How to open an SRT file.

Open the SRT as text.

Reading the file does not require the video. You should see numbered caption blocks, timecodes, and words. Keep the original file unchanged if you only want to inspect it.

These steps use SRT's plain-text structure and Apple's TextEdit document-opening workflow. Menu wording may vary by app version and system language.

Try opening a small sample.

Download this three-caption practice file, open it with your text editor, and compare it with the preview below. It contains illustrative text and timing, with no accompanying video.

1
00:00:00,500 --> 00:00:02,500
This is a sample subtitle file.

2
00:00:03,000 --> 00:00:05,500
Open it as text to read these lines.

3
00:00:06,000 --> 00:00:08,500
A real subtitle file needs its matching video.

If you see these words and timecodes, your text editor is reading the file correctly. Caption numbers and the arrows are expected; they tell a player when to show each line.

Load the SRT with a video in VLC.

To watch real captions, you need the video that the SRT was made for. Opening only the subtitle file cannot play the footage or audio. Use a local video you own or have permission to use.

1. Open the video in VLC. On Windows or Linux, use Media → Open File. On Mac, use File → Open File.
2. Add the subtitle file. Choose Subtitle → Add Subtitle File on Windows or Linux. On Mac, look under Subtitles → Add Subtitle File. Select the matching .srt.
3. Check the subtitle track. If captions stay hidden, use the subtitle menu's track selector to choose the loaded track instead of Disable.
4. Play past the first cue's start time. A file whose first caption begins at five seconds will show no text before that point.

See VLC's supported subtitle formats, its Windows menu reference, and the University of Texas SRT playback walkthrough, which shows the Mac menu names.

Loading a track in VLC displays captions during playback. To make a new video with the words permanently visible, follow the separate guide to importing SRT into an editor and exporting subtitles.

If the file will not open as expected.

A double-click opens the wrong app

Open the text editor or video player first and select the file from within that app. You do not need to change your default app just to open one file.

The filename ends in .srt.txt or .srt.rtf

Check the full filename. If an editor added .txt to an otherwise valid plain-text SRT, preserve a backup and correct the extra extension on a copy. An RTF document must be saved as plain text first; renaming it alone will not remove its formatting. TextEdit's Open and Save settings include an option to append .txt to plain-text files.

The characters look garbled

The app may be using the wrong character encoding. In TextEdit's open dialog, choose Show Options → Plain Text Encoding and select the file's encoding. Instranscript exports use UTF-8. See Apple's encoding instructions before resaving the file.

The text opens, but VLC shows no captions

Check that a video is open, the correct SRT is loaded, its track is enabled, and playback has reached a cue time. Confirm that the file contains numbered captions with start and end times, rather than a plain transcript saved under a different extension.

The captions appear, but do not match the speech

The file has opened; now check that it belongs to the same cut and playback speed as the video. For corrections, continue to the subtitle timing guide.

Before editing captions, save a backup. Keep the file as plain text with its .srt extension, preserve the timecode lines and blank lines between blocks, and reopen the saved copy to check it.
