YouTube Transcript API: How to deal with Video Content? | by jawad ahmad | Nov, 2023

In today’s digital era, video content plays an essential role and has become a dominant force on the internet. Video content ranges from educational tutorials to entertainment, cartoon animations, sports, etc. On YouTube, video content is consumed by millions of people worldwide.

YouTube, the largest video-sharing medium, hosts an incredible amount of content, with over 2.70 billion active users. With this immense fame, it’s no surprise to say that YouTube has a major impact on online communication and information sharing.

But if a person has a hearing impairment, would he prefer to watch or read the content? Obviously, he would try to get access to the video transcript rather than watch the entire video.

In this comprehensive guide, we will explore the YouTube Transcript API and why it’s important to utilise it. We will also see how to use it for video transcription tasks with a hands-on implementation in Python.

The YouTube Transcript API is a great tool that allows developers to programmatically extract transcripts or captions from YouTube videos. A transcript is essentially a written version of the spoken content in a video. Captions, on the other hand, can include both spoken words and descriptions of relevant sounds, making content even more accessible for individuals with hearing impairments.

This API provides a bridge between the dynamic world of video content and the easily searchable world of text. It opens up numerous opportunities in various domains, including accessibility, content analysis, content localization, search engine optimisation (SEO), and beyond.

One of the essential aspects of the YouTube Transcript API is its contribution to accessibility and inclusivity. By making the transcript or captions of a video available, content creators can ensure that their material is accessible to a wide audience, including individuals with hearing impairments.

The transcripts can be used to provide closed captions for videos, allowing viewers to read the descriptions while watching. This makes it possible for deaf or hard-of-hearing individuals to indulge in video content. Moreover, it benefits those who prefer to read, non-native speakers who might find it easier to follow along with written text, and individuals in noisy places where they can’t play audio.

The YouTube Transcript API offers powerful capabilities for content analysis and searchability. Content creators and businesses can use the extracted transcripts to gain insights into their video content. This includes analysing the spoken content, detecting keywords, and identifying frequent words through the word cloud.

For content creators, this means understanding what topics or phrases resonate with their audience, helping them prepare their future content to match the interests of their followers. Businesses can utilize this insight to better target their audience and create content that matches their marketing campaigns.

The YouTube Transcript API is not just about understanding English-language content; it’s a vital tool for content localization. By extracting transcripts, programmers can translate video content into multiple languages, making it accessible to a global audience. This is particularly useful for international businesses and content creators aiming to reach diverse markets.

Translating videos into multiple languages nurtures a video’s reach and can attract viewers who prefer content in their native language. It also allows businesses to prevent language barriers and communicate their message to a worldwide audience.

Search engine optimisation is a crucial aspect of the online content world. Websites and platforms aim to optimise their content to rank higher in search engine results. With the YouTube Transcript API, video creators can significantly nurture their SEO.

The extracted transcripts can be used to generate metadata, tags, and descriptions for video content, all of which are essential for search engine optimization. By utilising relevant keywords and phrases from the transcript, content creators can improve their videos’ visibility on major sites like YouTube and Google.

Using the YouTube Transcript API involves some technical steps, but it’s a process that many developers and businesses find manageable. Here’s a general overview of how to use the API:

First of all, we need to install the Youtube Transcript API through the Anaconda prompt using the below command;

pip install youtube-transcript-api

Once it is installed in the Jupyter Notebook or Google Colab (if you are using the cloud platform) then the next step is to import it.

from youtube_transcript_api import YouTubeTranscriptApi as yta

import re

Then provide the video URL either a full URL address or a specific key and it will work in both cases for you.

video_id= ‘65yXoFc5stI&t=523s’

This code likely retrieves a transcript for a video with the specified video_id using the variable or function yta.

data= yta.get_transcript(video_id)

The end result is that the transcript variable will contain the concatenated ‘text’ values from all dictionaries in the data list where the key is ‘text’. If the key is not ‘text’, nothing is added to the transcript.

transcript= ‘’

for value in data:

for key,val in value.items():

if key== ‘text’:

transcript += val

This code splits the transcript string into a list of lines using line breaks, then joins them into a single string with spaces between lines, creating final_tra.

l= transcript.splitlines()

final_tra = “ “.join(l)

This code opens a file named “TED Talks.txt” in write mode, writes the content of the final_tra string to the file, and then closes the file.

file=open(“TED Talks.txt”, ‘w’)



This code opens the “TED Talks.txt” file in read and write mode, reads its content into the text variable, and then returns the content of the file as a string.

text = open(‘TED Talks.txt’, ‘r+’).read()

While the YouTube Transcript API offers a wealth of benefits, it’s essential to be aware of potential challenges. Here are some key takeaways:

  • Transcripts generated by the API may not be 100% accurate. The quality of the transcript depends on various factors, including the precision of the audio in the video.
  • The API primarily supports significant languages such as Python, so if your content is in a less commonly spoken language, the accuracy of the transcripts might be lower.
  • Google Cloud Platform has usage limits for API requests, and exceeding these limits can result in additional charges.
  • Ensure that you have the rights to access and use the transcripts from YouTube videos, particularly if you plan to repurpose the content.

The YouTube Transcript API is a major advancement in making video content accessible, searchable, and analyzable. It empowers content creators, developers, and businesses to generate more inclusive videos and improve content strategy. This technology bridges the gap between media forms, benefiting both creators and consumers at the same time.

YouTube Transcript API nurtures content accessibility and analytics, providing precision transcription, timestamp insight, and language support for content creators and businesses, improving video SEO and user experiences.
