Which browser and operating system we could get which Moodle Kaltura webcam assignments to work in

Below please find our current (work in progress) test matrix. Use one of the combinations that worked (“YES”) to avoid problems when taking or grading webcam assignments (or come to the LRC where we set up a working combination). You can view your version of the Kaltura video player and of Adobe Flash by right-clicking on the Kaltura video window.

Delete the Flash Global Settings if the iMacs webcam displays black frame only

  1. Problem: Safari and (not recommended after last testing round) Firefox both hung on iMAC6 when a student tried to do a Moodle Kaltura Webcam assignment and got to the built-in ISight camera display page.
  2. Cause: maybe a Flash security problem accessing the web cam? maybe security dialogue was not answered by the student correctly earlier, and the “preference”stored in her account?
    1. Solution (presumably): System started working again after I deleted the Flash Global settings, by right-clicking on the webcam video preview window like so: CIMG0020

  4. Ceterum censeo that we need a computer management infrastructure if we want to use MACs for language learning technology. Faronics-Deepfreeze would have prevented this problem, provided we have a software imaging system (CASPER coming up apparently) that can let us start with a usable image, and the staff time to learn and configure 2 usable OS images and dual usable computer management infrastructures. TCO now > TCO dual OS infrastructure > TCO web cams for 45 PCs. 

How students upload a video file to Moodle using Kaltura

  1. My closest related instruction so far has been for teachers, and the CTL also seems to have only instructions for how teachers upload videos for students. However, instructions for students are very similar, follow these steps:
  2. Open the kaltura assignment and click “Add video submission”:clip_image001
  3. Under left tab “Upload”, Click “Browse”:  clip_image002
  4. Browse to your video file (note the “files of type”allow only the upload of certain extensions) and  click “Open”: clip_image004
  5.   Click “Upload”clip_image005
  6. Wait for the upload to complete: clip_image006
  7.   Click “Next” :clip_image007
  8.   Add at least a “title”, and fix any errors you might get:  clip_image009
  9. Click “Next”: clip_image011
  10.   Click “Submit”: clip_image012
  11. Look for the success message: clip_image013
  12. You will have to wait for the video preview to become available:clip_image014
  13. If you refresh the page, the wait time gets updated, take the amount with a grain of salt.  Here I could already view… image
  14. Be aware that your video resolution will likely be downscaled (my 1280*1024 screencast in this example ended up pretty grainy).

How to do successful Moodle-Kaltura webcam recording assignments

Kaltura turned out to have a number of limitations, and we have some of our own in the LRC. Both required some debugging and finding of workarounds, which you can benefit of if you follow carefully our step-by-step guides for teachers or for students.

Q:Concurrent exam scheduling

Sanako has no scheduling system to allow a limited number of users to take an exam simultaneously (but it prevents users beyond the licensing seats to use the Sanako, including for exams), Scheduling plug-ins seem to be available for Moodle.

Outlook: Need more licenses for the Sanako to match the UNCC class size

How to stream video clips to students in classroom and at home, using Moodle Kaltura

  1. DVDs are getting a bit long in the tooth, not to mention VHS, and can form a real obstacle or time-consuming distraction in an educational setting, from handling the media to finding compatible software and/or hardware players for the media.
  2. Fortunately, there is a now a better way to make video clips available to students than uploading them to YouTube.com:
    1. university-supported,
    2. more compliant with copyright and fair use restrictions (which still apply)
    3. also requiring only a web browser (available on all campus computers, including teacher computers in classrooms, including those that have no (region-free) DVD-player installed)
    4. and a course enrolment. But access to a Moodle course can  now be considered a given, both for teachers and students.
  3. Moodle Kaltura allows for easy
    1. uploading of a video file by the teacher
    2. viewing by the student (streamed – Flash required, not different from YouTube.com).
  4. View a screencast example how easy it is with Moodle Kaltura to upload and playback a video clip from a movie DVD.
    1. Not different from YouTube.com, you still need to edit out the segment from the DVD that you want to show in your class,  uploading a full DVD I do not intend to test.
    2. From this example, you can also get an idea how long the server-side encode takes before the video an be streamed back to students: the short clip of a few minutes here starts playing back at 12:40. Naturally, a teacher would prepare their course, including all video uploads, before the term starts or possibly before the week starts, or, in extremis, before the class starts – in practice, only the – extremely unlikely – scenario where the teacher would try and upload the video during the class is not supported.
