WebVTT

• Extensions: .vtt

WebVTT is a subtitle format for use on websites along HTML5 videos. It is bases on SubRip and isn't very different from it. Basically you can convert any .SRT to .VTT by adding a line with "WEBVTT" before it. You should however strip all formatting since formatting used by WebVTT is not fully compatible with SubRip.
