Kaltura (Personal) Capture allows a user to record in various ways and upload the created content to the videoportal afterwards or save it locally.

The recording can be set up with a combination of up to three of the following options:

  • Microphone.
  • Webcam.
  • Screen.

A good recording requires a decent computer (64 bits Windows or Mac) with 4gb memory, 1gb free storage and four processor cores and we recommend to close all applications that are not directly needed for the recording.

Having the Remote Desktop open is strongly discouraged.

Kaltura Capture does not work on the Linux operating system! Alternatively you can use the Kaltura Live Room option. Please set up a private channel for you alone and record the session. Steps for this are explained in chapter 14 of this manual.

It is also important to note that you computer has to have a 64 bit operating system and at least 4GB of memory, 1GB of disk space and at minimum a intel i5 core with 4 or more processors! For a total list or requirements see the link below:


Please follow all the steps to start recording with Kaltura Capture! Do not skip steps! Always log in first!

First of all, we need to install the application.

  • Navigate to the video portal (video.leidenuniv.nl) and log in.
  • Click on the ‘Add New’ menu  option on the top right side of the page to expand the menu.
  • Select ‘Kaltura Capture’.
  • Tick the box to agree with the terms of service and continue the process.
  • In the newly appeared section below the terms of service select the appropriate download (at the bottom of the screen) for your computer (Windows or Mac).
  • Select a destination for the file, generally this should be the ‘Downloads’ folder.
  • Either open the downloaded file from the browser by clicking on the downloaded file button on the bottom left of your browser or browse to the file from Explorer or Finder and open it from there.
  • Choose to run the installer and follow the on screen instructions.

Note: Once finished installing the application will NOT open automatically.

Note: Do NOT open the application from the desktop. Follow these steps to start the application:

After the installation has finished you are ready to start recording with the Kaltura Capture application.

  • Navigate back to the video portal (video.leidenuniv.nl) and again select ‘Kaltura Capture’ from the ‘Add New’ menu.
  • Tick the box to agree with the terms of service and continue the process.
  • This time you will get a popup. In the popup click ‘Open Kaltura Capture’.
  • After a few seconds a splash screen will appear and the application will start.
  • In the screenshot below you can see a big red “Start Recording” button, two screen icons, a microphone icon and the “Manage” button.
  • If by accident you clicked to another window at the time the application opened you can bring the application to view by either clicking on the icon in the taskbar or dock or using alt-tab to locate the application.

Prior to starting your recording it is a good idea to check the settings tab for Kaltura Capture. Depending on what you are planning to record you should adjust your settings accordingly and always test your recording settings before putting all the effort into creating a product as the settings might need adjusting to optimize quality and smoothness.

  • Click on “Manage” in the recorder window.
  • Click on the settings tab in the Kaltura Capture window (second icon to the left menubar):

In the settings screen you have multiple methods listed with a few options on quality or whether it should record in the first place.

  • The Camera and Screen recording settings are generally fine for most purposes. We would never recommend a lower screen or camera recording quality. A higher camera recording quality however can be beneficial when you want to show objects on camera in detail. In such cases turn the quality up to 1080p!
  • The option to record system audio (this included Windows sounds but also sound on a video you are playing from YouTube for instance) is turned off by default. If for any reason you require system audio to be recorded please turn this option on.
  • “Recording name prefix” allows you to record files with a prefixed title beforehand this option is very useful when you decide to record a series of video’s under the same name.
  • “Highlight Cursor” is turned on by default and will highlight your cursor when you click anywhere on screen (color of highlight can be set during recording).
  • With the option “Auto minimize when recording” enabled the Big Red Record Button will automatically hide itself whenever a recording starts. This will allow you to make a recording without also having the Big Red Button in the recording.The option is turned on by default.
  • The last option is for diagnostic purposes and should generally not be used unless requested by staff.

As said we always recommend you to test your settings prior to recording your actual video. Especially your microphone needs to be properly set. A few tips to improve quality and how to adjust microphone volume are:

To check your settings please click on the “New Recording” button on the top right of the Kaltura Capture window (see screenshot below) to return to the recording window.

Please create a test recording and check the result. You are now ready to learn how to use the application, please follow the instructions of the next chapter to create a (test) recording.
