How to Add Subtitles to a YouTube Video That Is Not Yours

A common question is: can you add subtitles to a YouTube video that isn’t yours?

Yes, if the channel owner has enabled community contributions. You can submit subtitles, and the owner can approve them.

No, if community contributions are disabled. In this case, you cannot upload subtitles directly to the video. However, you can still:

  • Create your own subtitle file and watch with a media player like VLC.
  • Use third-party tools to overlay subtitles for personal use.

In short, if it's your video, you can freely upload or auto-generate captions. If it's not yours, your options depend on whether the uploader has enabled community subtitles.
