MCC captions format is designed by CPC (Computer Prompting & Captioning Co.) to contain both CEA-608 data for NTSC standard definition video (29.97fps) and CEA-708 data for Digital Television.
The captions data is rendered according to CEA-708.1 standard which allows encoding 3D information with the caption services. As 3D is not supported by legacy CEA-608 captions the export options are limited to export only CEA-708 compliant captions.
When you click the MCC CEA-708 export, the following dialog will appear:
Scipt Info
Version |
Here you need to select the version of the output file. The main differences are: MCC v. 1.0 - supports 24, 25, 30, 30 DF, 50, 60 frame rates. MCC v. 2.0 - also includes support for 60 DF (59.94fps). |

Type |
The CEA-708.1 standard supports 3D captions, 3D captions are not supported by the CEA-608, and for this reason the export option is limited to export only CEA-708 compliant captions. |
Write empty frames |
Empty packets are inserted for the frames that contain no captions data. The exported file will contain packets for every video frame. |
Compact Packages |
According to the MCC specification a simple character compression could be applied. |
