The National Center for Accessible Media at WGBH (NCAM) announces the launch of CADET (Caption and Description Editing Tool).
 CADET implements all of the basic features necessary to create high-quality captions, plus many of the functions available only in high-end caption-authoring workstations. CADET allows users to . . .
o   create captions for video formats that play natively in browsers (e.g., mp4, m4v);
o   import plain-text transcripts for editing and timing;
o   transcribe caption text directly into the caption editor;
o   edit, style and time captions;
o   import existing caption files (WebVTT, SRT, TTML, QTText) for clean-up, editing or re-timing;
o   export caption files in common formats, including WebVTT, SRT, TTML, QTText and SAMI, as well as plain-text scripts.
CADET is free, downloadable caption-authoring software that enables anyone to produce high-quality caption files that are compatible with any media player that supports the display of captions. CADET can also be used to generate audio-description scripts. CADET does not require an internet connection in order to operate: it runs locally in any Web browser, so users do not need to upload private videos or proprietary content to servers or video-hosting sites in order to create captions.
NCAM is providing this tool to all users free of charge.  Please follow the link below to download your copy of CADET now.  And please join our online community forum to share your feedback.
