## **What is [Video Text Detection API](http://www.edenai.co/feature/text-detection?referral=video-text-detection-javascript)?**

Text Detection API in video refers to the process of identifying and extracting text from videos. It involves using computer vision and optical character recognition (OCR) techniques to analyze the frames of a video and detect any text present within them.

## **Get Started with Video Text Detection API using JavaScript**

The first step is to set Axios, a promise-based HTTP client for the browser and Node.js, that will allow you to call Eden AI API.

Next, you'll need to initialize the File System module in order to access local files on your computer.

‍

Finally, you'll need to create your multipart/formdata parameters form:

### **2. Let’s Extract Text in your Video File**

Now that you have initialized the required JavaScript modules and get your API key, you will be able to extract text in videos. With Eden AI, you can choose which engine you want to use for the Video Text Detection. You can acces the list of Video Text Detection providers available on Eden AI directly on our [documentation](https://docs.edenai.co/reference/video_text_detection_async_create?referral=video-text-detection-javascript).

‍

Here is the JavaScript code to add the form data parameters values for your request:

![https://uploads-ssl.webflow.com/61e7d259b7746e3f63f0b6be/639335a3bff36d79e19778b4_carbon(38).png](https://uploads-ssl.webflow.com/61e7d259b7746e3f63f0b6be/639335a3bff36d79e19778b4_carbon(38).png)

‍

For example, we called two different Video Text Detection engines. Once the parameters values are passed, you can configure your request:

![https://uploads-ssl.webflow.com/61e7d259b7746e3f63f0b6be/63934a7269db61fcef8ec251_carbon(46).png](https://uploads-ssl.webflow.com/61e7d259b7746e3f63f0b6be/63934a7269db61fcef8ec251_carbon(46).png)

‍

Then, you need to create launchJob() function that will execute POST request:

![https://uploads-ssl.webflow.com/61e7d259b7746e3f63f0b6be/639317be6d8df4260a9af1b0_carbon(23).png](https://uploads-ssl.webflow.com/61e7d259b7746e3f63f0b6be/639317be6d8df4260a9af1b0_carbon(23).png)

‍

Finally, you have to create the getJob() function that will execute GET request with the Job ID of your POST request:

![https://uploads-ssl.webflow.com/61e7d259b7746e3f63f0b6be/63934ab7bff36d715698bf95_carbon(48).png](https://uploads-ssl.webflow.com/61e7d259b7746e3f63f0b6be/63934ab7bff36d715698bf95_carbon(48).png)

‍

You will first get this response:

‍

Once the request is done (status : finished), you will be able to get the result for Text Detection task:
