New Captioning in Flash Component

WGBH’s National Center for Accessible Media (NCAM) is providing a new component that allows Flash developers to add captions to video in Flash. “cc for Flash” is a free download and is available at the NCAM web site ( This component helps developers use captions in QuickTime’s QTtext format or in the new W3C Timed Text format called DFXP.
MAGpie's export menu, showing the DFXP output option.
Also announced is an update to MAGpie, NCAM’s free closed captioning tool. This update adds a new export item to MAGpie’s export menu to allow for the output of DFXP caption files.
To use MAGpie to caption an FLV, you’ll need to use a file in a media type that is supported by QuickTime, so if your video starts out as an MPG or MOV just use that for the captioning, and then use the XML file generated by MAGpie. It won’t matter as long as the timeline for the FLV is the same as the timeline for the original video. If you create the FLV from a portion of a larger file you’ll want to get a QT-compatible file that has the same timeline for the captioning.
I’m really excited about this new development – send links to captioned video if you use cc for Flash. Thanks to NCAM for the great work!
