What happens when converting VTT to SRT?

WebVTT content is parsed into a unified millisecond timeline before being exported as SubRip Subtitle. Valid timing and subtitle text are preserved.

SRT output creates numbered subtitle blocks and uses comma-separated millisecond timestamps.

Empty subtitles are removed and valid cues are sorted by start and end time.

Source file format

VTT · WebVTT

VTT, or WebVTT, is a timed-text format designed for web video. HTML5 video elements can use it through track elements for subtitles, captions, chapters, and other synchronized text.

File structure: A WebVTT file normally begins with a WEBVTT header and uses a dot as the millisecond separator. It may also contain cue identifiers, positioning settings, comments, and metadata.
Common uses: VTT is commonly used by web players, online courses, recorded streams, accessible closed captions, and videos that need subtitles displayed directly by modern browsers.
Conversion notes: VTT supports richer web-caption features than SRT. Cue positioning, voice tags, chapters, and some metadata may not survive conversion to simpler formats.

Target file format

SRT · SubRip Subtitle

SRT, short for SubRip Subtitle, is a simple, open, and highly compatible text subtitle format. It is one of the most common interchange formats used by video players, editors, and online video platforms.

File structure: An SRT file contains sequentially numbered cue blocks. Each block has an index, a start and end timestamp separated by an arrow, and one or more lines of subtitle text. Milliseconds normally use a comma separator.
Common uses: SRT is commonly used for movies, video editing imports and exports, online video uploads, and exchanging subtitle timing and text between applications.
Conversion notes: SRT primarily stores text and timing. It is not designed for complex positioning, typography, or animation, so advanced ASS or SSA styling is normally lost when converting to SRT.
