YouTube Timestamp Generator — Chapters in One Click

Each line in your description should look like “0:00 Intro” — a timestamp in M:SS or H:MM:SS format, a space, then the chapter title. Your first line must be 0:00, you need at least three timestamps in ascending order, and each chapter must be at least 10 seconds long. Blazescribe always produces output that follows these rules.

Yes. YouTube only renders chapters if the first timestamp is exactly 0:00 (or 00:00). If you start at 0:05 or 0:30, chapters won’t appear at all. Blazescribe always anchors the first chapter at 0:00 so your description passes this check automatically.

YouTube requires a minimum of three chapters for the chapter UI to show up, and each chapter must be at least 10 seconds long. There’s no strict maximum, but most creators settle around 5–12 chapters per video for readability.

Today Blazescribe generates chapters from a video you upload. If your raw video is hosted elsewhere, download it once and drag the file in — you get a transcript, chapters, and exports in a single pass.

Both. Blazescribe transcribes the video, detects where the topic changes, and writes a short, descriptive title for each section. You can edit any title before pasting into YouTube.

MP4, MOV, WebM, AVI, and MKV up to 1 GB — enough for most full-length tutorials, podcasts, and webinars. Long files are handled in the background so you can close the tab and come back to the finished chapter list.

Yes — you can try Blazescribe free, generate chapters from your first video, and paste them straight into your description. Paid plans add longer uploads, more monthly minutes, and the full AI content suite (blog posts, show notes, SRT/VTT subtitles, and more).
