Editing the Text and Position of Closed Captions
If you have extracted, imported, or created closed-caption segments, you can edit them in the Closed Captioning pane using the following procedures. Make sure you select Closed Captions from the Media Pane menu to display closed captions in the Media pane.
To enter edit mode and edit closed-caption text, do one of the following:
Double-click the Text field.
Select the Text field of a closed-caption segment and press Enter.
The Text field turns white and you can type the text. Use the Italic button and the Underscore button to format the text. Click the musical note button to add a musical note. Press the Enter key to start a new line.
MediaCentral UX limits the display to four rows, with of 32 characters per row, including spaces. A space is also required before the first word in the sentence, but not at the end of a sentence. If you do not include a required space, MediaCentral UX displays a message informing you that a space is required.
If you add a blank line in a caption segment, two different captions are displayed.
If you apply formatting to two words in a closed caption (for example, an underscore), then repackage and extract the closed captions, the formatting is applied to the space between the words. This is as designed.
To save closed-caption text, do one of the following:
Press Ctrl+S. Text is saved and you remain in edit mode.
Click the Save button. Text is saved and you exit edit mode.
Press Ctrl+Enter to exit edit mode.
Use the mouse to select a different closed-caption segment.
Add a new closed-caption segment.
To position a closed caption:
1. Do one of the following:
Select a closed-caption segment and double-click in the Align box.
Select a closed-caption segment, right-click, and select Change Alignment.
Click the Align field of a closed caption segment and press Enter.
Select a closed-caption segment, click the Closed Caption Pane menu button, and select Change Alignment.
A nine-position alignment grid is displayed. Choices are top, middle, bottom, left, center, and right.
You can select multiple closed-caption segments and change the alignment for all of them with the same selection.
2. Select a position from the grid.
MediaCentral UX aligns the caption or captions according to your selection. Captions are aligned within the standard video safe area. You can view safe area grids in the Media viewer by clicking the Media Pane menu button and selecting Safe Areas. This display can help if you need to review previously positioned captions or create new ones. The following illustration shows the safe area outlines. The inner outline is the safe title area. The outer outline is the safe action area.
If closed captions were extracted or imported, and they differ from the nine available positions in MediaCentral UX, MediaCentral UX preserves the original positions. If you change the positioning in MediaCentral UX, you cannot restore the original location.
To delete a closed caption, select the closed-caption segment and do one of the following:
Press the Delete key.
Right-click and select Delete.
Click the Closed Captioning Pane menu button and select Delete.
To save closed-caption segments:
Click the Save button.
The save status message changes from “Unsaved Changes” to “All Changes Saved.”
Changes are automatically saved whenever you exit edit mode or perform other edits, such as changing alignment or deleting a closed-caption segment.
