Imagine a viewer watching a long tutorial video on cooking. They want to jump directly to the section on how to prepare a specific dish, but without chapters, they’re left scrubbing through the timeline. This is where video chapters come into play. By creating chapters, you can significantly improve navigation, making it easier for viewers to access the information they need.
In this guide, I’ll walk you through the process of AI generated chapters for your videos using the OpenAI API, starting from uploading your video to the FastPix platform. Let's dive right in!
Video chapters are segments within a video that allow viewers to navigate directly to specific topics or sections. YouTube have popularized this feature, enabling users to skip to the parts they are most interested in. For example, a cooking tutorial may have chapters for “Ingredients,” “Preparation,” and “Cooking Time,” allowing viewers to jump directly to the section they need.
Using chapters not only enhances the viewing experience but also improves engagement and retention. When viewers can easily find the information they seek, they are more likely to stay engaged with your content.
Creating chapters manually can be a tedious task, particularly for longer videos. Did you know that you can automate this process with AI? By leveraging the OpenAI API, you can not only streamline chapter creation but also maintain consistency across your content. This approach ensures that your viewers can easily find and jump to specific sections, improving engagement and satisfaction.
Now, let’s explore how to implement this in your videos!
Prerequisites
Before we dive into the implementation, ensure you have the following:
Setting up your OpenAI account
Note: Be sure to save the API key; it will be useful later.
To generate chapters for your video content, start by uploading the video to the FastPix platform.
You can either upload a video using a URL link (pull video) or upload a video from your local machine (push video).
{
"inputs": [
{
"type": "video",
"url": "https://static.fastpix.io/sample.mp4"
}
],
"createSubtitles": {
"name": "name",
"languageCode": "en-us"
},
"accessPolicy": "public"
}
Your media has now been created with subtitles enabled.
Be sure to note the stream URL for that video
First, let’s create a new folder for your project:
mkdir my-video-chapters
cd my-video-chapters
Next, initialize your Node.js project:
npm init -y
This command will create a package.json file, which will manage your project’s dependencies.
Now, we need to install the OpenAI SDK to interact with the API:
npm install openai
Create a new file named chapters.js in your project directory. This file will contain the code to process the subtitles and generate chapters. Here’s a basic structure to get you started:
const OpenAI = require("openai");
const playbackID = '...'; // Replace with your actual playback ID
const streamURL = https://stream.fastpix.app/{playbackId}.vtt;
const openai = new OpenAI({
apiKey: '...' // Replace with your actual OpenAI API key
});
async function init() {
const response = await fetch(streamURL);
const data = await response.text();
const chatCompletion = await openai.chat.completions.create({
messages: [
{ role: 'system', content: 'You are a helpful assistant.' },
{ role: 'user', content: data }
],
model: 'gpt-3.5-turbo',
});
const rx = /(\d+:\d+:\d+(\.\d*)?) - (\d+:\d+:\d+(\.\d*)?)? ?(.*)/g;
const matches = chatCompletion.choices[0].message.content.matchAll(rx);
const output = [...matches].map(match => ({
start: match[1].replace(/\.\d+/, ''),
title: match[5]
}));
console.log(output);
}
init();
Make sure to replace '...' in the code with your actual OpenAI API key. Additionally, if you have a Stream URL for your video, be sure to include it as it will be useful for linking your generated chapters to the actual content.
You can now run your chapters.js file to generate chapters based on your subtitles. Use the following command in your terminal:
node chapters.js
Here’s a competitive breakdown of the uses for chapters in video content:
By leveraging chapters effectively, content creators can differentiate themselves in a crowded market, providing tailored experiences that enhance engagement, accessibility, and overall satisfaction.
Creating chapters for your videos enhances navigation by allowing viewers to jump directly to specific sections, significantly improving their overall experience. This quick access helps maintain engagement, as viewers are less likely to lose interest when they can easily find relevant content.
Chapters also improve accessibility, making it easier for all viewers, including those with disabilities, to navigate and understand your material. Additionally, they aid in information retention; when viewers can revisit specific topics, they are more likely to remember what they've learned.
From an SEO perspective, chapters can help search engines index your content more effectively, potentially increasing your video's visibility in search results. A well-organized video with chapters not only creates a more professional user experience but also facilitates sharing, as viewers can easily recommend specific sections on social media.
Adding chapters to your YouTube videos enhances navigation and improves the viewer experience. Here’s a step-by-step guide on how to do it:
00:00 - Introduction
01:15 - Ingredients
03:45 - Preparation
05:30 - Cooking Time
08:00 - Conclusion
Note: The first timestamp must start at 00:00 for the chapters feature to be activated.
Adding AI-generated chapters to your videos can transform the way your audience engages with your content. These chapters break down long videos into structured, easy-to-navigate segments, helping viewers find exactly what they need without hassle. This not only improves user experience but also increases viewer retention, making your content more impactful.
FastPix simplifies this process with its Video Chapters feature, which uses advanced AI to automatically generate accurate and customizable chapters for your videos. Whether it’s a tutorial, a webinar, or a product demo, this tool ensures your content is organized and professional.
Beyond chapters, FastPix’s In-Video AI tools offer a suite of features to enhance your video workflows, including automated scene detection, subtitles, and keyword tagging. These tools are designed to save you time and effort while elevating the quality of your content.

Yes, many platforms now support chapter creation for live streams, though this is often done after the stream ends. Some platforms use AI to automatically generate chapters based on the content of the stream, but you may need to edit or finalize them once the stream is over.
When creating video chapters, you might face challenges like ensuring accurate timestamps, handling overlapping chapter sections, and managing content updates. AI-generated chapters may also need a manual review to confirm that they align with the video content and make sense to viewers.
AI-generated chapters enhance video accessibility by providing clear, easy-to-navigate segments. Viewers can jump directly to the parts they’re interested in, making it easier to consume content, especially for longer videos. This improves user experience, especially for educational or tutorial videos.
Yes, AI-generated chapters can be customized. Depending on the platform or tool you use, you can adjust chapter titles, timing, and descriptions to better fit your content and viewer preferences. Customization ensures that chapters align with the video’s intent and make navigation more intuitive for viewers.
AI-generated chapters can be added to most types of videos, including tutorials, webinars, and long-form content. However, they work best with well-structured videos, where the AI can easily detect logical segments. For more complex videos, you might need to manually adjust the chapters for accuracy.
Yes, AI-generated chapters can work alongside subtitles or closed captions. The subtitles can provide additional context for each chapter, making the content even more accessible for viewers who rely on them. This combination helps in enhancing both the usability and the accessibility of your videos.
AI-generated chapters are generally quite accurate, but they might require some adjustments. The AI uses algorithms to detect natural breaks in the content, but it’s still recommended to review the chapters, especially for more complex videos, to ensure they align with the intended structure and meaning.
