If you are about to add subtitles to a long video interview, public speech, or a movie, manually adding subtitles to a video would be far time-consuming.

Interestingly, not only can you directly upload your clips from the local computer, but also paste a URL to add subtitles to an online video like your YouTube video.
Then Kapwing will use AI to automatically process the video and generate subtitles for different time slots.
Since auto-generated subtitles can't be 100% accurate when it comes to slang, accents or names, etc. So, you need to playback the video from beginning to the end and correct the wrong subtitles manually.
You can directly download the video with subtitles in MP4 format locally. However, if your video is more than 7 mins, you need to upgrade to Kapwing Pro subscription for the free download.
How to Add Subtitles to an Uploaded YouTube Video
Apart from online video editors like FlexClip or Kapwing, if your videos have already been published to YouTube, you can use YouTube Studio to directly add subtitles to online YouTube videos, which is completely free.
