The Kaltura Capture recording application allows you to make recordings on your desktop or laptop computer which can then be uploaded to the QMplus Media service. Kaltura Capture is available at no cost to both staff and students at QMUL and works on both Macs and PCs. You can use Kaltura Capture to record:

  • Any combination of audio, webcam and screen
  • PowerPoint presentations, with audio and webcam. If you record a PowerPoint presentation, Kaltura Capture will automatically detect different slides and create a slide index so your viewers can easily navigate your presentation.

Once you have made your recording, you can upload it to your My Media area. You can then use the online editor to make edits to your recording if required. Once you are happy, you can then publish the recording wherever you have publishing rights. For teachers, you can publish recordings in QMplus course areas. If you are a student, you may have been asked to submit your recording as a video assignment or to the Media Gallery for your module on QMplus. Recordings can also be published on pages in QMplus Hub.

Before starting, please ensure that you have downloaded Kaltura Capture. If you haven’t yet, please follow the steps in our installing Kaltura Capture guide.

Launching Kaltura Capture

There are a variety of places where you can launch Kaltura Capture:

  • From your desktop – after installing the software, you will find a Kaltura Capture icon on the desktop on PCs or in the Applications folder on a Mac.
  • Inside QMplus – wherever you can add content via the text editor in QMplus, you will find a Kaltura Capture option:
  • The Kaltura Capture option in My Media
  • The Kaltura Capture option in the browse and embed dialog box when embedding a recording via the text editor.

On launching the application, you will be presented with the Kaltura Capture window.

In this guide we will be focusing on using the recording options available within this application.

Checking your settings

Before making a recording with Kaltura Capture, you should check the settings which are being used by default. To do this, click on the arrows which show under each video/audio option:

What you see via these arrows will depend on which devices you have connected to your computer. In this example shown below, I can see my 2 PC screens and a webcam as selectable as the 2 video options to record, plus 2 audio sources of which I must choose 1:

Should I wish to turn off a particular source, such as one of the video elements or the audio, then I can do so by selecting the screen or mic icons, as shown below:

If I were to disable all sources, then the Kaltura Capture application will prevent me from recording, by making the record button unavailable:

Once you have selected the audio and video options, you may wish to make a test recording to check what works best.

You can also select the area of the screen which you’d like to capture, should you wish:

You can then either resize the record-able area by clicking on the corner and dragging to increase/decrease the area to be captured, or can select a size from the drop down menu:

Making a recording

Once you have selected your video and audio inputs, click on the red button to start a recording.

You will be given a 3 second countdown before the recording begins.

During the recording, a Kaltura Capture bar will appear in the bottom right of your screen. This will tell you how long you have been recording for and provides you with a few options, which we shall cover below.

  1. Stops the recording, for you to access the options to edit/upload
  2. Pauses the recording
  3. Cancels the recording
  4. Duration of the recording (Hours:Minutes:Seconds)
  5. Microphone audio level
  6. Access to drawing tools (to annotate the screencast)

There are also a number of keyboard shortcuts should you wish to start / stop / pause / resume / cancel a recording:

  • Command/Ctrl + Shift + R  =  Record/Pause/Resume Recording
  • Command/Ctrl + Shift + S  =  Stop Recording
  • Command/Ctrl + Shift + C  =  Cancel Recording

When you have finished click on Done to stop your recording.

  • Preview your recording to check it is as you want it
  • Add tags, for you/viewers to search by
Note that there are no editing tools built-in to Kaltura Capture itself. If you want to edit the recording, you should upload it to QMplus Media and then use the online editor there.

Uploading a recording

Once you are happy with your recording, you must upload it to QMplus Media. You do this by selecting the upload button to the side of it. You will need to be connected to the internet in order to upload.

You can monitor the process of your upload on this screen. How long your recording takes to upload will depend on the speed of your internet connection and the size of your recording file. You will have to remain connected to the internet until your upload has completed.

Once your file has uploaded, the option for upload and the progress status will no longer be visible.

Managing your Kaltura Capture library

The library tab on the Kaltura Capture application shows you all the recordings that you have stored locally and what their current status is.

If you haven’t uploaded a recording yet, this will be indicated to the right of the recording title. You can click to start the upload process. You can also click on the title of the recording to access the options to edit the title or descriptiont or you can click on the delete option to the right of the title to remove the recording completely.

You can follow our guide on adding videos to QMplus in order to add your Kaltura Capture videos to QMplus.

Tips for recording

To get the best results with Kaltura Capture, we recommend:

  • Close down unnecessary applications while recording. Recording can take up a lot of memory so it’s best to have as few applications as possible running when you are recording. Close anything you’re not using.
  • Record in high resolution. This will give you a good quality recording. Make sure you’ve got a good amount of free disk space on your computer.
  • Keep your recordings short. If you want to record an hour long lecture, divide it up into sections and record the sections individually. Not only is it easier for those viewing your recording but a technical failure 50 minutes into a one hour lecture is more difficult to deal with than a failure 5 minutes into a 10 minute recording!
