How it works
When you click Copy in the Chapters panel, Tella copies your chapters as timestamped text like this:Copy chapters for YouTube
- Open your video in the Tella editor.
- Click the Chapters tab in the right sidebar.
- Click Copy. The button tooltip confirms the format is “Formatted for YouTube”.
- Go to your YouTube video and paste the text into the description field.
- Save the YouTube description. Chapter markers will appear on the progress bar.
YouTube chapter requirements
For YouTube to recognize chapters, your description must meet these requirements:- The first timestamp must be 0:00. Tella handles this automatically — if your first chapter starts after 0:00, Tella adds an “Intro” chapter at the beginning when you save.
- You need at least three chapters.
- Each chapter must be at least 10 seconds long.
Timestamp format
Tella formats timestamps based on your video’s length:-
Videos under one hour use M:SS format (e.g.,
0:00,2:30,14:05). -
Videos one hour or longer use H:MM:SS format (e.g.,
1:02:30).
Tips
- Keep chapter titles short and descriptive. YouTube displays them in the progress bar, so long titles get cut off.
- You can generate chapters with AI or add them manually before copying.
- If you enable Auto-generate chapters in Settings > Preferences, chapters are created automatically after each recording’s transcription completes.
