关于这种格式

WebVTT — the subtitle standard for HTML5 video. Almost the same as srt, but browsers read it directly and it carries a little position and style.

能承载的内容

• Lines and timings
• Position and alignment
• Simple styling (CSS)

无法承载的内容

• Player support — old desktop players know only srt

转换为其他格式时

打不开的时候

• Old players — convert to srt
• Missing WEBVTT header — it must be the first line

一句话 Subtitles for a web page: vtt. Anywhere else: srt.
