How to Embed Subtitles in Videos

Last Updated: July 2, 2021 Tested

Video subtitles are useful for displaying dialogue and sounds as on-screen text for people who are hard-of-hearing or for language translation. If you're using YouTube, you can easily upload an existing subtitle file (usually in the SRT format) or type your own subtitles by hand. If you want to add subtitles to a video file on your computer, you can create an SRT file and add it to your video with HandBrake. This wikiHow teaches you how to add subtitles to a YouTube video, as well as a video on your PC or Mac.

Type --> immediately after the starting time. Typing two dashes and an arrow separates the starting time and the ending time for the subtitle.
5
Type the ending time for the subtitle. This is the time when the subtitle stops displaying. The ending time should be in "[hour]:[minutes]:[seconds],[milliseconds]" format. The entire line containing the subtitle time stamp should look something like this 00:00:01,000 --> 00:00:05,040.

Press ↵ Enter or ⏎ Return twice. After you finish typing the subtitle, press the Enter key twice to create line-space between the subtitle you just made and the next subtitle. Repeat these steps for each subtitle in the video.
9
Repeat these steps for each subtitle in the video.
10
Click File and then click Save As. After you finish typing your subtitles, you'll need to save the file as a ".srt" file.
- In TextEdit on Mac, click Save instead of "Save as".
11
Navigate to the folder containing the video. You should save the SRT file in the same folder as the video that the subtitles correspond to.
12
Give the text document the same file name as the video. Use the box next to "Filename" in Windows, or "Save As" on Mac to type a name for the SRT document. Both the video and the SRT file should have the same filename. If the file name for the video is "Introduction.mp4", the SRT file should be titled "Introduction.srt".
- Using VLC, you can test the subtitles if the SRT file is saved to the same location and has the same filename as the video file. Click Subtitles and then select a subtitle track.
13
Save the document as an SRT file. Here's how:
- Windows: While saving the file in Notepad, delete the ".txt" extension at the end of the file name and replace it with ".srt". Then click Save.
- Mac: Click Save to save the file as a ".rtf" file. Use Finder to navigate to the location of the file and click it once to select it. Click File and then Rename. Delete the ".rtf" extension at the end of the file name and replace it with ".srt". Click Use .srt when asked if you want to keep the extension.
