What is a .VTT file?
WebVTT (VTT) is the web-standard subtitle format used by HTML5 video.
- Did you know
- WebVTT was created in 2010 as the captions standard for HTML5 video.
- WebVTT began life under the name WebSRT, a lightweight format inspired by the popular SubRip subtitle format rather than the heavier XML-based TTML.
- It was chosen as the caption format for the HTML5 <track> element, letting browsers show subtitles without any plug-in.
- Cue settings let each caption choose its own on-screen position and alignment, so text can be placed away from on-screen action.
- A .VTT file is plain text, so you can open and edit it in any text editor.
- What Analyser shows you
- Parse subtitle cues and timing from SubRip (SRT), WebVTT, ASS/SSA, MicroDVD and SubViewer (.sub): cue count, on-screen time, and a full timed cue list. MicroDVD frame timings are converted to time using the declared or assumed frame rate; binary VobSub .sub image subtitles are identified.
- Open a .VTT file
- Drag a .VTT file onto the Analyser home page (or tap to pick one). It opens entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
