Why should you add captions to YouTube videos?

The main reason to add captions to YouTube videos is to increase accessibility. Captions ensure that viewers who are deaf or hard of hearing, as well as those watching without sound, can fully engage with your content, making it inclusive and accessible to a broader audience.

1. Accessibility

Captions make your videos accessible to viewers who are deaf or hard of hearing, ensuring everyone can engage with your content.

2. Engagement

Captions keep viewers focused and help them follow along, especially in videos with complex information or fast speech, which can boost watch time and engagement.

3. Sound-Off Viewing

Many viewers watch videos without sound, especially on mobile. Captions allow these viewers to understand and enjoy your content without needing audio.

4. Discoverability

Captioned videos provide additional context that YouTube can index, increasing the likelihood your content appears in relevant search results.

5. Clarifies Content

Captions help when watching in noisy environments and can aid non-native speakers, enhancing understanding and viewer experience.

How to Add Subtitles to a YouTube Video that IS NOT yours

Answer: To add contribute with subtitles to someone else’s video, create a SRT/TXT file with the subtitles + timestamps. Then, contact the video’s creator and sed them the file.

This is what your file would look like when finished:

Text File (.SRT) with a YouTube Video's Subtitles, opened in Google Chrome
Subtitles file previewed in Google Chrome

Step-by-step process:

  1. Create a new Text File
  2. Type in the subtitles, along with their timestamps
  3. Save the document
  4. Contact the video’s maker and send them the file

All of this is rather up to the creator. You do the work, but they have to approve it.
