WeChat 2D Render

Workflow

  1. Use scripts/render_wechat_2d.sh from this skill.
  2. Pass workspace_dir as the first argument when the user specifies a folder; otherwise use the current directory.
  3. Pass output_path as the second argument when the user specifies output; otherwise use out/wechat-2d-transparent.mov.
  4. Pass a props JSON path as the third argument when the user provides custom Remotion props; otherwise use shared/project/render-presets/default.json.
  5. Run the script and wait for completion.
  6. Return the final absolute output path printed by the script.

Command

bash scripts/render_wechat_2d.sh [workspace_dir] [output_path] [props_file]

Installed Skill Resolution

Use the installed skill copy, not the source repo checkout:

skill_dir=""
for base in "${AGENTS_HOME:-$HOME/.agents}" "${CLAUDE_HOME:-$HOME/.claude}" "${CODEX_HOME:-$HOME/.codex}"; do
  if [ -d "$base/skills/wechat-2d-render" ]; then
    skill_dir="$base/skills/wechat-2d-render"
    break
  fi
done
[ -n "$skill_dir" ] || { echo "wechat-2d-render skill not found under ~/.agents, ~/.claude, or ~/.codex"; exit 1; }

bash "$skill_dir/scripts/render_wechat_2d.sh" "$(pwd)" "$(pwd)/out/wechat-2d-transparent.mov"

Behavior

  • Reuse local repo if workspace_dir/wechat-2d exists; otherwise clone from GitHub.
  • Track remote default branch (origin/HEAD) when updating an existing repo.
  • Install dependencies with pnpm install; if pnpm is missing, enable it through corepack.
  • Run the project Remotion scripts:
    • pnpm run remotion:ensure-browser
    • REMOTION_OUTPUT=... REMOTION_PROPS_FILE=... pnpm run remotion:render
  • Default render target is the active composition from shared/project/projectConfig.js, currently the wechat-chat-motion plugin via ScaffoldDemo30fps.
  • Default output is ProRes 4444 with yuva444p10le pixel format and PNG image format, suitable for transparent-background workflows.

Project Notes

  • The project uses a scaffold/plugin split:
    • preview/* for local UI controls and browser preview.
    • remotion/* for Remotion entry wrappers.
    • shared/scaffold/* for common runtime.
    • shared/project/* for plugin and composition registry.
    • shared/features/demoMotion/* for the WeChat chat scene.
  • Animation state must be deterministic per frame. Remotion renders frames in parallel and out of order, so do not rely on timers, mutable cursors, previous renders, or render order.
  • Frame-specific data should be built from {frame, fps, loop, sceneContext, pluginParams} in buildSceneProps.
  • Keep videoWidth and videoHeight as layout props; use a props JSON file for custom sizes.

Requirements

  • git
  • node
  • corepack or pnpm
  • network access for clone/update and dependency install
