What is ddc: Automated Video Generation Skill?
ddc is a professional-grade video automation tool designed to streamline the production of short-form content for platforms like Douyin and TikTok. As part of the Openclaw Skills library, it allows developers and marketers to bypass manual editing by programmatically combining images, neural text-to-speech (TTS), and synchronized subtitles into 1080x1920 MP4 files. The skill focuses on marketing compliance and efficiency, making it ideal for high-volume content generation.
The tool utilizes Edge TTS for human-like narration and FFmpeg for robust video rendering. It includes intelligent features like automatic duration scaling, where the video length is calculated based on the script's word count, and random BGM selection to ensure content variety. By using Openclaw Skills like ddc, users can transform raw assets into brand-compliant marketing videos in under a minute.
