FAQs: Technical Information


Where are the videos stored?

Unless otherwise specified, they will be stored in our secure Amazon cloud storage. We currently use Amazon’s US East (Northern Virginia) Region, with a Europe region to be available soon.

What are the privacy and security considerations?

GoReact is designed from the ground up as a private video service, giving you control over what is shared. All videos are private by default, and are only available to others based on the instructor/account holder's settings. GoReact also does not share any student's grading with other users—only the student and instructors/reviewers may see that information.

For more on privacy, see our Privacy Policy.

For more on security and compliance, see our Compliance page.

How good is the video and audio quality?

Video on GoReact will by default record to a 360p quality setting (same as YouTube standard). While it will not record higher resolutions due to bandwidth and storage considerations, using an HD-quality webcam will typically result in crisper 360p video than a standard webcam. Audio quality is determined by the quality and placement of the microphone connected to the webcam.

As a general rule of thumb, you can expect GoReact recording results to be similar to whatever quality you can get using Skype from the same computer.

What are the computer requirements for GoReact?

GoReact works great on either Windows or Mac, and runs entirely in your web browser. As a cloud-based service, there’s no software to install. All you need is internet access. To record, you’ll need Adobe Flash to be enabled in your browser as well as a connected webcam (see What cameras work with GoReact?).

For best results, here's what you should have on your computer:

  • OS: Windows 7 and up or Mac OSX (current or most recent previous version).
  • Web browser: Chrome, Firefox, Safari, or Edge (current or most recent previous version).
    Note: GoReact is not supported on IE 10, IE 11, Safari 8 or older versions of either browser.
  • Adobe Flash (current version) and webcam if doing live PC recording.
  • PC hardware: for best performance, processor and video card should be less than 3 years old, and you should have at least 4GB of RAM.
  • Windows RT tablets are unsupported and will generally not work with GoReact.
  • Please make sure to disable any ad and script blockers (or whitelist www.goreact.com) as these can interfere with GoReact's functionality.

Chromebook users

GoReact's video features can be resource-intensive (especially on stimulus activities where two videos stream simultaneously). Due to the widely varying hardware and (often limited) system resources in Chromebooks, GoReact may not perform well in some cases. In our testing, more robust, higher-end Chromebooks generally work fine, while less expensive and/or older Chromebooks will struggle. If your GoReact experience on a Chromebook isn't satisfactory, you'll need to use a different device.

Source media requirements note: For recording/playback of videos paired with Source Media, the requirement for a newer computer is more significant since it is processing 2 videos simultaneously. Note that source/response videos are currently not supported on mobile devices. For more information, see our Using Stimulus Media guide.

Network considerations

Baseline internet speeds should be at least 1.5Mbps download and 0.5Mbps upload with a consistent signal for successful recording (up) and playback (down). You can test your current speed at https://www.speedtest.net.

If you are running into unexpected behavior, network/IT administrators should ensure the following are available for users:

  • Ports 80 & 443 (should be standard, we'd think...)
  • Port 1935 (for RTMP Flash recording—will fall back to 443, but better if 1935 is open)
  • Do not block the host pubnub.com, which provides CDN/connectivity services to the GoReact application
Does GoReact work with mobile devices?

GoReact is designed in HTML5 and works on mobile platforms such as iOS and Android. Further optimization for mobile devices will be happening over coming months. However, there are a few limitations.  Recording directly on our website in your mobile browser is not yet possible since this requires Adobe Flash and Adobe doesn't support Flash on mobile devices.

We are close to completing our own recorder which will eliminate Flash from the equation and will allow direct recording very soon!  Live Event and Stimulus Video Response activities require a PC, unless your activity is such that recording outside of GoReact and uploading your video separately is acceptable.  In that case, you can upload through your mobile browser.

For best results, here's what you should have on your mobile device:

  • iOS or Android operating system (current or most recent previous version)
  • A Wi-Fi connection is strongly recommended instead of data for video uploads on mobile devices (they can be big files.)
