As your operation grows, you will need to update descriptions across your entire video catalog -- new Gumroad link, new affiliate program, updated disclaimer. Doing this manually for hundreds of videos across 11 channels would take hours. bulk_update.py does it in minutes.

What It Can Update

• Description text (full replacement or append)
• Tags (add, remove, or replace)
• Product links (find-and-replace within descriptions)
• Thumbnails (if you provide a replacement image)

Rate Limiting

The script automatically rate-limits its API calls to stay within YouTube's quota limits. For large catalogs (1,000+ videos), it processes in batches and spreads the operation across multiple days if necessary. You run the command once and the script manages the pacing automatically.
