Import/Export Closed Captions

Import Closed Captions files

The import procedure is similar to the one described earlier. Use File/Import... menu or toolbar button.

Standard Windows open dialog is displayed containing files in all supported by EZTitles formats. There is "Append" check box at the bottom of the dialog which you can select if you want to append the imported file to the current subtitles.

Importing of some Closed Captions dedicated formats (CIN, SCC, NCI CAP, ULT, TDS, ProCAP, FLC - NCI Roll-Up captions) will display additional option when the project is configured for 23.976fps:

Interleave CC data for 23.976fps video to maintain 30/1.001 pairs per second - changes how caption's timings are calculated for 23.976fps in accordance with the CEA-708-B standard.

When the option is turned on, 3 pairs of CC data will be encoded for every other frame. And when it's turned off - 2 pairs of CC data will be encoded for every video frame. Or in other words, turning the option on allows 25% more text to be decoded over the same period of time which also accounts for decreasing the "time to process" required for each caption.

Note: Whether the option is clicked on or off by default depends on how the same option is configured at the Project Settings/Safe Area menu. We don't recommend turning the option on when it isn't turned on in the Project Settings. And vise-versa.

Export Closed Captions files

When the Export command is selected from the File/Export menu or toolbar button, the following dialog box appears:

 Export Closed Captions files


Export Closed Captions files

 

Here you can choose the format into which you wish to export the current file. Then you have to click the Export button to proceed.

Depending on the type of the captions file you wish to export to, you will be asked to adjust some of the followig settings:

 Closed Captions Export Configuration


Closed Captions Export Configuration

 

With the Mode section you can choose to prepare the subtitles for the Closed Captions CEA 608, TeleCap I or TeleCap II modes. Differences between these modes are described in the Project Settings section.

Depending on your choice for Channel, the prepared subtitle file will be inserted in one of the four data channels associated with Closed Captions: CC1 and CC2 in Field 1, CC3 and CC4 in Field 4.

Export in upper case will output a file which text contains only UPPER case letters.

Double control codes - the control characters are duplicated to ensure correct transmission.

Export extended character set -  enables the use of characters from the Line 21 extended character list set. If not selected and there are extended characters in the captions you will receive an error message.

Blank between pop-ons - the default value is 2 frames.

Interleave CC data for 23.976fps video to maintain 30/1.001 pairs per second - changes how caption's timings are calculated for 23.976fps videos in accordance with the CEA-708-B standard. The option is available when exporting into the following file formats: CIN, SCC, NCI CAP, ULT, TDS, ProCAP,  MCC and FLC - NCI Roll-Up captions.

When the option is turned on, 3 pairs of CC data will be encoded for every other frame. And when it's turned off - 2 pairs of CC data will be encoded for every video frame. Or in other words, turning the option on allows 25% more text to be encoded over the same period of time which also accounts for decreasing the "time to process" required for each caption.

Note: Whether the option is clicked on or off by default depends on how the same option is configured at the Project Settings/Safe Area menu. We don't recommend turning the option on when it isn't turned on in the Project Settings. And vise-versa.

For SCC formatted captions additional options will appear:

QuickTime compatible SCC - the output caption file could be played under Mac OS via QuickTime player with ClosedCaptionImporter filter installed. Please note, that if you are producing 23.976fps SCC files, you shall make sure that either 30fps Drop or Non-Drop has been selected from the TimeCode Format drop-down.

Custom Frame Separator - enables you to specify custom symbol to separate frames from seconds of the timecode in the output file. Colon (:) is used as the default symbol.

Erase Display Memory with start of programme - Enables insertion of Erase Display Memory (EDM) control code with the first video frame of the program. This may be needed by certain equipment and applications, like QuickTime, to correctly keep Closed Captions data in sync with the video playback.

Manual

Enables you to manually type in EDM's timecode.

Auto

Automatically sets the Programme Start timecode using the first subtitle's In-cue rounded down to the closes hour. For example, if the first subtitle starts at 10:00:32:21 EDM's value will be automatically set to 10:00:00:00.

Programme Start TC

Automatically uses the value of the Programme Start TimeCode parameter saved in the Details. Programme Start TC can be selected from Video/Setup Timecode with a video opened in.

Video Start TC

Automatically gets video's start time as specified in Video/Setup Timecode. This option can be used only when a video is loaded in.

The user can create list with  the"favorite", most frequently used, formats for import or export by clicking the bullet on the right side of each particular format. To remove any of them from the favorites category it's only necessary to click on the bullet again.

EZTitles does also provide unique function that allows you to select how many and which subtitles will be saved to the exported file by using the options that will show up after pressing the Range button.
