The Tools menu contains a number of functions which may be useful for authoring captions and/or descriptions.

The functions include various pre-flight checks (Check Timecodes, Check CEA-608 Compliance) which might otherwise be flagged during Export attempts, as well as tools for alleviating errors found by those inspections (Offset Timecodes, Show Ruler).

There is an additional tool for converting a caption project with timecodes to a description project.

Finally, CADET preferences are accessed from the Preferences menu item.

Check Timecodes

The Check Timecodes tool checks the start/end times to make sure that there are no anomalies, such as out-of-order (i.e., non-ascending) timecodes.

  1. Open the Tools menu and select Check Timecodes.
  2. Errors will be displayed as links in the Status area. Clicking on a link will move the cursor to that error in the editor.

The image to the right shows a sample timecode error, where a caption's start time is specified before the preceding caption's start time).

Offset Timecodes

The Offset Timecodes tool allows you to easily change the timecodes for a block of captions.

  1. Open the Tools menu and select Offset Timecodes.
  2. Errors will be displayed as links in the Status area. Clicking on a link will move the cursor to that error in the editor.
  3. Learn more about offsetting caption timecodes.

Check CEA-608 Compliance

The Check CEA-608 Compliance tool makes sure that the captions can be successfully exported to the .SCC format. Note that each caption row may not exceed 32 characters (see the Show Ruler tool for more information).

  1. Open the Tools menu and select Check CEA-608 Compliance.
  2. Errors will be displayed as links in the Status area. Clicking on a link will move the cursor to that error in the editor.

The image to the right shows a sample line-length error, where the second row contains more than 32 characters.

Show Ruler

The Show Ruler tool displays a 32-character ruler above the current caption. This will help you determine when rows are too long for the .SCC format. When the ruler is visible, CADET shows the caption column in a monospaced font .

  1. Open the Tools menu and select Show Ruler.
  2. The ruler is displayed above the current caption.

Presentation Mode

The Presentation Mode tool puts the player in full-screen mode. This can be useful for reviewing a project or for playing the media with captions and/or descriptions in a classroom or other setting where a large screen is desirable.

For description projects in CADET, pressing the shortcut key while holding down the Shift key will suppress the on-screen display of the description text, thus providing a realistic, TTS-described presentation. (Read more about reviewing TTS descriptions.)

  1. Open the Tools menu and select Presentation Mode.
  2. The screen is switched to full-screen mode.
  3. To exit full-screen mode, press the Escape key.

Convert to Descriptions

The Convert to Descriptions... tool converts a caption project into a description project. Note: A CADET project can contain audio descriptions or captions, but it cannot contain both. If you want to write captions for the video that you are also describing, you must create a separate CADET project.

  1. Open the Tools menu and select Convert to Descriptions.
  2. The new CADET description project is displayed, and the Save As dialog is shown.
  3. Save the project.

After saving the project, you will see a new editing grid with an additional Audio Cue column. The text in this column represents the caption that appears just before the pause in the audio where a description will be inserted. Also note that the timecodes in the Start and End columns correspond to any gaps in the display of captions: that is, the end time of a caption has been converted to be the start time of a description, and the start time of a caption has been converted to be the end time of a description.

Preferences

The Preferences... tool displays all the adjustable CADET preferences.

  1. Open the Tools menu and select Preferences.
  2. Edit the choices as appropriate.
