Add Subtitles Using

Video content has quickly become the easiest way to reach a wider audience.  From Facebook to Instagram to YouTube, a great video is sure to break through the social media noise.  But video isn’t always accessible.  Your video could become obsolete if the viewer is hearing-impaired or watching your content without sound.  Enter subtitles.

You’re probably familiar with subtitles already. They’re the text at the bottom of the screen during movie or TV scenes of spoken dialogue.  (They also denote significant noises and music.) They’re used to translate foreign films or TV programming most often.  But they’re showing up more and more in social media videos.  And with good reason.

85% of Facebook videos are viewed without sound.  A large part of your viewership may not experience the best parts of your content-even if your video is compelling and filled with riveting quotes, music, and dialogue.  Thus, subtitles ensure that viewers take away the overall meaning of your content, with or without sound.  Additionally, subtitles produce a 14% lift in engagement if you’re using your video content as advertising.  Subtitles’ impact on the user experience is important because more than 60% of companies are already using video as a primary marketing tool.

Text inside the video is a great way to reach more people and get those people to stick around longer. But they also make your social media content accessible.  Hearing-impaired users often sift through countless user-generated posts that aren’t optimized. Subtitled videos truly stand out in this crowded playing field.  These videos are inclusive, and they’re essentially bulletproof.  Your message gets through, sound or no sound.

Subtitle Formats

You’ll use 1 of 2 file formats when creating subtitles for, and for most social media platforms: the SRT file or the WebVTT file.

SRT files are text files created using SubRip software. They have the .srt extension.  They’re simple text documents that contain video captions as well as timecode.  However, they have no video content or data.  They’re simply a complementary document that adds all your subtitles to the video.  You can create SRT files using a couple common methods. Format it manually in a Text Editor, or use conversion software like SubX, which you can download for free on popular tech sites like CNET.

The WebVTT file (.vtt) is also a text file that stores caption and timecode data.  But unlike the SRT file, it must be encoded using UTF-8. Also, it’s a bit more complex, allowing for comments and more sophisticated styling cues.

How To Get SRT or WebVTT Files?

You could create these files on your own with programs like TextEdit.  Or use, an on-demand media company that offers caption services and transcription for $1 per minute.  Other professional services can cost as much as $3-$5 per minute.

SRT and WebVTT files aren’t the only options, however. Professional transcription services provide captioning services. You also use upload your videos to YouTube, use the native closed captioning function, and download the finished document as an .srt or .vtt. Voice recognition software works as well. Or, manually transcribe the video content yourself.
