# YouTube Transcript

## Overview

Extract YouTube video transcripts, metadata, and chapters using yt-dlp. Output formatted as Markdown with YAML frontmatter, saved to ~/Brains/brain/ (Obsidian vault).

## Quick Start

To extract a transcript from a YouTube video:

```bash
python scripts/extract_transcript.py <youtube_url>
```

Optional: Specify custom output filename:

```bash
python scripts/extract_transcript.py <youtube_url> custom_filename.md
```

## Output Format

### YAML Frontmatter

The generated Markdown includes comprehensive metadata:

- `title` - Video title
- `channel` - Channel name
- `url` - YouTube URL
- `upload_date` - Upload date (YYYY-MM-DD)
- `duration` - Video duration (HH:MM:SS)
- `description` - Video description (truncated to 500 chars)
- `tags` - Array of video tags
- `view_count` - View count
- `like_count` - Like count

### Body Structure

Transcript organized by video chapters (if available):

```markdown
## Chapter Title

**00:05:23** Transcript text for this segment.

**00:05:45** Next segment text.
```

If no chapters exist, all content appears under "## Transcript" heading.

Timestamps formatted as HH:MM:SS for consistency.

## Workflow

1. Extract metadata and subtitles using yt-dlp
2. Parse VTT subtitle format to extract timestamps and text
3. Group transcript segments by video chapters (if present)
4. Format as Markdown with YAML frontmatter
5. Save to ~/Brains/brain/ with sanitized filename based on video title
6. Clean up temporary subtitle files

## Deduplication

To remove duplicates from existing transcript files:

```bash
python scripts/deduplicate_transcript.py <markdown_file>
```

This removes transcript entries that are prefixes of subsequent entries (common in VTT files where subtitles accumulate).

## Requirements

Ensure yt-dlp is installed:

```bash
pip install yt-dlp
```

## Limitations

- Extracts subtitles in English first, falls back to Russian if English unavailable
- Requires video to have subtitles (auto-generated or manual)
- Does not download video or audio files
- Description truncated to 500 characters in frontmatter
