Start with a clean timeline
Use the actual media timeline as the source of truth. Chapter rows should be ordered and should not contain duplicate or backward timestamps.
Write chapter titles for scanning
A viewer should understand the section quickly from the title. Prefer descriptive labels over repeated keywords.
Validate before pasting
The workbench flags malformed and unordered timestamps before generating the final block. Platform-specific eligibility can still change, so verify important uploads in YouTube Studio.
Keep CSV as an editorial source
The editable CSV makes it easier to revise chapter titles or reuse the timeline in show notes, subtitles, or production documentation.
