What a .vtt file is
WebVTT is the standard track format for the HTML5 <track> element, so it is what browsers, YouTube and streaming players expect. It looks much like SRT — timecodes plus text — but starts with a WEBVTT line, uses dots rather than commas in timestamps, and supports positioning and CSS styling. Converting between VTT and SRT is trivial and dozens of tools do it.
Converting it
A .vtt file is commonly converted to .srt, .ass or .txt. It is a plain text format, so any text editor can open and edit it directly.
