What is a .SRT file?
SRT (SubRip) is the most common subtitle format - a simple text file of timed captions. Read by VLC and virtually every media player.
- Did you know
- The SRT format comes from the SubRip subtitle-ripping tool released around 2000.
- Each SRT entry has a fixed shape: a sequential number, a start and end timecode joined by an arrow, then the caption text and a blank line.
- SRT timecodes use a comma before the milliseconds (00:01:23,456), a quirk that distinguishes them from the full stop used by many other formats.
- The base format carries no styling, but players often honour a handful of inline HTML tags such as bold and italic embedded in the caption text.
- A .SRT 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 .SRT file
- Drag a .SRT 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.
