- While this document focuses on Kaltura Capture, we recommend that users who want to record slideshows with audio narration use Powerpoint for Office 365 itself. Make sure you've got an updated version. Here are additional instructions for Windows, and Mac.
Powerpoint allows you to more easily update your narrated slideshows -
you can not easily update a Kaltura Capture video later. In Powerpoint
you can delete the audio for an
individual slide, re-record and export your presentation as a MP4 and
upload that to Kaltura MediaSpace or share the file itself. Kaltura Capture is more useful for recording yourself using software or guiding your viewer through a
website, etc. - something beyond narrated Powerpoint slides.
- If you need to make longer, more elaborate recordings and do more
involved editing we recommend you consider purchasing a more powerful
screen capture tool like TechSmith Camtasia.
- Consider whether you need to record both your screen and your webcam - especially during the COVID-19 situation during which Kaltura is seeing unprecedented usage. Captures that include both use twice as much data, take twice as long to upload and process. Consider recording a short intro video with your webcam and another video with just your screen.
- Kaltura Capture is a good choice if you need to record yourself using software or walking your students through a website for example - something Powerpoint can't do. We recommend that you keep your recordings reasonably short (4-6 minutes):
- Shorter recordings reduce the cognitive load on the viewer;
- Lapses in the viewer's attention become more frequent with longer videos;
- Updating material is much easier if it is more modular - updating a 5 minute video is a lot easier than a 50 minute video;
- The editing tools in Kaltura MediaSpace don't allow fine-grained edits - especially on longer videos;
- Longer recordings tend to encounter more frequent technical issues. It's less painful if you do happen to encounter an issue on a 5 minute video to redo it than if you do on a 50 minute video. Kaltura Capture is a newer tool and in development.
- For more information please see the Blended Learning Toolkit Video Guidelines article.

Launching Kaltura Capture from Kaltura MediaSpace step-by-step directions
- Launch Chrome or Firefox, go to Kaltura MediaSpace, and login: mediaspace.wisc.edu. If you need more information on how to log in to MediaSpace please see Kaltura - How to Log in to Kaltura MediaSpace (UW-Madison) .
- Click Add New → Kaltura Capture:
- As long as you have previously installed Kaltura Capture (see Kaltura Capture - Installation if you have not installed it) the browser screen will refresh with a message that says "The Kaltura Capture Desktop Recorder:
Your browser may display a notification asking you if you want to open Kaltura Capture:
Check "Always open these types of links in the associated app" if you don't want to receive this notification every time you use Kaltura Capture. Click the Open Kaltura Capture button.
- If you've used Kaltura Capture before, the Kaltura Capture library may appear. If it does, click New Recording:
If you haven't used Kaltura Capture, or if you click New Recording the Kaltura Capture control panel will open:
- Select capture input 1 (also known as the primary input) - if you have multiple monitors or a webcam you can choose which monitor to record or the webcam. You can click the icon for either input to disable it if you don't want to use it. This is the video input that will download if you choose to give your users the ability to download your video. Users cannot download both streams of video - only input 1.
- If you select a monitor to record, Kaltura Capture gives you the option to select Full Screen or Select Area:
If you choose Select Area, Kaltura Capture will display a window of the area you will capture along with 1: Some pre-set window sizes for you to choose from and 2: you can also click and drag the edges of the window to set the recording window size:
- If you have multiple monitors or a webcam you can choose a second monitor to record or the webcam on input 2 (also known as the child input).
Recommendation: Even though Kaltura Capture can record monitors at resolutions higher than 1920 x 1080, all video recorded is reduced to a maximum of 1920 x 1080 pixel resolution. Because of this we recommend you reduce your monitor resolution to 1920 x 1080 or lower before recording so you're not surprised by any loss of detail in recording higher resolution screens.
- Select audio input - Select the microphone to record from. Use a headset or dedicated microphone for best quality. If you watch closely you can see the microphone icon change as you speak to provide a visual indicator of the microphone level. You may also want to review how to set your microphone level in Kaltura - Choosing a microphone and setting levels for recording quality audio (UW-Madison) .
- Click the record button to start recording to start your recording.
Recommendation: Do a test recording of a few seconds. Upload it to MediaSpace and review it to ensure that you are recording the correct inputs and that your audio quality and levels are good before making your full recording.
