How to Adjust and Add Subtitles to Videos

Creating videos continues to be one of the most effective ways to keep people entertained. You can notice it from the millions and millions of views from many video-viewing platforms, led by YouTube, TikTok, Facebook, Instagram, and Vimeo. In fact, Statista says that the number of video viewers online will continue to increase from 2.78 billion people in 2019 to 3.48 billion people in 2023.

Aside from entertainment, videos online have become an effective tool for brands and video content creators. Brands use videos for marketing. Based on the marketing survey of MotionCue on marketing teams, 65% of the marketers want to increase their brand’s awareness, and 64% claimed that creating a video has helped them achieve that goal.

Adjust and Add Subtitles to Videos

Meanwhile, video-viewing platforms, such as YouTube, can pay their video creators depending on the number of views, video length, ad engagement, and more. But with the extreme competition of videos on different social media platforms and websites, how can you increase your videos’ viewership and engagement? Adding subtitles through an auto subtitle generator is the key.

Why Should You Use Subtitles For Your Videos?

As you might probably know, subtitles are the text that usually appears at the bottom of the videos and transcribes a speaker’s speech. Video creators maximize this feature so their videos can reach their true potential. Listed below are the reasons why you should add subtitles to your videos:

  • Increase views and engagement. Video-viewing platforms have recorded an increase in views and engagement when there is a subtitle for a video. In particular, Facebook says view time increases by 12%, on average, with captions on.
  • More accessible. Subtitles can allow foreign language speakers and hearing-impaired individuals to understand the video with the transcription provided.
  • Boost SEO. Since SEO tools rely on keywords, videos with subtitles can rank higher in the search engine than those without subtitles.

Adding and Adjusting Subtitles to Your Videos

If you are a video content creator who wants to upload it on social media platforms or the internet, adding subtitles is the answer to catch more audience. Here are some tools you can use to add and adjust subtitles on your videos:
