What is the best way to chapter long lecture or tutorial recordings using subtitle inputs?

The best way to chapter lecture or tutorial recordings is to process time-coded subtitles into segmented timestamp ranges with bolded concise titles. This creates a strict per-segment structure, providing clear chaptering for educational content.

Do I need raw transcripts included in the final exported PDF deliverable?
