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

Update

This article was updated in January 2025. Kaltura has made it much easier to download child entries and the instructions below have been considerably simplified.

Overview

If you've recorded Kaltura Capture, Quick Capture, or specially-configured Zoom integration videos, 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 the same for downloading "normal" Kaltura videos.

Critical Concepts

Prerequisites

You must be the 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), "parent" refers to the stream that contains the screen capture and "child" refers to the stream with the video camera.
You can't download a version 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, you have to download them separately. All downloadable streams should contain the entry's audio.
You can only download the "source" for each stream. That's the highest-quality version.
How to create multi-stream entries: If you're interested in creating a multi-stream entry but not sure how, you can do this by using Kaltura Capture, Quick Capture, or by leveraging the Kaltura-Zoom integration. (Check out this sample dual-stream video if it helps.) You can learn more in the articles linked below:
