So, you’ve created a video and want to share it with the world? Before you upload your video, you should think about creating your closed captions to appear alongside it. Luckily, YouTube helps creators to add their own captions or subtitles to their content. Closed captions help more people engage with your content and help to ensure that your content is easily searchable. 

In this article, you’ll learn how to write your own closed captions for YouTube videos and which software can help to make the process easy. 

How to write closed captions for YouTube videos from scratch

If you want to write your own captions from scratch, this can be easily done in a standard text editor such as Microsoft Word or in the Notepad app. Here’s how: 

  1. Open the text editor of your choice
  2. For each caption, write its number on a new line in chronological order. 
  3. Below each number, you’ll need to add the time stamp of the audio you want your captions to appear on. Use the following formatting: in HH:MM:SS,MS. e.g. 00:00:03,10 is 3 seconds 10 milliseconds. 
  4. After writing the time stamp add the following text –> ensuring that a space is on either side. 
  5. After the –> write the time code that you want the text to disappear 
  6. On the next line, in this case: (2.) write your next caption 
  7. Repeat the process until your file looks similar to this: 


00:00:14,000 –> 00:00:20,500

Because speech comes in many different waves and shapes called waveforms.

8. Once your file is complete and you’re happy, export the file as a .TXT file. 

9. You will then need to convert the .TXT file as an SRT file so that you can burn the captions into your video or upload it alongside your video when adding it to YouTube. A TXT to SRT converter can do this automatically for you. 

10. Upload your SRT file to your YouTube video. 

Writing your own captions for YouTube videos can take a lot of time. For every minute of audio it can take up to 10 minutes to transcribe and time stamp correctly. Writing your own captions should only be done if you are on a tight budget, have a lot of spare time, and have only short videos.

Luckily, there is technology out there that can help speed up the process for you!
