A quick introduction to dominKnow | ONE's feature for creating software lessons

Capture is our feature for creating software lessons.

With Capture you can:

  • Make a single screen capture image
  • Create an animated GIF of a software task
  • Create a software lesson that can be used in a Claro or Flow project in several behavior modes:
    • Show Me
    • Try Me
    • Guide (step by step)
    • Test Me

Capture lessons can also be published as a document.

The Capture application

Capture is an application you download to your computer to record and edit the steps for your lesson. It's the only part of dominKnow | ONE that isn't browser-based.

When you've finished editing your lesson you publish it and then drag and drop the lesson onto a Claro page or into an empty placeholder on a Flow page.

The Capture app is available for Windows and Mac, and your computer will download it the first time you make a lesson. You can also download it ahead of time from the options on the Add to Your Page panel. 

Note: If your organization has managed desktop permissions, you may need to work with your IT team to have the Capture app installed. Contact our support team for help with this.

Starting a Capture lesson

You can start creating a Capture lesson from the Add to your Page panel or from the Record tab on the Ribbon.

Add to Your Page panel

Starting from the Add to Your Page panel adds a new Capture element placeholder to your Claro or Flow page.

You can then choose to create a new lesson or browse the Media Library for an already-created lesson.

This is a good option if you'll be adding the Capture lesson to the page you are currently working on.

Record tab

Starting from the Record tab opens the Capture application immediately. 

You can then choose where to add the completed lesson after you've published it. 

This is a good option if you want to create the Capture lesson but haven't yet decided where it will go.

What does a software lesson made using Capture look like?

Once you've made a software simulation lesson and added it to your Page you can set it to display as:

  • Show Me (an animated demonstration)
  • Try Me (an interactive practice lesson with step instructions)
  • Guide (an easy to follow step-by-step list)
  • Test Me (an interactive practice lesson without step instructions, with eithre one or three attempts for each step)

You can also use Capture lessons as scored test questions or as non-scored Practice questions (these use the Test Me mode).

Here's a link to see examples of each of these. The page will open in a new browser window. It shows the same lesson three times, each set to a different behavior. 

Capturing lessons for browser-based tools or applications 

When Capture is recording a lesson for a tool that is browser-based it relies on the browser's accessibility features to help determine items like the names of buttons or other functions you interact with in the tool.

Different browsers have different levels of support for accessibility, which in turn affects the success of your Capture lesson's recording process.

Your Capture recordings will have the best information if the tool or application you want to Capture is open in Edge for Windows or Safari for Mac. 

The second-best is Firefox for either Windows or Mac. (And Firefox is the best option for Windows versions that don't have Edge, such as Windows 7).

Google Chrome is the most challenging, and to use Chrome you have to turn on the accessibility features (Chrome has them off by default).

To turn on accessibility features in Chrome:

  1. Open a new Chrome browser tab and enter this URL: chrome://accessibility/
  2. Select the "Native accessibility API support" option:


This will apply to making any Capture lesson for applications or web sites you are viewing in Chrome.

Even with accessibility turned on, Chrome provides less information than the other browsers, so we recommend using Edge or Safari if at all possible. If you are not using the best browser option when you start to make a Capture, you will see an alert dialog box.

OpenH264 Video Codec

For authors using Windows, we strongly recommend downloading the OpenH264 Video Codec provided by Cisco Systems, Inc. to improve the Capture recording process.

This codec is not required for creating a Capture lesson, but it does improve the quality of the Capture lessons that you can make.

Using the OpenH264 codec allows the tool to capture a greater range of screen choices when you create your initial recording in Windows.
