Closed Caption File Format Guide for Netflix
Netflix
Netflix has two recommended formats. The EMA Closed Captions Working Group has identified Scenarist (.scc) as a preferred format due to its status as the de facto standard for CEA-608 and CEA-708 data. SMPTE-TT is also recommended as, under the applicable laws, it is considered safe if captions are compliant.
Compatible formats:
SubRip (.srt)
Scenarist (.scc)
Timed Text (.ttml)
DXFP (.dxfp)
WebVTT (.vtt)
Cheetah CAP (.cap)
MacCaption (.mcc)
Quicktime Subtitle (.qt.txt)
