The challenge with long videos

Long videos can be overwhelming. Whether it’s a marketing pitch, a training session, or an educational lecture, viewers often drop off early not because the content isn’t valuable, but because they struggle to find the key insights quickly.

That’s where AI-powered video summarization comes in. By automatically distilling lengthy videos into concise, engaging summaries, businesses and creators can make content more accessible, keep audiences engaged, and deliver value in a fraction of the time.

Why summarize your video content?

AI-driven video summaries help you:

  • Improve accessibility for viewers who prefer reading over watching.
  • Save time for those who need key insights quickly.
  • Enhance SEO by generating searchable text content.
  • Repurpose videos effortlessly across different platforms.
  • Create structured show notes for podcasts, webinars, and video series.

The problem with manual summarization

Summarizing a video manually is time-consuming and inefficient. Watching hours of footage, identifying key moments, and condensing them into a digestible format takes significant effort especially at scale. For businesses producing large volumes of video content, this process isn’t sustainable.

Manual summarization also introduces inconsistencies. Different people may highlight different points, leading to summaries that vary in quality and focus. Plus, manually creating summaries for every video format text, short clips, or bullet-point takeaways requires additional work.

AI-powered video summarization eliminates these challenges by automating the process, ensuring consistency, and delivering structured summaries in seconds.

What is AI powered video summarization?

AI-powered video summarization leverages artificial intelligence, machine learning, and natural language processing (NLP) to analyze and extract meaningful highlights from videos. These systems identify crucial moments, key topics, and important dialogues, providing a condensed version without losing essential context.

There are two primary types of AI video summarization:

  • Extractive summarization – Selects the most relevant segments from the video and compiles them into a shorter version.
  • Abstractive summarization – Uses NLP to generate a textual summary in a human-like way, rephrasing content for better readability.

By automating video summarization, AI helps businesses, educators, and content creators deliver insights faster, improve accessibility, and repurpose content efficiently—without the bottlenecks of manual editing.

Foundation of AI summarization

Natural language processing (NLP)

NLP is a key component in AI summarization, enabling the system to process, understand, and generate human language. NLP techniques like named entity recognition, topic modelling, and sentiment analysis help identify essential information within transcripts.

Machine learning and deep learning

AI models, particularly those using deep learning, are trained on vast amounts of video and text data to improve summarization accuracy. Transformer-based architectures like BERT and GPT enhance the system's ability to generate coherent and contextually relevant summaries.

Computer vision and audio processing

Beyond text analysis, AI models can use computer vision to analyze visuals and detect important events within a video. Combined with speech recognition, these technologies enable comprehensive content summarization.

How AI summarization works

AI-powered video summarization involves multiple stages, combining speech recognition, text analysis, and machine learning to generate concise, meaningful summaries.

  • Speech-to-text transcription: AI converts spoken words into text using speech recognition models like Whisper.
  • Natural language processing (NLP) : The transcribed text is analyzed to identify key themes, topics, and sentiments.
  • Important segment detection : Machine learning models detect and prioritize the most informative sections of the video.
  • Summary generation: The system either extracts key segments (video-based) or generates a textual summary (text-based).

While AI simplifies this process, implementing it effectively requires the right tools. This is where FastPix comes in providing a streamlined way to generate video summaries without the complexity of managing AI models and infrastructure. Next, we’ll explore how FastPix makes AI-driven summarization effortless and scalable.

Generating AI-powered video summaries with FastPix

FastPix simplifies video summarization by automating the process through its API. Whether you're working with new uploads or existing media, FastPix enables quick extraction of key insights without manual effort.

Why Use FastPix for video summarization?

  • Automated & accurate: FastPix leverages AI to identify important moments, ensuring your summaries retain essential information.
  • Fast processing: Get a summarized version of your video within seconds, saving time and effort.
  • Easy integration: Use FastPix's API to incorporate video summarization into your workflow for automation.

Getting started

FastPix provides two ways to generate AI-powered video summaries:

  • New media uploads : Generate summaries while uploading new video content.
  • Existing media : Apply AI summarization to media files already in your FastPix workspace.

Generating summaries for new media

When uploading a new video, you can enable AI summarization by including the appropriate parameters in your request.

Step 1: Upload or provide a video URL

You can either:

  • Use the upload media API to send files directly from your device.
  • Use the create media from URL API to pull content from a hosted source.

Step 2: Send a request with summary parameters

Ensure your request includes:

  • type: Specify if the media is a video.
  • url: Provide the video file’s URL (if using URL-based upload).
  • generate: Set to "true" to enable summarization.
  • summaryLength: Define the desired summary length (default: 100 words).

Example request (New media from URL)

1{
2  "inputs": [
3    {
4      "type": "video",
5      "url": "https://static.fastpix.io/sample.mp4"
6    }
7  ],
8  "summary": {
9    "generate": "true",
10    "summaryLength": 120
11  },
12  "accessPolicy": "public",
13  "maxResolution": "1080p"
14}

Generating summaries for existing media

If you need to generate a summary for a previously uploaded video, use the generate video summary API.

Step 1: Identify the media file

Retrieve the mediaId of the video you want to summarize.

Step 2: Send a summary request

Make a PATCH request to the /on-demand/<mediaId>/summary endpoint with the following parameters:

  • generate: Set to "true".
  • summaryLength: Define the length of the summary.

1{
2  "summary": {
3    "generate": "true",
4    "summaryLength": 120
5  }
6}

Retrieving the summary

Once the AI summarization is complete, FastPix sends an event notification (video.mediaAI.summary.ready) containing the generated summary.

1{
2  "type": "video.mediaAI.summary.ready",
3  "object": {
4    "type": "mediaAI",
5    "id": "69f82b00-151c-45d4-942c-6eab719143b2"
6  },
7  "data": {
8    "summary": "This is a brief summary of the video content, highlighting the key points and important aspects."
9  }
10}

Key considerations

  • The maximum summary length is 250 words, and the minimum is 30 words.
  • If no summaryLength is provided, the default is 100 words.
  • Ensure you correctly reference the mediaId when summarizing existing media.

FastPix eliminates the complexity of AI-driven summarization, allowing developers to extract meaningful insights from video content with just a few API calls. To know more in detailed, please go through our docs and guide.

Benefits of AI powered video summarization

Saves time

AI-generated summaries allow users to quickly grasp the core message of a video without watching the entire duration. This is especially useful for professionals, students, and decision-makers who need to process information efficiently. Instead of sitting through an hour-long video, they can access a brief summary highlighting key insights.
