user has a copy of any of the 3 Manzanita Multiplexers installed in their Applications folder in
OS X, the “Generate a Transport Stream using Manzanita software” option will be enabled when
they select File>Export>ATSC DTV 608/708 Closed Caption (to MPEG-2) file option.
Before beginning this operation, make sure that a “Scratch Folder” for MacCaption is selected
for the demux and remux operation. To set a “Scratch Folder” go to top menu
MacCaption>Preferences. In the Preference window select the General tab and press the Scratch
Disk option to set your scratch disk location. If possible, set the scratch disk to a raid or
secondary hard drive location on your Mac.
Also, the user must set the proper encoding settings for both 608/708 closed caption data
insertion. We recommend that both 608 and 708 data be added to both Standard Definition
MPEG-2 material as well as High Definition MPEG-2 streams. To ensure that both 608 and 708
is encoded into your transport stream follow the directions below:
Go to top menu Caption>Encode Preferences
In the Encode Preferences window make sure that program A is set to CC1 for 608 Encode
Targets, and Program A is set to “1” for 708 Encode Service Number Targets.
Enable the checkboxes that say Include 608 captions in DTV export operations and 708 captions
in DTV export operations.
Click OK.
Once these settings are enabled you are ready to encode your transport stream with closed
captions. Follow the directions below to add captions to a transport stream with MacCaption.
1. Select File>Export>ATSC DTV 608/708 Closed Caption (to MPEG-2) file option
2. Save the output TS (transport stream) file on your desktop
3. Select the “Generate a transport Stream using Manzanita software” option
4. Press the button “Configure”
5. You must specify the Video ID and Audio ID of your input Transport Stream. If you
know you are encoding for CableLabs set and enable “Use Video ID” to 481 and set and
enable “Use Audio ID” to 482. If you do not know the Video ID or Audio ID of your
transport stream please download MPEG Streamclip from www.squared5.com or
purchase Manzanita MPEG ID to find the correct parameters.
6. If you have a Manzanita configuration file it can be applied by selecting “Encode using
user specified Manzanita cofig file” and clicking “Choose”. This feature is optional and
if left disabled, Manzanita multiplexer will use the default CableLabs configuration for
the multiplexing.
7. Press OK and then press Save
8. Finally, select the input file located in your hard drive. This last step will commence the
encoding and multiplexing of your transport stream. Please allow some time for this
process to complete.
