How to do Video Question Answering using JavaScript

In this guide, we’ll walk you through creating a video question answering system using JavaScript.

You'll learn how to analyze video content, answer questions related to specific events or actions, and enhance your AI applications with multimodal capabilities.

By the end, you'll be able to connect natural language queries to visual data, enabling your projects to provide intelligent, context-aware responses from video content.

‍

What is Video Question Answering?

Video Question Answering is the process of answering questions in natural language based on the content of a video.

It integrates computer vision and natural language processing to interpret both the visual elements and the sequence of events in the video.

Unlike static image-based question answering, Video QA requires analyzing dynamic content over time, enabling it to handle tasks such as summarizing scenes, recognizing actions, and tracking changes throughout the video.

Live Test Models on Eden AI

Eden AI provides a platform where you can test different AI models before integrating them, allowing you to evaluate and select the provider that best aligns with your needs.

‍

Install JavaScript's Axios Module

To make HTTP requests from your JavaScript application, we will use Axios, a promise-based HTTP client for the browser and Node.js. To install Axios, run the following command:

npm install axios

‍

Prepare the Code

Here’s how to call Eden AI’s Video QA API in JavaScript:

const axios = require("axios").default;

const options = {
  method: "POST",
  url: "https://api.edenai.run/v2/video/question_answer",
  headers: {
    Authorization: "Bearer YOUR_API_KEY", // Replace with your actual API Key
  },
  data: {
    providers: "google", // Eden AI supports multiple providers
    file_url: "https://your-video-url.com/video.mp4", // Replace with your video URL
    text: "Describe this video?", // Your natural language question
  },
};

axios
  .request(options)
  .then((response) => {
    console.log(response.data);
  })
  .catch((error) => {
    console.error(error);
  });

Explanation of Code Sections

• Authorization Header: This is where your unique API token goes.
• Providers: You can specify "google" or test other providers like "amazon", "microsoft", etc.
• file_url: The link to the video you want analyzed.
  
• text: The question you want to ask about the video content.

‍

Interpreting the Results

When the API successfully processes the video and answers your question, the response will be in JSON format. Here’s an example of what the response might look like:

{
  "google": {
    "answer": "The video shows a man walking through a park during sunset.",
    "status": "success"
  }
}

• answer: This field contains the answer to your question based on the video content. In this case, it describes an action (a man walking through a park during sunset).
  
• status: This indicates the success or failure of the request. If the request was successful, the status will be "success".
