About MCC Files
MCC files contain the raw VANC packet data (CDP’s, caption data packets) for a
segment of video. The raw data contains 608 and 708 captions and service information (CSD’s,
caption service descriptors). MCC files are created using CPC MacCaption, CPC CaptionMaker,
and possibly other software.
What makes MCC files different from all the other caption file formats that the HDE3000
can encode is that they contain 708 caption data. All the other file formats that the HDE3000
can encode only contain 608 caption data (the HDE3000 “transcodes” the 608 to 708).
Encoding MCC files with the HDE3000
The HDE3000 menus have not changed, but you may now select MCC files for encoding
just like all the other caption file formats that the HDE3000 supports (Cheetah *.cap, Ultech *.ult,
etc.).
When the HDE3000 encodes an MCC file, it directly inserts the 608 data, 708 data, and
service information contained in the MCC file, overwriting any existing caption data and service
information. Because of this, it cannot multiplex when encoding MCC files (it cannot add a
service of captions while preserving existing services).
Important!
• An MCC file is generated for the particular frame rate of the video it is to be encoded
into. If the frame rate of the video and the frame rate of the MCC file do not match then
the caption data will not be encoded properly.
• When encoding an MCC file, the HDE3000 cannot multiplex (add a service of captions
while preserving existing services).
• When encoding an MCC file, the HDE3000 cannot perform weather lift (weather lift is
automatically disabled when encoding an MCC file).
• When encoding an MCC file, the HDE3000 will only encode one CDP per frame of video
(in field one only, no VANC data will be encoded into field 2).
• Since MCC files contain 708 data, the transcoders in the HDE3000 are disabled when it
is encoding an MCC file.
