KB-000351: Can you describe to us the process and procedures for post production closed captioning in your OnCue product?


Impatica OnCue does not provide “Closed Captioning” in the sense that each word appears on the screen and is highlighted in some manner as it is spoken. The software does provide a scrolling script that has the current paragraph highlighted for the viewer. The level of minutia that is depicted in the paragraphs (scrolling script window) is dependant on the intent of the OnCue project author. In other words, you could have the software highlight a paragraph of text (containing 3 or 4 sentences) at a time, a single sentence at a time or a single word at a time. Our usual recommendation is that a paragraph of not more than 2 sentences be highlighted at any one time.


The process for achieving this in an OnCue project is as follows:


1-      Transcribe the audio or video file so that a verbatim transcript is available.

2-      Within the PowerPoint presentation, place the portion of the transcript that applies to each slide in the notes section of each slide.

3-      Arrange the notes, within the notes section of each slide, into paragraphs. As stated earlier, a paragraph could consist of several sentences, 1-2 sentences (our recommendation), or a single word. A paragraph is delineated by inserting a hard return in the notes. Instead of allowing word wrap to start a new line, simply press the “Enter” key to place the cursor on the next line (this is a hard return). Hard returns are interpreted by the Impatica software as a new paragraph. Note also, that a new slide is also treated as a new paragraph.

4-      Once you have arranged the notes as you would like them to appear, save the PowerPoint file.

5-      Launch Impatica for PowerPoint and add the PowerPoint file to the software.

6-      Within the software, click on the “Slide Show” tab.

7-      Ensure that the “Include playback controls” checkbox is not selected.

8-      Click on the “Extra Output Files” tab

9-      Within the “Exported Notes” frame ensure the “OnCue script file” and “Include paragraph cue points” checkboxes are selected.

10-   Click the “Impaticize” button to convert the PowerPoint file into the Impatica format. During the conversion process, the software will also produce an OnCue script file. The script file will contain paragraph indicators for every hard return it encounters in the notes section of each slide.

11-   Once the conversion is complete, close the Impatica for PowerPoint software.

12-   Launch Impatica OnCue and create a new project or open an existing project.

13-   Add your assets to the project. Ensure that you select the “Presentation Impatica file” (–imp.jar ) and “Script text file” (.txt) that was produced in step 10.

14-   In addition you will need to select the other required assets – “Source video/audio file” and the “Template Impatica file”.

15-   The final asset is the “Marker text file”. This asset is produced within the edit window of OnCue. The marker file contains the information required to keep the PowerPoint slide transitions, animated objects and paragraph changes synchronized with the audio/video file.

16-   Click the “Edit” button on the “Project Assets” tab to launch the edit window.

17-   Within the edit window you are able to indicate when the slides should transition, when (and for how long) a paragraph should be highlighted and when the PowerPoint animations should occur. An explanation of the edit window can be seen within this tutorial presentation:
Once the presentation begins, click on the “Edit Window” menu item on the left-hand side of the presentation to skip to this topic. This tutorial was created with OnCue and notice that there is a scrolling script window on the top-right that shows the paragraph currently being spoken.

18-   With the editing complete, save the marker file. It will automatically appear as the fifth and final asset in the project.

19-   Adjust any remaining settings as desired– e.g. video speeds to produce, etc. and click on the “Impaticize” button.

20-   The OnCue presentation will be created with closed captioning (or as we term it: a scrolling script) in place.



Impatica OnCue presentations are intended to include a scrolling script (closed captioning). The detail of the captioning is flexible and easily controlled by the project creator. Students requiring closed captioning can easily be provided this presentation component when the content is created with Impatica OnCue.
