Frequently asked questions

Using Kaltura

  • Why are we introducing a new video platform?

    The UvA’s current Streaming Media Service has reached the end of its useful life. This has prompted the decision to set up a new platform with functionality that reflects the current use of video by our lecturers and students. The resulting platform is entitled Kaltura. Among many other features, Kaltura allows users to record knowledge clips and videos, save them, play them online and share them with others.

  • Can I use the new platform in Canvas as well?

    Yes, the new Kaltura video platform is compatible with Canvas and gives you access to your own video footage as well as allowing you to record, store and share videos from within Canvas.

  • Can I upload content to Kaltura from my mobile?

    The UvA’s Kaltura MediaSpace environment can also be accessed via the Kaltura MediaSpace Go Mobile app:

    • For iOS
    • For Android

    Install the App, click on ‘Enter URL’ or ‘your site’ and enter Now log in using your UvAnetID and password. You now have access to the UvA’s Kaltura MediaSpace environment. Click on Home, followed by the plus icon in the lower right-hand section. The various options for creating and uploading audio, images and recordings will now be displayed.

  • Does this mean I can no longer access my videos on our old Streaming Media Service?

    No, all media on the old streaming media platform will be transferred to the new video platform Kaltura. However, links in Canvas will have to be adjusted to refer to this new platform. For more information on how to do this, please check out the manual on this page. The 'old' streaming media platform will no longer be available on May 3, 2021. As of 4 January 2020, 9 a.m., uploading to the old platform is no longer possible.

  • Can I upload material to Kaltura without using Canvas?

    Yes, you can. In addition to the Canvas portal, you can also access the Kaltura MediaSpace video portal at Think of this platform as UvA’s very own YouTube channel. Users can upload private content. They will need to log in using a UvAnetID.

    • Click on the video you want to embed on your own website.
    • Click on Share.

    You will have to publish your video as Unlisted first in order to share it this way.

My Media

  • Can I download my own videos?

    You can download your own videos. If you have made the video then you are the owner of the video. Then there is a possibility to download it via Canvas and via the portal If you are not the owner of the video then it is not possible to download it.

    Via Canvas

    At the bottom of the video's bar you will find a download button.

    Via the portal

  • Is there a search function, and how does it work?

    In several places you will find the icon with the magnifying glass. This is the search function. You can search for any terms from the 'details' of your video, such as the name, description, tags, etc. If your videos have captions, you can also search for words from the captions. If you search in My Media and Media Gallery, you can use filters to filter and sort your videos.

  • Can I search for/view/use videos uploaded by other users?

    Yes, videos can be searched via Search at the top right of the portal

    Videos of others can only be seen if you are Co-Editor, Co-Publisher or Co-Viewer, this is determined by the owner of the video. You can determine this at My Media > Edit (pencil) > Collaborations > Media Collaborators


    Using other people's videos is possible if you are Co-Publisher of the video, as described above.

  • Can I set my videos to private? How do I do that?

    Video files used in your Canvas course will only be visible within the course. If you are using videos uploaded through, you can determine whether they should be public or private when publishing to Channels.

    You can use Channels > +Create Channel to create a Channel, which can then be set to Private and shared exclusively with specific individuals. Once you have saved the Channel, you can add specific users on the Users tab and assign them an appropriate role:

    • Member: exclusively has View permissions.
    • Contributor: has View permissions and may add videos.
    • Moderator: has View permissions, may add videos and is assigned the role of Channel Moderator.
    • Manager: has View permissions, may add videos and is assigned the roles of both Channel Moderator and Channel Manager (authorised to assign specific roles and permissions to others).

    Click on Back to Channel and add the videos using the +Add to Channel button.

  • Can I make my videos public (accessible to everyone)?

    Yes, you can do so via My Media.

    • Select My Media.
    • Click on the relevant video.
    • Select the Publish option in the Actions menu.
    • Select the Unlisted option.
    • Click on Save.

    You can also make your videos available by uploading them to a Channel. To do so, log in to

    • Click on Channel, followed by +Create Channels.
    • Under Private, select Public, Restricted.
    • Click on Save.

Uploading files

  • What is the maximum size of a file I can upload?

    There is no maximum size per file that you can post. Keep in mind that the larger a file is the longer it will take to upload. Kaltura recommends a format of 1280x720 pixels and using the H.264 video codec at about 4000 kb/s. Kaltura accepts all common file formats for video, audio and images.


  • What should I enter in the details (metadata) of a video on Kaltura?

    Name (required)

    At Name (required) you give the video a name. This is a required field.


    The Description field gives the video a description that will appear below the name. This is a required field.


    With Tags you can enter the video tags, keywords that characterize the video. By making good use of tags you can categorize videos and thus easier navigate in My Media or the Media Gallery of a course. For example, you could give summarizing videos the tag 'summary', or 'case study' for all videos dealing with a case study.


    At Language you select the language of the video. This is a required field.


    At Author you give the name of the creator of the video. In most cases this is the person who uploaded the video to Kaltura.


    In Department, select the department to which the target group of the video belongs. This is a required field.

    Original ID

    At Original ID you do nothing. Videos that have migrated from the Streaming Media Service have an original ID in this field. Do not delete this field! For a new video, this field is empty and you do not have to enter anything.

    Publishing Schedule

    At Publishing Schedule you indicate whether the video should always be visible on the locations where it is published, or only in a certain period.

  • Why do I need to enter the details (metadata) of a video on Kaltura?

    All the details (metadata) you enter with a video can be used as a search term in My Media or the Media Gallery of a course to find this video. This way, students can also easily find a video. This is especially important when there are large numbers of videos on Kaltura. Thus, filling in the details (metadata) increases findability, searchability and the ability to share material.

Kaltura Capture

  • Kaltura Capture opens by itself without me doing anything, how do I fix this?

    Kaltura Capture should be completely closed after the program is used, for Apple or Windows computers the solution is as follows:

    Apple: In the application bar (at the bottom of the screen), click (with two fingers) on Kaltura Capture -> choose  'Stop'.

    Windows: In the lower right corner of the application bar, click on "^".  Kaltura Capture can be closed by right-clicking on the icon. The exit/quit option will come up, this will close the program completely.

  • Why don't I see Express Capture and Kaltura Capture listed in the +Add New Menu?

    Make sure you are logged in. If Express Capture and Kaltura Capture still do not appear then, it may be due to one the following reasons.

    Kaltura Capture only works on a Windows and Mac computer. If you have a Linux system then it will not work. There is no recording option in Kaltura Capture, however, Kaltura can be further used for, for example, playing or editing videos. 

    For Express Capture the requirements of webRTC must be met. To check whether or not your browser or device supports Express Capture. Follow these instructions:

    1. Go to the website
    2. Click on ''Get Media'' and click on Allow access to your camera.
    3. Wait for the stream: message with accept microphone and image. If it does not appear on the left side of the screen then your browser or device is not supported. 


  • I want to store privacy-sensitive material, is this video platform safe?

    Kaltura is a secure platform that encrypts and stores the material in a European data center. For privacy-sensitive educational material we are working on a specially dedicated place within Kaltura. This will prevent, for example, recordings of vulnerable groups from unintentionally coming out. This feature will be set up at a later date and will therefore not be available on August 1, 2020. For research material with a high data classification Kaltura is not suitable.
