Adding subtitles, or closed captions, to your own YouTube videos can help make them more accessible to a wider audience.
And whether you're using the Classic or Beta versions of the studio, you should be able to get it done fairly easily. Just keep in mind that the method you use will determine how long it takes to add the captions, or subtitles, to your video.
Here's how to do it using either a pre-written file or adding them as you go:
How to add subtitles on YouTube by uploading a pre-written file
Before you get started, check that the file type you want to upload is supported on YouTube.

3. Click on the title or thumbnail of the video you want to add subtitles to.
4. Select "Advanced" toward the top of the screen.
5. Under "Original video language, subtitles and CC," select a language in the dropdown, then click "Upload Subtitles/CC."

How to add subtitles on YouTube by uploading them manually
Keep in mind that this is only currently available on YouTube Studio Classic, so if you're using YouTube Studio Beta, you'll have to switch back to do this.
To do so, click the icon that looks like a figure exiting a room, located in the bottom left corner of the screen. After that, here's how to add your subtitles or closed captions:
1. Go to your video manager.
2. Select the video you want to edit.
3. In the top toolbar, click "Subtitles/CC."
4. Choose the language of the subtitles and click "Set Language."
5. Click "Add New Subtitles or CC," and select the language in the dropdown.
6. Choose "Create New Subtitles or CC."
7. Play the video and pause wherever you want to add a subtitle or closed caption.
8. Type the subtitles or closed captions into the text box to the left of the video and click the blue "+" button.
9. In the section below the video, you can drag the new caption or subtitle to adjust when, and how long, it will appear on the screen.
10. Repeat as necessary, and when finished, click "Publish" or "Save Changes."
