EIA 608 closed captions for MPEG-2 streams can be encoded with 4 channels of alternate
languages these include CC1,CC2, CC3, and CC4 data respectively.
EIA 708 closed captions for MPEG-2 streams can be encoded with 6 channels of alternate
languages these include Service numbers 1,2,3,4,5,6. Because MacCaption has the world’s first
true 708 authoring software engineering it can include text style and opacity options as well as
Unicode Asian language settings in the encoding process.
In order to include multiple alternate languages in your encode please populate programs A
through F in your MacCaption project. These can be assigned to different closed caption
channels in the top menu Caption>Encode Preferences.
MacCaption can currently encode closed captions for the following MPEG formats:
DVD Closed Captions (*.m2v)
DVD Style Closed Captions (*.mpg)
ATSC DTV 608/708 Closed Captions (*.mpg)
CCube/LSI DVx 608 Linear Closed Captions (*.mpg)
CCube/LSI DVx 608 Temporal Closed Captions (*.mpg)
Sigma MPEG-2 line-21 720x512 (*.mpg)
MPEG-2 Video Codecs
If you do not have a good Mpeg codec on your computer, you may consider Main Concept
MPEG codec. The codec works well for MacCaption. You may get this codec from

HD Tapes
Panasonic DVCPRO HD
Captions can be added to DVCPRO HD QuickTime files. You need to use FireWire to send the
captioned video to a compatible VTR such as a Panasonic AJ-HD1400. This FireWire operation
must be done from MacCaption, and does not work with Final Cut Pro Studio 2. In addition,
MacCaption can capture DVCPRO HD video content from FireWire and decode the caption data
from it.
DVCPRO HD video content can contain both 608 and 708 caption data and so the process for
encoding closed captions to DVCPRO HD should be set for both 608/708. To ensure that the
encoding includes both 608/708 go to top menu Caption>Encode Preferences and enable both
608 and 708 options for encoding to DTV.
