youtube-clipper

Overview

YouTube Clipper is a Claude Code skill that provides an AI-powered workflow for downloading YouTube videos, generating semantic chapters, clipping segments, translating subtitles to bilingual format, and burning subtitles into video files. It uses AI semantic analysis to understand video content rather than mechanically splitting by time.

Key Features

• AI Semantic Chapter Generation — Analyzes video content to generate fine-grained chapters (2-5 minutes each) based on meaning, not arbitrary time splits
• Precise Video Clipping — Uses FFmpeg to extract video segments with frame-accurate timing from generated chapters
• Bilingual Subtitle Translation — Batch translates subtitles to Chinese/English bilingual format with 95% API call reduction for efficiency
• Subtitle Burning — Hardcodes bilingual subtitles into video files with customizable styling, requiring FFmpeg with libass support
• Social Media Content Generation — Auto-generates content summaries formatted for platforms like Xiaohongshu, Douyin, and WeChat

Who is this for?

Content creators and video editors who work with YouTube videos and need automated clipping, translation, and subtitle workflows. It is particularly useful for those producing bilingual Chinese/English content or repurposing YouTube videos for Chinese social media platforms.
