How to turn an SRT transcript into useful YouTube chapters.

A timestamped subtitle file is a good source of evidence for chapters, but it doesn't automatically tell you where the important topics start. Here's how to use it without inventing chapter timings.

Step 1: Start with the real subtitle file

Export a SubRip (.srt) file or WebVTT (.vtt) file from your editing workflow. The file should contain cue start times and the spoken words. For example:

1
00:00:00,000 --> 00:00:06,200
Welcome. Today we'll learn how to plan chapters.

2
00:00:30,000 --> 00:00:43,500
Step one is to clean up the transcript.

3
00:01:20,000 --> 00:01:35,500
Now we'll turn those notes into a short video.

This example has three cues, not necessarily three full topic boundaries. Listen to the corresponding edit before deciding the chapter list.

Step 2: Extract an editable transcript

Open the CueShift free subtitle converter. Paste the SRT or load the file, then export as Markdown or plain text. Readable paragraphs make topic transitions easier to spot and more useful when you ask an AI assistant to summarize.

Step 3: Ask AI to suggest chapters, not fabricate time codes

Open the real CueShift AI chapter generator, select YouTube chapters + video title and paste a short excerpt. The AI can suggest logical sections, but a text-only sample cannot establish precise start times unless you've supplied them. Our prompt specifically tells the model to mark missing timestamps as TBD.

Any proposed chapters should be rewritten after reviewing the actual full-length video. AI suggestions can be incomplete, repeat similar sections or invent context.

Step 4: Format chapters in YouTube Studio

YouTube's own instructions say the first timestamp must start at 00:00, with at least three ascending timestamps and chapter sections of at least ten seconds. Add the list in the video's description, then save.

00:00 Introduction
00:30 Clean up the transcript
01:20 Turn notes into short clips

These are worked examples, not verified markers for your own video. Double-check whether the start of every section actually matches the edit. YouTube may require access to advanced features. See YouTube's official chapter instructions.

Step 5: Check before publishing

Play the first few seconds of each chapter on desktop and mobile. Check chapter title clarity, chronological order, timestamps, words in quotes, and whether a chapter skips an important point. Do not paste a chapter list generated from a five-minute transcript excerpt into a 45-minute video without reviewing the rest.

For multi-episode courses and podcasts

Our Batch Studio converts up to three local subtitle files at once for free. The planned one-time Pro download raises that limit to 200 files per batch and contains publishing prompts and QA checklists. The batch converter runs locally; optional AI processing sends only the selected excerpt when you expressly request it.
