MacCaption-HD
Matrox and CPC have co-developed an innovative solution that allows the MacCaption HD software to encode and decode HD captions to and from any HD or SD decks using the Matrox MXO2 and HD-SDI.
A new feature in the latest Matrox MXO2 1.4 drivers supports down-converting HD captions to SD line 21. Now you can simultaneously print your timeline to both HD with 708/608 captions and SD with line 21 captions. This also allows you to proof your 4VANC caption track on a regular TV with a CC decoder, instead of needing an expensive HD-SDI caption decoder. The MXO2 can also up/down/cross-convert any video format to any other format while maintaining the captions.
MPEG2 Transport, Program, and Elementary streams
MacCaption-HD ties into Manzanita’s multiplexing software to generate 708/608 closed captions in CableLabs-compliant HD MPEG-2 transport streams (requires Manzanita software to be installed separately) for tapeless delivery to networks and VOD.
MacCaption-HD (including the demo version) can also decode/retreive both 708 and 608 captions from MPEG-2 transport streams, including ATSC broadcast streams. You can verify that your stream is compliant with FCC regulations and that the 708 captions are encoded properly.
Users without Manzanita software can add captions to generic MPEG2 Elementary and Program streams. The MPEG2 can be SD or HD. Captions can be formatted in any one of the following styles: ATSC DTV 608/708, DVD, CCube/LSI DVx 608 Linear or CCube/LSI DVx 608 Temporal. SCTE20-style 608 captions can also be decoded.
Panasonic DVCPRO HD
Captions can be added to DVCPRO-HD .mov (QuickTime) files. You need to use MacCaption-HD to print the captioned video via firewire to a compatible VTR such as a Panasonic AJ-HD1400.
SONY XDCAM HD
Currently our MacCaption HD software can retrieve (decode) and encode captions from Sony XDCAM MXF files (1080i and 720p) which came from a Sony XDCAM HD deck. Compatibility with Final Cut Pro-generated MXF files and other kinds of MXF files will be available very soon.
