What is a VTT file?
A VTT file is a text file saved in the Web Video Text Tracks (WebVTT) format. It contains supplementary information about a web video, including subtitles, captions, descriptions, chapters, and metadata. VTT files do not contain any video data.
Most online video hosting services, such as YouTube and Vimeo, allow users to caption or subtitle their videos using VTT files, as do media players like VideoLAN VLC Media Player. Additionally, the WebVTT format is designed to provide:
- Chapters for content navigation
- Text video descriptions
- Other metadata aligned with audio or video content
NOTE: WebVTT replaced the Web Subtitle Resource Tracks (WebSRT) format in 2010.
How to open a VTT file
You can open and edit a VTT file using any text editor, such as Microsoft Notepad (Windows), Apple TextEdit (Mac), or GitHub Atom (multiplatform). You can also view a VTT file's contents by dragging the file into any web browser.
If you'd like to use a VTT file as a subtitle track in VideoLAN VLC Media Player:
- Begin playing the video you want to use your VTT file with.
- From the VLC Media Player menu bar, select Subtitles → Add Subtitle File ....
- Navigate to the folder containing your VTT file, select the file, and then select Open.
How to validate that VTT subtitles are formatted correctly
You can validate that the subtitles a VTT file contains are formatted correctly by uploading the file to the Subtitle Validator available at https://validator.subtitledpro.com/.
How to convert a VTT file
Many free online conversion tools allow you to convert VTT subtitles to the .SRT subtitle format, which more media players support. For example, the tools at https://www.happyscribe.com/subtitle-tools/convert-vtt-to-srt and https://www.veed.io/subtitle-tools/edit allow you to convert VTT files to SRT files.
