- Reported result
- The artist shares a video and reports a finished one-minute film drawn by code. A short rendered section and plain-language feedback preceded the full version; the author says requested visual corrections appeared in the next revision.
- Human involvement
- The artist supplied drawings and assets, reviewed a short finished section and directed visual revisions. The After Effects setup remained editable; the source does not say every frame or script received a human audit.

How the agent did it
- The artist supplies personal sketches and studio assets, using ChatGPT to create sketch versions of their drawings.
- Claude Code builds a time-addressable web renderer and scripts frame capture, motion blur and video encoding.
- The artist reviews a finished 20-second stretch and requests English text, glowing dog outlines and removal of an unwanted logo line.
A studio artist posting as /u/Arctic-Hare-studio describes turning personal drawings into a one-minute vertical film with Claude Code. A blue pen line carries the sequence through handwriting, sketches, dogs, a game character and a studio logo. The post includes a video link and detailed instructions for reproducing the rendering approach.
The inputs were not all untouched originals. The artist says they gave their own drawings to ChatGPT for sketch versions in a reference style. Claude Code then built the film as a web page that can draw a specified moment in time. Scripts capture frames in headless Chromium, combine nearby samples for motion blur and encode the result with ffmpeg. The author also describes an editable After Effects finishing setup built with a script. Suno supplied music, and the voice used MCP Higgsfield.
Human direction shaped the result. The artist recommends completing a 20-second section before rendering the whole minute. Their reported corrections included keeping text in English, replacing unsettling pencil versions of the dogs with glowing outlines and removing a line beside the logo. They say each change appeared in the next version.
This is supervised creative production, not a claim that one prompt made a finished film. The distinction from AI video generation applies to the code-rendered frames, not to every input asset. The linked film and reported revisions are the evidence of an outcome; this review did not independently render or inspect the media.

Frequently asked questions
Did the artist avoid all generative image tools?
No. The artist used ChatGPT to make sketch versions of their own drawings. The claim about avoiding an AI video generator concerns the film frames, which Claude Code rendered through code.
How much direction did the finished film need?
The artist reviewed a finished short section and gave specific visual corrections before the whole minute. The post describes iterative supervision, not a single unattended generation.

Remaining steps
- Claude revises the film and scripts an editable After Effects finishing setup; music and voice use separate tools.
About this account
Claude Code built the rendering and finishing scripts and revised visual details from the artist's feedback. The workflow renders frames from code rather than generating video with a video model.
