Getting a Caption File for Your Video

Videos display closed captions by referring to an accompanying caption file, which contains text of speech and sounds with corresponding timestamps. 

Caption files come in many different formats. The following common formats are compatible with YouTube, although some features such as styling or placement may be lost:

  • SRT (.srt)
  • SBV (.sbv or .sub)
  • WebVTT (.vtt)
  • TTML ( .ttml)
  • SCC (.scc)
  • EBU-STL (.stl)
  • Videotron Lambda (.cap)
  • Cheetah (.cap or .asc)
  • DFXP (.dfxp)
