Mode

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.

Channel

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 uppercase (alternative charset)

Changes all letters in the output file to UPPERCASE.

Double Control Codes

Control Codes are duplicated for ensure correct transmission.

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: This option is available only when the project is configured for 23.976fps. Whether it's 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 Extended Character Set

Enables the use of characters from the Line 21 extended character list set.

Appropriate error message will be displayed on export if there were extended characters but the option wasn't switched on.

Blank between pop-ons

Blank between pop-ons serve the same purpose as min. interval between subtitles. 2 frames is the default value.

Append captions to existing file

EZTitles can merge only one channel per field - CC1 or CC2 in Field 1 and CC3 or CC4 in Field 2. For example, the original .ult file already contains captions on CC1 in field 1 and the editor wants to add another captions stream to CC3.

But if EZTitles detects there are captions on both CC1 and CC2 it, by default, will: keep the existing on CC1 captions ; remove the existing on CC2 captions and add new captions to CC3. The default behavior can be modified, so please let us know via e-mail to support@eztitles.com if it's necessary to change it.

Export Zero Subtitle

Adds the Zero Subtitle to the exported file.
