The Kaltura Player

The Kaltura Player is the front-end interface used to view captured videos and/or presentations from Kaltura Capture Applications. The Kaltura Player  may provide you with multiple interactive viewing options, such as Picture-in-Picture, Side-by-Side, and other displays depending on how the video was recorded. The following screen displays the viewing options available in the Kaltura Player.

Dual Stream for multiple videos – Enables you to view two concurrent streams such as the presenter, the classroom, or the presentation, that are taking place during the same event. You can choose to view them as Picture in Picture, or Side by Side. Regardless of the view you choose, both streams are synchronized to the same point in time.

Tour of the player

Navigating the Video

The Kaltura Player’s navigation menu opens up the chapters and displays the slides for the Kaltura CaptureSpace recording.

Slides and Chapters

You can browse through the chapters and slides in the recording in the Navigation Panel. You can click on a chapter or slide to jump to that point in the recording.


Use the Search option to find specific content or specific slides in the presentation. Start typing in the text box and it will auto-complete your search term, making search faster and easier.

Dual Stream for Dual Stream Videos

Kaltura provides the ability to run 2 streams side by side (presentation or video as second screen). You can choose to view them as Picture in Picture, or Side by Side. Max of 2 videos streams playing together. If the cue-points are presented (presentation) only one video can play in parallel.

Only the main stream can include an audio file – the second stream is muted by default.


The following are current limitations for the dual stream player:

  • IE7/IE8 are not supported. (including compatibility modes)
  • Assumes all streams have the same audio track and the audio track is part of each stream
  • Assumes captions files are added to all streams, not just the main stream
  • Not supported on iPhone or Android
  • Supports up to 5 connected streams (5 videos or 4 videos + slides)

Viewing Machine Captions and Closed Captions

All recording uploaded to kaltura will automatically have machine transcriptions applied to the media.. Machine transcriptions are created when the server attempts to create text from human speech. This transcription will have errors and is not considered a true closed caption under AODA guidelines.  The owner of the media has the option of correcting the machine transcription if they wish to do so. The owner also can upload actual closed captions if they wish. Please note that machine transcription does take longer to appear than the media as the machine transcription process takes longer.

Machine captions and closed captions are displayed in Mediaspace inside of the player, on top of the video as you can see in this example;
