YouTube Timestamp Generator
Create chapter-style timestamps from a list of section names and durations.
Build a clean timestamp list from chapter names and section durations. It is useful while preparing YouTube descriptions, podcasts, courses, and long videos.
How it works
Each line contains a section title and that section's duration. The tool keeps a running total and turns it into the start time for each chapter.
Check the final edit
If you trim clips, change intros, or insert ads after generating chapters, timestamps can shift. Verify the final exported video before publishing.
Keep chapter names useful
Descriptive chapter titles help viewers scan the video. Avoid vague labels when a clearer topic name would be more useful.
Frequently asked questions
Can durations include hours?Yes. Use H:MM:SS when needed.
Does this upload to YouTube?No. It creates text that you can copy into your workflow.
