name: download-all-transcripts description: Download transcripts for all data folders sequentially. Use for overnight batch processing or when you need to download pending transcripts across all channels and collections.

Download All Transcripts

Why? Manually downloading transcripts folder-by-folder is tedious and error-prone. This skill automates overnight batch processing across all channels and collections with built-in rate limiting and resumability.

Quick Start

Copy# Run the unified CLI command
ytscriber download-all

That's it. The command finds all folders with videos.csv, downloads pending transcripts, and resumes safely if interrupted.

---

Workflow

1. Verify Prerequisites

Before running, ensure:

• You have at least one folder with a videos.csv file
• The ytscriber CLI is installed (pip install -e .)

Copy# Check for valid data folders
ls ~/Documents/YTScriber/*/videos.csv

[!TIP] If no videos.csv files exist, first run extract-videos or sync-all-channels to populate them.

2. Execute Batch Download

Copyytscriber download-all

The command will:

1. Find all folders containing videos.csv
2. Process each folder sequentially
3. Download transcripts to <folder>/transcripts/
4. Wait 60 seconds between videos to avoid YouTube rate limiting
5. Update CSV with download status

[!CAUTION] This is a long-running operation. For a channel with 500 videos, expect 8+ hours. Run overnight or in a tmux/screen session.

3. Monitor Progress

The command outputs real-time progress:

CopyYTScriber - Download All Transcripts
=======================================
Started at: Thu Dec 26 09:00:00 PST 2024
Delay between videos: 60s

Found 12 folders with videos.csv

────────────────────────────────────────
[1/12] Processing: lex-fridman
  CSV: ~/Documents/YTScriber/lex-fridman/videos.csv
  Output: ~/Documents/YTScriber/lex-fridman/transcripts

4. Handle Completion or Interruption

On successful completion:

CopyAll transcripts downloaded!
Finished at: Thu Dec 26 17:30:00 PST 2024

Summary of folders processed:
  - lex-fridman: 342 transcripts
  - huberman-lab: 156 transcripts
  ...

On interruption or IP block: Simply run the command again. It automatically skips videos where transcript_downloaded=success in the CSV.

Output Structure

Transcripts are saved as markdown with YAML frontmatter:

Copy~/Documents/YTScriber/huberman-lab/
├── videos.csv
└── transcripts/
    ├── 2024-01-15-abc123XYZ00.md
    ├── 2024-01-20-def456ABC11.md
    └── ...

Each transcript file contains:

Copy---
video_id: abc123XYZ00
video_url: https://www.youtube.com/watch?v=abc123XYZ00
title: "Sleep Optimization Toolkit"

Troubleshooting

---

Common Mistakes

1. Running without checking disk space - Transcripts are small (~50KB each), but 10,000 videos = ~500MB. Verify space before overnight runs.

2. Interrupting during a download - Safe to Ctrl+C between videos. If you interrupt mid-download, that video's transcript may be incomplete. The CSV won't mark it as downloaded, so it will retry.

3. Running multiple instances - Don't run the command twice simultaneously. The 60s delay assumes single-threaded operation to respect rate limits.

4. Expecting instant results - The 60s delay is intentional. Faster rates trigger IP blocks. Plan for overnight runs.

Quality Checklist

Before considering batch download complete:

• All folders show transcript counts in summary output
• No IP blocked errors (or resolved by VPN switch)
• Spot-check 2-3 random .md files have valid content
• CSV transcript_downloaded column reflects actual downloads

When to Use This vs. download-transcripts

Technical Details

• Rate limiting: 60 second delay between videos
• Resumability: Based on transcript_downloaded column in each CSV
• Dependencies: Requires ytscriber CLI (pip install -e .)
