How to Add Subtitles to a Video Automatically?

Regardless of where you plan to share videos, make it a rule to never share any video without a caption or subtitle.

Here are a few ways to add subtitles automatically:

Adding subtitles to your videos using HappyScribe

Unless you want to manually type out a long word document or text file consisting of your subtitles, you can use transcription services to make your job easier. 

HappyScribe is one of the most intuitive and accurate transcription services that efficiently transcribe your video to create captions and subtitles.

It’s a service that walks the walk and doesn’t make numerous claims about its efficiency and accuracy. 

Apart from converting videos to text, HappyScribe offers punctuation functionality.

It supports a vast collection of languages, allowing you to convert your videos into text in the language of your choice.

Here are three steps to follow for adding subtitles automatically to your videos:

  • Upload your video

As it’s a cloud-based platform, you don’t have to down and install an application.

Start by uploading your videos on HappyScribe’s website. This  platform supports .mp4, .mov and .avi extensions for uploading videos.

You can directly upload video files from your computer. 

When you upload your video, HappyScribe asks you a few questions about the quality of your video. Answer them and click on “Proceed.”

Next, select your video file. Using this intuitive platform.

You can browse files from your computer, import from different channels, or simply drop your video files that require a subtitle. 

Next, select the language used in your video.

After choosing the language, select between machine-generated or human-made transcription services of HappyScribe.

  • Customize your video

After HappyScribe converts your videos into text, you’re redirected to their editor.
Where you can add timecode, edit subtitle limit, format subtitles, translate into a different language, and proofread.

You can even change the font, color, and position of the subtitles using this editor.

However, you will want to ensure that the color and font type you select for your subtitles complement your video design.

Though subtitles placed at the bottom works best, you can reposition the text anywhere on your video. 

For making your videos engaging, consider using a contrasting color for the text of your subtitle to make it readable.

Also, when customizing subtitles, avoid putting in too much text.

Two lines of text below your video are apt and deliver exceptional results.

  • Download your file

After customizing your subtitles, you can download subtitles in a desirable file format. HappyScribe supports a host of extensions to choose from. 

Interestingly, HappyScribe allows you to download the video with subtitles for you to watch and make necessary changes.

Benefits of adding subtitles to your videos

Apart from increasing reach and targeting a wider audience base, adding subtitles can bring a paradigm shift in your marketing metrics.

Some benefits of adding captions to your videos are:

  • Enhances accessibility

Video content with subtitles makes your content accessible to deaf or hard-of-hearing viewers.

If your video has dialogues, these people may not hear and understand the message your video is trying to convey.

With US federal laws like the Americans with Disabilities Act (ADA) and the UK’s federal law like the Communication Act of 2003.

Including subtitles below your video has become more than necessary.

Interesting statistics: With 28 million Americans hard-of-hearing, adding subtitles can make you reach this whopping number of customers.

  • Enhances the watch time and engagement

Usually, employees prefer to watch videos on mute during their working hours lest they disturb someone around them.

Also, when traveling or while working, turning the sound on isn’t always a possibility.

When you don’t add subtitles to your videos, you miss out on the probability of reaching people who watch videos on mute.

Captions and subtitles have a significant impact on your watch time and engagement rate.

Interesting statistics: Videos with subtitles increase the view time by 12% and watch time by 91%.

  • Enhances comprehension

Most viewers are not visual learners, and they’re not going to comprehend much from your video unless it has a subtitle or a caption. 

Also, people who are avid readers are likely to learn and comprehend more from videos with subtitles.

As a brand, understand that the combination of video and text is stronger than using just videos to attract your audience’s attention.

Interestingly, even native speakers of a certain language are more likely to switch on subtitles to understand the video content better. 

With so much on the table, investing in a transcription service providing automatic subtitles for every video you create makes complete sense.

Interesting statistics: Of the 7.5 million people in the UK who used subtitles or closed captions, only 1.5 million were people with hearing impairment.

This implies that even people who can hear properly prefer playing videos with subtitles or closed captions.

  • Ensures your audience understand your language

Great video content can transcend language boundaries with ease, but only when all content is translated.

Your products or services may be global, but if the content you share focuses on one language, your products may fail to reach the global audience.

You expect the viewers to watch content worldwide, but if they can’t understand what it means, all your efforts go down the drain.


So, consider your target audience’s preferences when adding subtitles to your videos.

Also, whenever possible, offer subtitles in multiple languages to let your customer choose a language of their choice.

Interesting statistics: There is a growing need to add subtitles other than English because only 360 million people worldwide speak English; others have a different native language.

  • Improves SEO

Search engines can identify short and long-text search queries to show results matching these keywords.

But, search engines are not trained to transcribe a video and search for a keyword in a transcribed file.

However, the text you upload along with your video contributes to your video’s ranking in search engines.


Whether it’s Google or Bing, you can extract subtitles from a video and ensure your videos are part of the search engine ranking process. 

Interestingly, by adding English captions or subtitles, you target only English keywords, and your video is likely to rank only for English keywords.

Adding Hindi, Italian, Spanish, Chinese, or Japanese subtitles can help you rank for keywords in these languages.

As a result, you can target local SEO keywords and build a brand that everyone knows in the neighbourhood.

Multi-language subtitles are a great way to reach Hindi-speaking, Chinese, Japanese, French and Italian viewers.

Interesting fact: As Google and other search engine’s crawl for external information like length of the video, engagement rate, and duration without analyzing the content,

Adding videos to subtitles makes your content SEO-friendly and increases your chances of getting ranked in SERPs

Wrapping up

If you’re in a dilemma of what kind of videos require subtitles and captions, the answer is – almost every video that you create for increasing customer engagement and spreading brand awareness.

Subtitles in your videos increase your viewership by connecting with your customers that very few companies take care of – hard of hearing and deaf viewers.

By reading subtitles in your videos, deaf people can enjoy your video and become lifetime customers. 

The presence of subtitles can elevate your marketing efforts and help you reach a wider audience in no time.

While the benefits of adding text below your videos are countless,

Businesses with a large following on video-consuming social media platforms like TikTok, Instagram, and Facebook fail to give importance to subtitles. 

These brands taste failure because they let the benefits of adding captions slip away from their hand.

Have you used subtitles before? Do you write them manually or use a transcription service to create one automatically?
