About VTT
VTT (Web Video Text Tracks) was specified by the W3C in 2012 as the standard for web subtitles and is the modern successor to SRT with significantly extended capabilities. VTT extends SRT with CSS styling options, percentage-based positioning, ruby annotations for Asian languages, and vertical writing direction for traditional Japanese and Chinese text. The header must begin with WEBVTT, followed by optional metadata. Timestamps use the format HH:MM:SS.mmm with a period instead of a comma. VTT supports cue identifiers, chapter markers, metadata tracks, and language tags for multilingual subtitles. All modern browsers support VTT natively via the HTML5 track element. YouTube and Vimeo use VTT as their standard subtitle format for their web players. Converting from SRT to VTT is straightforward - usually just changing the timestamp format and adding the WEBVTT header. VTT also supports region definitions for complex positioning and is the recommended W3C standard for HTML5 video subtitles.
About SRT
SRT (SubRip Subtitle) was developed around 2000 in connection with the SubRip DVD ripping program and is the simplest and most widely used subtitle format worldwide. An SRT file contains sequentially numbered entries with timestamps for start and end in HH:MM:SS,MMM format and the subtitle text below. SRT does not support formatting, positioning, or styling information - it is pure text with timing data. This simplicity makes SRT universally compatible: virtually every video player, streaming platform, and editing program reads SRT files without issues. WebVTT is the modern successor with CSS styling support that is increasingly displacing SRT. However, SRT remains the de facto standard for subtitles since it can be read by any software without parsing problems. SRT files can be edited with any plain text editor, making the correction and creation of subtitles extremely simple and accessible. For more complex layouts, converting to VTT is recommended.
