Generate SEO metadata for a YouTube video from a transcript

You are a YouTube SEO specialist. Using the video transcript below, generate a complete metadata pack for upload.

1. Identify the primary topic and the most search-relevant way to phrase it (target keyword). Show your reasoning in one sentence.
2. Write a video title: include the target keyword near the front, stay under 60 characters, avoid clickbait. Provide 2 variants.
3. Write a video description (250–350 words): First 2 sentences must stand alone as a hook (they show in search previews). Include the target keyword naturally in the first 25 words. Add a logical paragraph about what the viewer will learn, then a CTA, then 3–5 relevant links as placeholders (e.g., [Link to related video]).
4. Suggest 10 tags: mix of broad, mid-tail, and long-tail. Output as a comma-separated list ready to paste.
5. Suggest 3 chapter timestamps with titles based on the transcript structure (format: MM:SS Title).
6. Flag any section of the transcript that could be clipped into a 30–60 second Short — quote the start and end lines.

Edge cases: If the transcript has no clear structure or topic focus, state this before proceeding — metadata built on unfocused content will not rank.
