10 best video subtitle generators for your social media strategy

Automatically adding subtitles to your videos is the best thing you can do for your social media strategy. Subtitling makes videos more accessible, drives better engagement, and is favored by search engines.

According to Stagetext research, 80% of video content consumers aged 18-24 use subtitles all the time. And as Preply claims, 55% of Americans say it is harder to hear dialogue in shows and movies than it used to be.

But choosing the right tool for the job might be harder than it seems.

Different subtitling solutions can offer a variety of features, but in the end, it all boils down to how effective and seamless the process is.

Let's take a look at a selection of the best auto subtitle generators.

What are the benefits of a video subtitle generator?

When talking about video content consumption, there are three simple things you need to keep in mind.

People sometimes watch video content on mute

There are a ton of situations where people would like to tune off and scroll Instagram for a quick moment. It can happen in a line in the grocery store or at the doctor's office. Now wanting to disturb the people around, a person naturally views all of the content with no sound.

Subtitles are essential to a successful social media strategy.

Your message must reach the audience

You gotta make your content as accessible as possible so that your audience can enjoy it to the fullest extent. And it's not just about putting CTA's in captions: every single word you put out there is set to compel the viewer to engage further: discover more content or make a purchase.

Making subtitles for each piece of video content you produce takes too much time

It may be easy to sit and transcribe the speech component of a single 40-second video. But you might have videos that are 30 minutes long. You can have hundreds of them coming out to a variety of platforms like social media and streaming services.

And we don't have to tell you something you know all too well: when it comes to marketing and promotion, consistency and speed are just as essential to success as the quality of promotional content.

Automated video subtitle generators do help on that front.

How to choose the best video subtitle generator

Making high-quality video content is not the only part of a successful social media strategy.

One of the other important aspects that go into that is the accessibility of said content, which is greatly improved through subtitling. Subtitles enable viewers to enjoy your videos in a variety of situations when they otherwise couldn't hear the audio and also make them more accessible to foreign language speakers and people hard of hearing.

The downside of the subtitle generation is that it is extremely time-consuming. And if watching the entire video, transcribing it, and editing the transcription over the footage isn't bad enough, doing that for hundreds of videos surely does.

In this case, automated subtitle generators are a sure go. When choosing the best tool for the job, you must:

  • Define the purpose of subtitle generation software for you. Then you would have a clear benchmark that you can use to make sure a particular solution has everything you need;
  • After that, see how the software would integrate into your production process to make sure the creators won't have any trouble using it;
  • And lastly, consider the price! Nothing wrong with getting the most bang for your buck, right?
