Complete the fields above, then generate your options.

Export or prepare a transcript that includes reliable timing throughout the video.

Confirm that labels match the spoken content and that merged sections still begin at the correct timestamp.

Must chapters begin at 00:00?

Yes. A valid YouTube chapter list should begin at 00:00 and contain sequential timestamps.

Does the tool create timestamps from untimed text?

No. It preserves and organizes timestamps supplied in the transcript rather than inventing timing.

Why merge short segments?

Very short chapters can create a noisy viewer experience and unclear navigation.
