Using Video Recorder Questions With Learnosity

This page explains how to start using the video recorder Question type with Learnosity and explains technical considerations for using it.

Getting Started

To start using the video recorder Question type, contact Learnosity Support. They will need to enable this capability on your account.  

How Does The Video Recorder Question Work?

You can read a summary of the video recorder Question here, along with its configuration options. 

The video data is stored and served via Learnosity as follows: 

  1. Student records a video in the browser, using the video recorder Question type. 
  2. The video is uploaded to Learnosity servers and is queued for processing.
  3. The video is then compressed and re-encoded into an mp4 format.
  4. The original video is deleted from the Learnosity servers.

Timeline of Video Processing

When a student records a video in the browser, it will begin uploading when the student stops recording.

The time it takes to upload the video file depends on the local network connection. A 10 minute video recorded with the video recorder Question type would roughly total 70MB. With a 500kbps upload speed, this can take 2-3 minutes to complete.

Once the file has been uploaded, it will enter a queue to be processed. With the example above, the processing time to re-encode the video into an MP4 format can take up to 5 minutes.

After the file has been processed, it can be immediately viewed. 

Server-Side Processing and Compression

Recorded videos are always resized to 480p (480 vertical pixels) and will respect the original recording's aspect ratio. For example, if a user records a video with a 4:3 aspect ratio, it would be converted to 640x480 pixel resolution. If they record a video at a 16:9 aspect ratio, it would be converted to 854x480 pixel resolution.

The original video recording will be stored until it has been processed, at which point it will then be deleted. If a user tries to view the video before it has been processed, the original file will be served instead. If the browser does not support the playback for the original video format, a download link will be provided.
