In the fourth season of ‘Bruce’s Shorts’, Bruce Devlin takes a look at the Interoperable Master Format (IMF). IMF needs a generic captioning and subtitling format for the planet. Episode 5 asks “Why choose IMSC1?”
Internet Media Subtitling & Captions (IMSC1) profile of Timed-Text Markup Language (TTML), the first global standard for captions. IMSC cations can be rendered into different formats for delivery: CTA 608, CTA 708, WST and many others. IMSC is designed to be used for mastering to multiple standards, just like IMF.
