SRT vs VTT: Which Subtitle Format Should You Use

SRT and WebVTT are both timed caption formats. Here is the real difference, when each one matters, and how to get either from your media with LiteScribe.

SRT and WebVTT (VTT) are both timed subtitle formats. SRT is the universal default with numbered cues and comma-millisecond timestamps; VTT is the web standard with a WEBVTT header, period-millisecond timestamps, and optional styling. LiteScribe exports SRT directly, and the free in-browser converter turns that SRT into VTT when a web player needs it. Free to start.

The core differences

Both formats do the same job: pair lines of text with start and end timestamps so captions appear on cue. The differences are in the details. SRT (SubRip) numbers each cue and writes timestamps with a comma before the milliseconds, like 00:00:01,000 --> 00:00:04,500. WebVTT (Web Video Text Tracks) opens with a WEBVTT header line, drops the cue numbers as optional, and uses a period before the milliseconds, like 00:00:01.000 --> 00:00:04.500. VTT can also carry cue settings for position and a basic styling block, which SRT cannot.

In practice the timing and text are the same in both; the comma-versus-period and the header are the markers that tell tools which format they are reading. Converting between them is a mechanical transform that keeps the timing intact, which is exactly what the free subtitle converter does in the browser.

When to use SRT

Use SRT when you want maximum compatibility. Video editors, desktop media players, and most upload forms accept SRT, so it is the safe default and the format to reach for when you are not sure what a tool wants. It is also the easiest to hand-edit because it is the plainest. LiteScribe exports SRT directly from any transcript, so this is the format you get out of the box.

When to use VTT

Use WebVTT when you are working with web video. The HTML5 <track> element expects VTT, so captions delivered through a website or web player are usually VTT. If your destination is a browser-based player rather than an editor, VTT is the native choice. The path with LiteScribe is to export an SRT and then convert it to VTT with the free subtitle converter, which adds the WEBVTT header and switches the millisecond separator to a period while preserving every timestamp.

How LiteScribe fits in

LiteScribe generates subtitles by transcribing your audio or video and exporting an SRT aligned to the speech. Because SRT is the universal format, that single export covers the widest range of tools. When your target is a web player that wants VTT, run the exported SRT through the free converter at the subtitle converter tool, which produces a valid WebVTT file entirely in your browser with no upload. If the captions need a timing nudge, the free timing shifter handles that too. One transcription, then convert and retime as each destination requires.
