youtube-clipper turns a YouTube URL plus a timestamp range into share-ready clips — video, GIF, subtitled snippets — without manual video-editing software.

What it can produce

• .mp4 clips — at specified resolution and aspect ratio
• Vertical .mp4 (9:16) — for 小红书, TikTok, Reels
• .gif — short loops for tweets and articles
• .srt subtitle files — with optional translation
• Burned-in subtitles — embedded into the video for platforms that don’t render captions

Where it shines

• Reaction / commentary content — clip a moment, share with caption
• Tutorial highlights — pull the “here’s the key part” moment from a long video
• Social content — same source, multiple aspect ratios for different platforms
• Subtitle translation — pull EN captions, translate to ZH, burn in

Why it’s useful

YouTube videos are 10-60+ minutes long; social audiences want 30 seconds. Manual clipping in DaVinci or Premiere takes 20-30 minutes per clip. This skill collapses that to a single command.

Composes with

• wechat-article-writer — embed clips into articles
• document-illustrator — companion vertical content for 小红书 posts
