Cablecast Caption Editor

Any completed sidecar file in the Text Tracks screen may be edited by the user. Use the Action dropdown and select Edit next to the appropriate sidecar file.

The Cablecast Caption Editor can be used to make minor or significant changes to the existing captions. Various caption attributes can be adjusted including

• Adding, Removing, and Editing text
• Caption location on the screen
• Timing of the display of the captions

Media Player Panel

The Media Player panel allows the user to move around within the playback video file associated with the caption data. The panel includes typical navigation tools you would find in a video player:

• Volume Adjustment
• Playback Speed - Select from .25 to 8 times real time playback
• Play Controls - Jump to start/end, move ahead or back by one frame, play/pause
• Timecode Window - Will display the current time position in the file. A time can be entered in this field to jump to that position.
• Caption Events - Jumps ahead or back one caption event
• Lock CC/Video - ????
• Preview CC - ????

Search and Replace Panel

The Search and Replace panel can be used to search the Events of the selected Event Group for a specific word (or regex expression), and replace it with a new word or character set.

Enter a Search term and click the search button to begin searching the currently selected Event Group. The number of results will show next to the bottom controls along with arrows to navigate between them. Use the arrow buttons to quickly jump between results. The selected Event will automatically scroll into view and the search term will be highlighted.

There are additional Search Options available to help improve search results:

• Case Sensitive - Makes the search case sensitive and removes results that do not match the term exactly. Default search is case insensitive.
• Match Whole Word - Match the entire word based on word bounds. For example searching the word to with match whole word enabled will return results for the word to but not too or tomorrow.
• Replace All - When replace all is enabled, the replace button will affect all search results.
• Regular Expression - Enabling Regular Expressions allows for the use of regular expressions when searching. Tools such as Regex101 can be helpful in testing Regex searches. Note: Only ECMASCRIPT (JAVASCRIPT) regex expressions are supported.

Event List Panel

The Event List will show all Events for the show. Each Event is represented by a row in the Event List.

At the very bottom of the Event List are additional controls used to create Events and delete Events. On the bottom right of the Event List is the Project information which will show the Project Frame Rate, number of Events in the selected Event Group, and the media duration.

The Event Editor Controls are located in a ribbon to the left of the Event List:

• Align Left - Set the alignment for all selected Events to the left.
• Align Center - Set the alignment for all selected Events to the center.
• Align Right - Set the alignment for all selected Events to the right.
• Position - Update the position of all selected Events using a nine box grid.

• Snap To End - Update the End time of the all selected Events to match the Start time of the next Event.

Event Timeline

The Interactive Timeline is an alternative view of all Events from the Selected Event Group. Events are rendered as Timeline Events based on their Start and End time.

💡 Events without Start or End times will not be displayed on the Timeline.

Timeline Events

Timeline Events will show the Event Text, along with handles used to update the Start and End time. Users can simply click-and-drag either handle to update the time of an Event. Users can also click-and-drag an Event anywhere on the timeline in order to update both the Start and End times at once.

Multiple Events can be moved at once by selecting more than one Event and dragging it on the timeline.

Event Handles

Selected Events will show a green plus (+) icon in the top right corner, used to create a new Event on the timeline. Events created using the timeline will automatically generate based on the timecodes of the selected Event. This means that the new Event will inherit timing based on the previous Event.

Horizontal Zoom

Horizontal Zoom controls are located to the right of the Timeline. Horizontal Zoom is limited to the default values 10, 15, 30, 45, and 60 seconds. The lower the number, the greater the Zoom multiplier. For example, 10 seconds will show 10 seconds of Events within the width of the display.

Save Work

Once editing has been completed, click the Save Work button in the upper right corner of the screen. This will update the appropriate caption file in Cablecast.
