Video Captioning and Subtitles

The Americans with Disabilities Act requires all multimedia made for government, entertainment, education, and business have captions available for the deaf and hard of hearing community.

So why add captions or subtitles to videos that don’t fall under the Disabilities Act, like personal videos for YouTube or social media? Including the Deaf community and non-English speakers is not only inclusive, but it also helps you gain followers. Videos with captions or subtitles receive a 40% boost in views and are more likely to be watched to the end, which helps your YouTube rank. Additionally, 80% of Facebook videos are watched on mute which means videos without captions are getting skipped.

Captions and subtitles are important and necessary for follower growth. But how can someone add captions without hiring an expensive third party?

We recommend using PowerDirector. It is an editing software and app that allows a beginner to add captions and subtitles in a few easy steps. This article will explain the ins and outs of captions and subtitles and how to add them using PowerDirector.

Download PowerDirector for your device of choice and follow our simple step-by-steps to add captions to your videos in no time.

What is the Difference Between Captions and Subtitles?

Captions are a written version of the dialogue in a video, written in the same language as the medium. Captions assume the viewer can’t hear (either because they are hard of hearing or because they are watching with the sound off) and includes music cues, sound effects, and speaker changes.

Subtitles are a translation of the dialogue for people who don’t speak the same language as the medium.

Standard subtitles assume the viewer can hear the audio and don’t include the audio cues like music and sound effects. Subtitles for Deaf and Hard of Hearing (SDHH) are translated into the viewer’s language and also include audio cues.

Tips for Writing Video Captions

Writing captions for social media posts is different from transcribing dialogue for a film or television show. Since most people will be watching your videos with the captions on and sound off, it is important your words draw people in and keep them watching.

Know Your Audience

Using the lingo or slang of your demographic will make the viewing experience more personal for your followers. Don’t be too alienating with your words, as you don’t want to exclude anyone outside your target demo.

Hook Them With the First Line

The hook is the most important part of writing. It draws readers in and makes them want to read more.

The first sentence of your video is all most people will read, so it needs to capture attention and do it fast. But how can you get viewers to stop and watch your video when they are quickly scrolling through a haystack of content?

Here are some ways to draw viewers in:

  1. Use humor
  2. Quote Shocking statistics
  3. Personal success story
  4. Explain viewers pain points and how you can help

Keep it Short and Sweet

We live in a visual age. Your visuals should remain soothing and uncluttered. So keep captions short and don’t obstruct your visuals.

You only have a few seconds to get people’s attention, so pack a punch with as few words as possible.

Include a Call to Action

A Call to Action (CTA) is when you ask viewers to Like, Share, Subscribe, etc. to your channel or post. You can also link to your website or store. Viewers who watched your video to the end have already given you a stamp of approval, so don’t be afraid to ask for the next step.
