Summary
Add subtitles in YouTube Studio by opening the video's Subtitles page, choosing a language, and then uploading a caption file, typing captions manually, or pasting a transcript to auto-sync. YouTube also creates automatic captions for many videos, which you can review and edit.
Step by step
- Sign in to YouTube Studio.
- Select Subtitles from the left menu and pick your video.
- Add a language if needed, then click Add under subtitles.
- Choose Upload file, Auto-sync or Type manually.
- Publish when you are done.
Caption file formats
YouTube accepts common caption formats such as .srt and .vtt. See YouTube Help for the full supported list.
Why bother
Captions make videos accessible to deaf and hard-of-hearing viewers and to anyone watching with the sound off.
