- IMSC: subtitles and captioning for the Web
-
IMSC (TTML Profiles for Internet Media Subtitles and Captions) is a file format for representing subtitles and captions. It uses XML to describe content, timing, layout, and styling. IMSC is very similar to HTML and CSS in concept — in fact, most IMSC styles have a direct equivalent in CSS.
