones, never a flat gradient. One dark contrast beat: black with a glowing horizon and huge white type. Every UI piece is frosted glass: blur, a 1 px inner highlight, a soft shadow and a light sweep across the glass on key beats. Real 3D objects lit by the same sun: a laptop floating in the clouds, a paper card turning in perspective, video cards fanned out in depth. Type: a heavy sans for the hero word and an italic serif for one accent word per line. Short lines, one idea per shot, a new visual on every line: [my lines]. Nothing pops in: every element flies in along the camera path, unfolds from another object or is revealed by a mask. Motion blur only on fast moves. End on a glass comment bubble with [my call to action].

Night Amber

16:9 · about 28 s · 60 fps

A dark, warm launch film: a phone, a 3D city, a box that opens with light.

Make this video with the cinematic-motion skill. A horizontal 16:9 film, 1920x1080, 60 fps, about 28 seconds, a launch film for [my product]. A dark warm world: black to deep brown, terracotta and amber light, dust in the air, the camera always moving. Every hero object is a lit 3D mesh with real thickness, not a flat picture. Shots: 1) a glowing swoosh draws itself and the wordmark [my product name] rises letter by letter above it; 2) a phone rises into frame with an amber rim light while thick video cards orbit it, passing in front of it and behind it; 3) close on the phone: a reference card drops into the prompt box, one sentence types in, the send button is pressed in an extreme tilted close-up, then the screen fills with shots and a progress bar; 4) a dark 3D city of blocks, seen from above, then low, where an amber route draws from start to finish and shot tiles rise along it; 5) the product as a real box on varnished dark wood, a light trail draws the logo on it, the lid opens and warm light spills out; 6) big type with one italic serif accent word in amber and a light sheen: [my line]; 7) the logo again, then a thick glass comment slab with [my call to action]. Transitions by light: a streak across black, an amber defocus, a bloom out of the box.
