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".
1. 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 sub-track and select a subtitle track.
Picture 68 of How to Embed Subtitles in Videos
Save the document as an SRT file. Use the following steps to save the text document as an SRT file. Once the file is saved, move to the Testing Your Subtitles method to learn how to test them out.
1. 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.
2. Mac: Click Save to save the file as a ".rtf" file. Use the Finder to navigate to the location of the document and click it to select it. Click File and then Rename. Deleted 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.

Here is an example of subtitle text properly formatted in an SRT file:
