Antigravity AI Agent 技能，用於 ffmpeg 優化 — 編碼階梯、壓縮與可交付的匯出。
此技能為 Antigravity AI Agent 提供一個專用的 ffmpeg 優化工具，專注於高效率的影片編碼與壓縮。它能夠自動產生編碼階梯（encoding ladders），適用於不同平台與頻寬需求，確保影片在維持合理畫質的同時，達到最佳檔案大小。此外，技能支援生成「可交付就緒」(delivery-ready) 的匯出檔案，可直接用於上傳或發布，減少後期手動調整的步驟。此技能在支援檔案操作的 AI Agent 環境（如 Claude Code、Coder 等）中發揮最佳效果，透過系統化的 ffmpeg 參數調整來提升編碼效率。
