 Raw Captions With Time (RCWT) is a format native to ccextractor, a commonly
-used open source tool for processing 608/708 closed caption (CC) sources.
-It can be used to archive the original, raw CC bitstream and to produce
-a source file for later CC processing or conversion. As a result,
-it also allows for interopability with ccextractor for processing CC data
-extracted via ffmpeg. The format is simple to parse and can be used
-to retain all lines and variants of CC.

 been stable and unchanged for 10 years as of this writing.
