Browser Considerations For Authors/Admins:

  • A high-speed internet connection will ensure the best user experience especially if you are working with online courseware, video streaming or large files.
  • Browser cookies and scripting must be enabled.
  • Pop-up blockers should be deactivated.
  • dominKnow | ONE is designed to function with an SVGA monitor display settings at a minimum of 1024 × 768 pixels. We recommend at least 1280 × 1024 pixels as the display setting. If you have the minimum settings we recommend you put your browser in full screen mode. For more information, see Browser Full Screen Mode.
  • Firewall, caching, and proxy servers and programs may need to be temporarily disabled or bypassed if authors experience issues with the system.
  • Make sure your browser is not set to use proxy settings (see Proxy Settings and Local Area Network (LAN) Settings)
  • Third-party toolbars may need to be temporarily disabled if authors experience issues authoring projects. In many cases toolbars and other add-ons to browsers can use up necessary screen space limiting the available authoring area.
  • If you use Internet Explorer, your dominknow URL should be added as a trusted site for your browser. This URL should also be set to bypass your firewall, caching and proxy server rules.
  • Due to the heavy use of client side JavaScript in the dominKnow Platform using the product with Script Debuggers (firebug, safari developer tools, chrome developer tools) or traffic analyzer tools (firebug net panel, fiddler tool etc) is not recommended or supported. Having these tools enabled will significantly impact the speed, performance and possibly the output of the product.

Browser Considerations For End Users/Reviewers:

  • Plugins such as Flash are only required if you specifically add content that requires Flash (e.g., a Flash file you created). Flash on a desktop is also used for audio/video playback for browsers that don't support HTML5 or the video encoding used by your media.
    Note: Older versions of Internet Explorer don't support HTML5 and require Flash for media playback.
    Note: Packages may be published with the Flash Fallback set to OFF thus preventing older Internet Explorer from render and playing media.
  • A high-speed internet connection ensures the best user experience, especially if the project contains video streaming or large files.
  • Browser cookies should be enabled if required by your hosting LMS.
  • If you content has pop-ups windows then any Pop-up blockers must be configured accordingly.
  • JavaScript MUST be turned on for browsers. (Note: It is rare that it is turned off.)

 

Capture Requirements

System requirements for Capture install are as follows:

  • Mac OSX 10.15 (Catalina) or later
  • Windows 7 Service Pack 1 or later
  • 200 MB of disk space available

 

Before you make your first Capture lesson...

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 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.

Note: To optimize screen snaps, Capture utilizes OpenH264. The first time that this is needed, the application will prompt you to download and install the Cisco OpenH264. If you accept this download, per license terms of Cisco OpenH264, it will install it directly from the source location. You can install or uninstall it in the video preferences of Capture.

If your organization blocks this download, Capture will still function properly, but you will be limited in the number of key frames captured around each screen snap. The URLs that the codec are installed from are:

Windows: https://github.com/cisco/openh264/releases/download/v1.7.0/openh264-1.7.0-win64.dll.bz2
Mac: https://github.com/cisco/openh264/releases/download/v1.7.0/libopenh264-1.7.0-osx64.4.dylib.bz2
