Claude Typer

Workflow

1. Extract the text that should be typed in the animation as prompt.
2. Run:

   • skill_dir=""
     for base in "${AGENTS_HOME:-$HOME/.agents}" "${CLAUDE_HOME:-$HOME/.claude}" "${CODEX_HOME:-$HOME/.codex}"; do
       if [ -d "$base/skills/claude-typer" ]; then
         skill_dir="$base/skills/claude-typer"
         break
       fi
     done
     [ -n "$skill_dir" ] || { echo "claude-typer skill not found under ~/.agents, ~/.claude, or ~/.codex"; exit 1; }
     /usr/local/bin/python3 "$skill_dir/scripts/render_claude_typer.py" "<prompt>"
     

   • Example with explicit size and scale:

     /usr/local/bin/python3 "$skill_dir/scripts/render_claude_typer.py" \
       "claude-typer skill可以让智能体做出提示词打字机动效视频，快来试试吧" \
       --video-width 1080 \
       --video-height 600 \
       --claude-width 600 \
       --scale 2
     

   • Example matching custom runner + remotion params passthrough:

     /usr/local/bin/python3 "$skill_dir/scripts/render_claude_typer.py" \
       "vibe-motion/skills：一个面向智能体的MG动画/视频技能仓库." \
       --runner-prefix "npx -y -p @remotion/cli@4.0.440 -p @remotion/tailwind-v4@4.0.440 remotion" \
       --composition Typer30fps \
       --output-file Typer30fps.mov \
       --codec prores \
       --prores-profile 4444 \
       --pixel-format yuva444p10le \
       --image-format png \
       --audio-codec aac \
       --video-width 1080 \
       --video-height 1080 \
       --claude-width 880
     

3. Return the generated video path in the current working directory.

Rendering Behavior

• Render remote composition Typer30fps from https://www.laosunwendao.com.
• Use @remotion/cli (not remotion package name).
• Prefer bunx @remotion/cli first.
• Fall back to npx -y -p @remotion/cli@4.0.440 -p @remotion/tailwind-v4@4.0.440 remotion if bunx is unavailable.
• Keep transparent MOV defaults:
  • --fps=30
  • --codec=prores
  • --prores-profile=4444
  • --pixel-format=yuva444p10le
  • --image-format=png
  • --scale=2
• Keep defaults for stability:
  • --timeout=300000
  • --concurrency=1
  • Auto-detect local Chrome/Chromium and pass --browser-executable when found.
• Keep default props from the project; replace prompt, and allow overriding videoWidth / videoHeight / claudeWidth through script args.
• Unknown CLI args are passed through to remotion render directly (for advanced flags).
• --runner-prefix lets you fully control the runner command (for pinned versions, global resolution behavior, etc.).
• Exposed Remotion props for this skill are scalar fields only: prompt, typingSpeedMs, model, videoWidth, videoHeight, claudeWidth, tiltStartX, tiltStartY, tiltEndX, tiltEndY, tiltDurationRatio.

Output File Naming

• Save into the current directory as xxx.mov.
• Build xxx by condensing the prompt:
  • Remove common request wrappers like 帮我, 请, 做一个, 生成一个, 制作, 创建 at the start.
  • Remove illegal filename characters.
  • Keep Chinese/English letters and digits.
  • If result is empty, use claude-typer.
• Example:
  • Prompt: 帮我做一个web画板
  • Output: web画板.mov

Notes

• On a clean machine, Node.js + npx is enough for this fallback path, as long as network access to npm and https://www.laosunwendao.com is available.
• If both bunx and npx are unavailable, install one of them and retry.
• If the output name already exists, Remotion overwrite behavior applies.
• If you hit delayRender() timeout, keep --concurrency=1 and raise --timeout-ms as needed.
