Then preview the final video with subtitles and edit the text once again if there is any mistake that you can spot. You can also change the timing by editing the timestamps.

After you're done, check the subtitles and match them with your video.

Type Manually: With this option, you can manually type the subtitles as you watch the video.

Auto-Sync: You can copy your captions and paste them and YouTube will auto-sync them according to your video.

But, if you have text that needs to be synced with what you are saying in the video, then you can choose the Without timing option, YouTube will automatically sync the subtitles according to your video.

Upload File: If you have a file that has the exact script used in the video, you can choose the With timing option.

Click Add under that, and you will get three options - Upload File, Auto-Sync, and Type Manually. When you come to Video Elements, you will see the option of Add Subtitles. During the upload process, you will be taken through various sections like Details, Rights Management, etc.

Click the Upload Videos icon, and start uploading your video. Open YouTube Studio and log into your channel.

You cannot add subtitles to your videos using the YouTube Studio app on mobile, so you will have to do it on your desktop.
