Creating, Hosting, and Sharing

How long does it take for videos to process?
Videos generally take about as long as their duration to process in standard definition and double the duration for high definition, so a 5-minute video would be available for playback in SD mode in about 5 minutes and in high definition in about 10 minutes.  Autocaptions are generally available within one hour for all but the longest videos.
Why does my video appear fuzzy or out-of-focus?

Assuming you captured or recorded in clear high definition, this is most likely due to processing that is still occuring.  This is often most obvious with intricate screen recording subjects such as Excel.  If you have just created or uploaded your video, it will take up two or three times the duration of the video for a high definition version of the video to be available.

If you are planning a recording, consider the guidance in "24 tips for Creating High Quality Screen Recordings" for high readablity, high impact screen recordings.

Can I download an MP4 of a video from Kaltura My Media?

If you are the video owner or are a co-editor, you can download an MP4 of your video by entering edit mode.

  1. Login to MediaSpace or Blackboard/Kaltura My Media.
  2. Click the title of the video you'd like to download.
  3. Click Actions and choose Edit.

How do I upload an existing caption file to my Kaltura video?

If you are migrating a media file that has an existing caption file, such as an SRT file, that was created or improved by a human captioner, you should upload this caption file to Kaltura to replace the Kaltura machine captions.  If your media was only machine captioned by another system, the captions are likely lower quality than the machine captions provided by Kaltura.

To replace the machine captions in Kaltura with an SRT that has been created or improved by a human captioner:

  1. Download or locate the existing captions file (e.g. *.srt) from the previous media host or captioner.
  2. Login to Kaltura via Mediaspace or Blackboard/Kaltura My Media.
  3. Click My Media.
  4. Locate the media for which you would like to replace the machine captions and click the title.
  5. Click Actions, then Edit.
  6. Click the Captions tab, then the Upload Caption File button.
  7. Select the captions file, edit the caption information, and click Save.
  8. Click the checkbox in the new caption line to set this caption file as the default for this media.

Kaltura Capture

Can I record system audio using Kaltura Capture?

Kaltura Capture can record your system audio (e.g. sound from a video playing in your web browser) as part of your screen recording if you are using a PC. Recording system audio is not supported in MacOS.

To enable system audio recording in Kaltura Capture, from the Kaltura Capture application panel:

  1. Click the Manage link.


    Audio settings for Kaltura Capture

  2. Click the Settings (gear) icon.

    kalturacapture-audio2.jpg

  3. Select Yes next to Record system audio and click Save.

    kalturacapture-audio3.jpg

  4. The microphone option (Audio Button) must be turned on in the Kaltura Capture panel for system audio to be recorded.  If you are only capturing system audio and do not want to capture sounds picked up by the microphone, use a USB headset microphone with a mute switch/button.

Kaltura Capture is not working properly on my Mac running Catalina.

Beginning with Mac OS X Catalina, applications that record the screen need special permission in the Security and Privacy area of the Settings panel. Without this, you may see odd behavior such as the Capture will not stop recording, the application will not capture the screen, or strange MacOS security messages.

To grant permission for Kaltura Capture to record the screen in Mac OS X Catalina:

  1. In System Preferences, click Security & Privacy, then General.
  2. Unlock the padlock.
  3. Choose "App Store and identified developers".
  4. Lock the padlock.
  5. In System Preferences, choose Security & Privacy then Privacy.
  6. Choose "Camera" and Check Kaltura Capture.
  7. Choose "Microphone" and Check Kaltura Capture.
  8. Choose "Screen Recording" and Check Kaltura Capture.
  9. Lock the padlock.
Can I record the screen of my iPad, Android Tablet, or Smartphone using Kaltura Capture?

Kaltura Capture runs on Windows or MacOS only.  Options for recording the screen include built-in recorders in iOS and Android, downloading a screen recording app from the Apple Store or Play Store, or using a tool such as Explain Everything to record a narrated whiteboard interaction.  For a demonstration of Explain Everything, see the videos below.

Explain Everything on Android

Explain Everything on iOS

Can I use Kaltura Capture to record Flash-based media like Adobe Presenter or Articulate Presenter slideshows?

Yes. As you may know, Flash will no longer be supported on any mainstream browser after December of 2020. Using Kaltura Capture on a Windows PC will allow you to capture the screen video and audio generated by a slide-based presentation published in Flash while you are still able to play it. This video will then be stored in MP4 format in your Kaltura My Media library. MacOS does not allow the capture of system audio and would therefore not be a good option for recording media with audio.

Kaltura Capture will not duplicate interactive features such as buttons or sliders in a more complex/interactive Flash-based animation/project.  See the Migrating Flash-Based Presentations to Kaltura page for more details.

Can I use Kaltura or Kaltura Capture with a document camera?

Yes.  Kaltura Capture can work with any video feed available on a user's computer, including webcams, digital cameras and camcorders, and digital microscopes.  See this video for a discussion of the use of a document camera with Kaltura.

