Reference

What each dialect looks like, and what a conversion cannot carry across.

Timestamp forms accepted on input

Format	Form	Note
LRC	`[mm:ss.xx]`	Canonical; xx is hundredths
LRC	`[mm:ss.x]`	One digit is tenths, not hundredths
LRC	`[mm:ss.xxx]`	Milliseconds; NetEase, QQ, Kugou
LRC	`[mm:ss:xx]`	Colon fraction; older Chinese files
LRC	`[hh:mm:ss.xx]`	Non-standard, usually a converter artefact
SRT	`HH:MM:SS,mmm`	Comma is canonical; a period is accepted
VTT	`[HH:]MM:SS.mmm`	Hours optional; period only in valid WebVTT

Word timing differs between A2 and WebVTT

Enhanced LRC repeats the line timestamp on the first word; WebVTT omits it, because the first segment inherits the cue start. WebVTT also requires each cue timestamp to increase and to stay inside the cue, so out-of-order input is clamped and reported above.

The bracket tag is not a subtitle construct

A leading [SKIP] or [NOTE] is a MUSA Player application tag carried inside the cue body. Any other player shows it on screen as ordinary text. It also collides with SDH sound cues such as [door creaks] and with section labels such as [Chorus], so turn the reading option off for subtitle work.

Encoding

This tool reads and writes UTF-8 only. WebVTT mandates UTF-8; LRC and SRT declare no encoding at all, so a legacy Big5, GBK or Windows-1252 file will arrive as mojibake. Re-save it as UTF-8 first.
