Claude Sonnet 5.5 renders a hand-painted music-video remake with roughly 15 subagents

A creator used Opus 5.5 for research and frames, then Sonnet 5.5 with roughly 15 subagents to render a hand-painted music-video remake. The workflow studied the original frame by frame to match choreography to the beat.

TL;DR

  • A 3:47 hand-painted Gangnam Style remake puts Clawd characters through beat-matched choreography; LLMJunky's film includes a reluctant horse and a view counter that overflows.
  • Opus 5.5 researched, planned and drew concept frames; Sonnet 5.5 built the animation. LLMJunky's production breakdown puts the combined job at about five hours on Max, with roughly two hours for Sonnet.
  • The production split the song into 14 chapters for parallel agents, following the frame-by-frame study and storyboard specified in LLMJunky's posted prompt.
  • The two versions look similar in LLMJunky's stacked comparison, but Sonnet inherited Opus's reference frames and code, as LLMJunky later clarified.

The published skill contains a beat-locked dance library and complete example projects without the songs. John Heibel's animation base supplies a Clawd rig with 31 acted emotions and a headless renderer.

CLAWDNAM STYLE

The remake follows a dance from a sandbox across a painted world. One horse refuses to join until the end, while a view counter reaches 2,147,483,647 and rolls over, according to the project's account of the film. It runs the full 3:47 song at 24 fps, or 5,460 frames.

The remix brief

The posted prompt asked for a hand-painted cartoon of the original video using Heibel's ClaudeAnimationBase and its animation guide. Its production constraints were specific:

  • Download the original and study it frame by frame before planning.
  • Recast the artist and dancers as distinct, consistent Clawd characters.
  • Preserve the recognizable choreography and put the big moves on the beat.
  • Give the video a funny new concept rather than copying shots exactly.
  • Play the whole song with continuous transitions.
  • Allow motion graphics and text, but omit lyrics.
  • Storyboard first, then assign work to subagents. The brief specified Opus 5.5 for all agents.
  • Give the production as much time as it needs.

Beat-locked chapters

The skill's production guide spells out the handoffs behind the parallel build:

  1. Study the source video's cast, sets, moves and shot structure.
  2. Measure the song's beat grid, bars, sections and dropouts. For this film, the project README reports 132 BPM and a millisecond-measured grid.
  3. Set the concept, cast sheets and sets before animating scenes.
  4. Give each song section to an agent with a shared guide and specified chapter boundaries. The finished film used 14 chapters and 14 subagents.
  5. Review character consistency, chapter seams, frames and final audio sync, then encode the master, 1080p file and preview.

The repo extends the base kit with costumes, poses, singing mouths and a beat-locked move library. LLMJunky's reply credits Heibel's work in the underlying repository.

Code-painted frames

Heibel's ClaudeAnimationBase draws with p5.js and p5.brush; its render.mjs generates contact sheets and MP4s using headless Chrome and ffmpeg. The skill adds scripts for downloading the reference, analyzing audio, checking synchronization and reviewing frames. A separate starks_arq clip demonstrates the code-made-video approach.

Opus plans, Sonnet animates

The actual run departed from the all-Opus brief. Opus did the research, writing, story and original concept frames, then Sonnet built from that work with roughly 15 subagents, LLMJunky reported. The project README counts 14 chapter-building agents; the creator's later estimate rounds the Sonnet team to about 15.

The comparison is a handoff test, not a clean model contest: Sonnet had Opus's frames and code as references, LLMJunky acknowledged.

Papercut's earlier pass

Before CLAWDNAM STYLE, LL‍MJunky posted Papercut, an Opus-planned and rendered reimagining of Linkin Park's video. Its conceit takes the title literally: the cartoon is painted on paper, with tears in the page, as LLMJunky explained.

The creator called that run a one-shot in a reply, estimated five to six hours on Max, and said another pass could have fixed some jump cuts in a later reply.

The downloadable skill

The GitHub repository provides a Claude Code skill, installation instructions, example projects and the animation extensions. It calls for Node.js, Chrome, ffmpeg, yt-dlp and Python with numpy and Pillow; the skill clones ClaudeAnimationBase during setup. LLMJunky identified Claude Code as the environment used for the earlier Papercut run.

The example projects omit the copyrighted songs. The repo's music-rights note says publication requires permission from the rights holders and warns that platforms may mute or remove videos using the tracks.
