IT Services - Download Child Entries of Multi-Stream Kaltura Videos

Overview

If you've recorded using Kaltura Capture or Quick Capture, you've seen multi-stream Kaltura videos. These videos allow users to control the arrangement of the streams within the media player. Users can view two streams side by side, picture-in-picture, or they can view a single stream at a time.

Luckily, in December 2024, Kaltura made it easy to download all streams. The process is nearly the same as downloading "normal" Kaltura videos.

Critical Concepts

Prerequisites

You must be the owner or a co-editor of the entry. Unless you've specifically enabled downloads for your video (which would make it downloadable to everyone), you're not able to download a video unless you're an owner or a co-editor, since you need to perform this action on the so-called "edit page."

Things to Keep in Mind

"Parent" vs. "child": for multi-stream entries, Kaltura uses the terms "parent" and "child." For a dual-stream entry (the most common type of multi-stream entry), the parent is usually the stream that contains the screen capture and the child is usually the stream with the video camera.
You can't download a version of the video from Kaltura that shows both streams at the same time. The Kaltura media player is leveraging functionality to play two separate videos within the same window at the same time. When you want to download these videos, though, you have to download them separately. Note that all downloadable streams will contain the entry's audio.
You can only download the "source" for each stream. That's the highest-quality version.

Steps to Take

For the first three steps, follow the column based on where you're performing the action.

The Kaltura Downloads window, with sections for Main stream, Additional streams, and Captions. A step 6 marker points to the download button for the file under Additional streams.

Click the play button to expose additional controls within the player. (You can pause it immediately afterwards if you want.)
Click the download icon in the upper right corner of the media player. It looks like a downward arrow on top of a line.
You should see several sections of things you can download. The parent is the file under Main stream. Use the download icon(s) in the Additional streams section to download the child(ren).
