How To Generate Auto-Captions and Subtitles on YouTube

Besides having a library of millions of videos, YouTube offers another helpful feature. YouTube can auto-generate subtitles for your videos. When you upload a video, YouTube generates closed captions that viewers can turn on or off. That is a fantastic free feature, as most viewers lose interest if the video doesn't have subtitles.

However, auto-generated subtitles on YouTube can take a few days to appear, depending on the length of your video or the audio clarity. Moreover, YouTube won't generate auto-captions if your audio isn't clear enough, the speech is in thick accents, or it's challenging to comprehend due to speech overlapping. Additionally, YouTube's auto-captions generator isn't the most accurate subtitle tool.

However, if you want to generate auto-captions on YouTube, follow these steps:

  1. Log into your YouTube account.

  2. Click your profile picture and select YouTube Studio.
    open youtube studio
  3. Open the Content section on the left to view your videos. Find the video to which you want to add captions and click the pencil icon.

How To Edit Captions and Subtitles on YouTube

As mentioned, YouTube subtitles aren't as accurate as they should be. YouTube's subtitle generator technology still needs improving because the subtitles are often poor and unintelligible. If your video has overlapping speech or thick accents, YouTube won't be able to provide accurate subtitles.

Fortunately, you can always edit YouTube's auto-captions. The process is straightforward, although manually editing incorrect subtitle lines takes time and resembles manually created subtitles. Therefore, editing YouTube's captions lines will take considerable time if you don't use another program to streamline the process.

Here's how to edit captions on YouTube videos:

  1. Go to your YouTube Studio, click Content, and select the video you want to edit.
    select a video to edit
  2. Click Subtitles in the left sidebar.
    go to the subtitles section
  3. Check if your subtitle says Automatic. Otherwise, YouTube hasn't finished auto-generating subtitles for your video. Once you see Automatic, click Duplicate and Edit.

Tips and Tricks for Editing Captions on YouTube

Editing YouTube captions can look like manually typing the subtitles yourself. It can be tedious, but it helps ensure your viewers can follow and understand your video. Therefore, we've prepared several tips to help you edit your YouTube captions for the best possible results.

First, ensure all your lines have a maximum of 32 characters. Any characters exceeding that limit won't show on the screen.

Additionally, the subtitles must be grammatically correct. Grammatical correctness always comes before the character count.

Furthermore, you can use the Scrubber tool if you need help with the time placement of caption frames. You can find it below the video to help you with minor changes in timestamps for your caption lines. If you need to add another caption frame, click the +Caption icon.

Lastly, if your video has pauses in speech, you can add a break in the captions to express it. Simply pause your video at the time of the speech break. Then, place your cursor where the speech break is in the captions line, and hit Enter to break the text into two lines. That will create a subtitle break to imitate the speech more precisely.