Kaltura Capture freezes at 10% or will not complete an upload. How can I force the upload to finish?

There are several reasons that a Kaltura Capture recording may fail to upload succesfully, including an interruption in Internet access, a memory issue on the computer, or an encoding error.  When one of these occurs, occasionally, the upload will stall (often at 10%).  Try these strategies, in this order, trying to upload after each.

Strategies for Restarting Upload in Kaltura Capture

  1. Quit and restart Kaltura Capture.  Be sure to check the system tray in the lower right corner for the Kaltura Capture icon.  If the icon is present, right mouse click and quit the application.
  2. Restart your computer.
  3. Uninstall and reinstall Kaltura Capture.

If none of these strategies works, you may use the instructions below to upload the content manually.  Contact CITL for further support assistance with the proper functioning of Kaltura Capture.

I am trying to use Kaltura Capture on Mac OS X 10.15+ and experiencing errors installing, recording camera, microphone, or screen, or errors starting Kaltura Capture recordings.

A combination of security changes and features beginning with the October 2019 release of Mac OS X Catalina may result in several issues using Kaltura Capture on MacOS 10.15 and subsequent versions related to system preferences.  These instructions set permissions appropriately for Kaltura Capture.

Enable Camera, Microphone and Screen Recording in System Preferences (MacOS 10.15+) 

  1. In System Preferences, click Security & Privacy, then General. 
  2. Unlock the padlock. 
  3. Choose App Store and identified developers.

I cannot access a video and am receiving a “third-party cookie” error.

Some Kaltura videos embedded in Spring 2020 used an architecture that relied on third-party cookies, which help pass information from Blackboard to Kaltura.  In May 2020, DoIT implemented an update that eliminated the need for third-party cookies in videos added after the update.  Video publishers can prevent this error by simply republishing Blackboard links/embeds and deleting the old versions.  No changes to the actual videos are necessary.

Users can also view videos by enabling third-party cookies in their browsers.

Follow the instructions for your browser:

I have created a Kaltura quiz, with questions grouped closely together or at the same time stamp. Quiz takers are not seeing all of the questions or are seeing questions displayed inconsistently.

This is a known issue in the Kaltura Quiz function related to quiz questions that are place near each other or on the same timestamp.  Kaltura recommends that quiz questions be at least 5 seconds apart.  If questions are too close together, the quiz may act erratically, including skipping questions or displaying an error message.  If you have already created the quiz, the quiz questions can be moved to spread them out further by reopening the video editor and accessing the quiz features.  If authors need assistance or guidance creating or modifying a quiz, see the Creating Quizzes page of the Kaltura support site or contact CITL at citl@niu.edu.

 

I am uploading a video and the video fails to upload, sometimes accompanied by an error message such as "Oops, file too big."

During times of very high demand or with large file uploads, Kaltura will occasionally fail to upload your files.  Kaltura may also be performing system maintenance.  While in general, you should avoid uploading very large video files (>2GB), there is no technical size limit.

You can check the status of the Kaltura system at the Kaltura Status Page.  You might immediately try to upload your file or try again later.  If the problem persists, contact CITL at citl@niu.edu.

Processing and Wait Times

How long should it take to process my video?
Processing time is highly variable, depending on the size, length, and quality of the video and the demand on the system when you create or upload it.  "Normal" processing is between 1 and 3 times the length of the video (e.g. an average 20 minute video may take between 20 and 60 minutes to process).  At times of high demand or for very large videos, it is possible that videos may take 4 hours or more to process.

Analytics

How accurate are the video analytics? Can I use the analytics to assess whether students have watched a video or not?

In our testing, student accounts that view videos are almost always stored in the analytics.  However, Kaltura engineers have indicated that analytics in Kaltura, like analytics on other video platforms, are not designed for assessment purposes, but for viewing patterns, trends, and user data, when it is captured.  While communicating some standards (no cookie blocking, using Chrome, no VPN) will increase the proper collection rate, it would still be possible for the data to be withheld from the user's computer. 

As a video provider, Kaltura tries to balance collection of analytics with ensuring playback.  If browsers had to be carefully tuned in this way to allow viewing with 100% analytics tracking, we would have many more issues with videos not playing.

If you need to know that students watched your videos, consider an in-video Kaltura quiz or a post-video Blackboard quiz to assess objectives addressed in your videos.

Media Storage and Retention

When will Kaltura media storage guidelines take effect?New

Tentative effective date will be June 1, 2021. NIU users with Kaltura media that will be impacted by the new media storage guidelines will receive an email notice on April 15, 2021 and again on May 15, 2021 listing the media items that are pending removal along with steps for how to download and save.

How do I download an MP4 of a video from Kaltura My Media?New

If you are the video owner or are a co-editor, you can download an MP4 of your video by entering edit mode.

  1. Login to MediaSpace or Blackboard/Kaltura My Media.
