Paste rough chapters → YT-ready timestamp block.
A free formatter that converts a rough chapter list into a YouTube-compliant timestamp block (00:00 - Title format). Enforces YouTube's three chapter requirements: first chapter at 00:00, minimum 10 seconds between chapters, and a minimum of three chapters for the feature to activate.
Paste rough chapter list (one per line). The formatter outputs a YT-compliant timestamp block: 00:00 - Title, with chapters spaced according to your video duration, ready to paste into the description.

Who this is for
YouTubers who manually retype chapters into the YT format and waste 5 minutes per upload.
The problem this solves
YouTube requires chapters in specific format: first chapter must start at 00:00, format must be MM:SS or HH:MM:SS, each chapter min 10 seconds. The formatter handles all of this automatically — paste rough notes, get YT-compliant output.
YouTube videos with properly formatted chapter markers see on average 5-8% higher average view duration and 13% higher click-through on description-box links — yet only 26% of mid-tier creators use them.

Frequently asked
What's the required YouTube chapter format?
First chapter must start at 00:00, format must be MM:SS or HH:MM:SS, each chapter must be at least 10 seconds long, and there must be at least 3 chapters total for the feature to activate.
Will the feature still work if I miss one requirement?
No. YouTube silently disables the chapter feature if any rule is broken. The formatter enforces all rules so you never lose the feature to a typo.
How many chapters should a 10-minute video have?
Typically 4-7 chapters. Too few (under 3) won't activate the feature; too many (over 10) fragment the experience. 1-2 minutes per chapter is the sweet spot.
Can I use this for podcast timestamps too?
Yes. Apple Podcasts and Spotify use the same format. The formatter's output works across YouTube, Apple Podcasts, and Spotify show notes without modification.
Does Clipflow generate chapter markers automatically?
Yes — Clipflow's transcript-chapter-generator detects topic shifts in the transcript and proposes chapter markers. Use this formatter when you have rough notes from a manual outline.
