Ytboob Video: Upd

: While extraction tools like ytboob.live make it easy to grab media, users must respect fair use and not re-upload content they do not own.

Notifications: subscribers may receive a “changed” notification only in limited cases (YouTube generally notifies on new uploads; metadata-only edits usually do not trigger subscriber notifications).
Watch links and embeds: remain valid after metadata and editor changes; if you publish a new video instead, the URL changes.
Analytics continuity: edits via the YouTube Editor keep historical analytics (views, watch time, comments). Re-uploading creates a separate analytics record.
Search & recommendation impact: title/description/thumbnail changes can change CTR and discovery; algorithmic re-evaluation takes time and depends on watch behavior signals.

Plan small iterative metadata tests: change one element at a time (title or thumbnail) and monitor for 1–2 weeks.
Use the YouTube Editor for minor cuts to keep URL and comments.
For major reworks, upload new video and link from original; keep the original if it has significant historical value.
Maintain a changelog in the description or a pinned comment for transparency.
Update captions and translations immediately after edits.
Use API for bulk or automated metadata management; ensure proper error handling and backoff for quota limits.
