Sometimes it becomes extremely necessary to create screen recordings. Very useful when you want to teach something, like installing some software or demonstration resource. On Windows and Mac OS there are lot of excellent software that fulfill this task very satisfactorily.
However, on Linux, this task is not as easy as on Windows or Mac, Simply because the Linux platform had not achieved the popularity to attract good companies in this area to carry such software. However, it is still possible to find good free programs to accomplish this task. Today we present the Kazam, a competent software for recording screens. Let’s talk a little bit about it.
The Kazam is a open source software developed in Python (Python is widely used in Linux), which has simple interface and focused on its core skills: recording screens.
On the main screen you can see the options for screen recording. In the highlighted tab, you can see the option for area to be recorded (whether to record the whole screen, selected window or just a specific area). In addition, you can see options for the inclusion of some important details in software such as the mouse cursor and sounds of the speaker and microphone.
The most useful feature, that’s really very nice for an open source software, is support for formats. The Kazam supports the following output formats for screencasts:
- WebM (open source video format created by Google)
- MP4 (Its main feature is the great compatibility with software and devices)
- AVI (Its main feature is video quality)
Furthermore, it is also possible to select the frame-rate (number of frames (pictures) per second).
In this tutorial we will teach installing Kazam in Ubuntu. This process should work in all Ubuntu versions.
1 – Open the command line (CTRL + ALT + T) and enter the following command:
sudo add-apt-repository ppa: kazam-team / stable-series
sudo apt-get update
sudo apt-get install -y kazam
2 – On the first command, you will be prompted for your root password. After that enter all other commands one by one. After that, just close the terminal and normally open Kazam from the Ubuntu App Panel. Simple, right?
Recording a screencast with Kazam
In step-by-step below, you will learn how to record a screencast ready for sharing online, in formats suitable for both YouTube and for Dropbox (for quick shares).
1. Open Kazam, go to File (top menu) ~> Preferences. Select the input devices and sound output, as shown in the image below.
2. Go to the “Screencast” tab and enter the amount of frames with which you want to record the screen and the output format (select H264 / MP4 to share more easily on the internet). Close the window, and go to the main Kazam window.
3. Select the area you want to record, what you want to put in the video (the mouse cursor, the speaker sound or microphone sound), enter an initial delay for the video recording and click “Capture”. Ready! Your screencast is being recorded!
4. Finally, simply visit the Kazam the context menu, available right next to the icons at the top of the screen, and click “End recording”.
5. The program will suggest you to edit the recorded video at some video editor. To do this task, obviously you will need to have Video Editor program installed on your machine. If you want to ignore the statement, simply click “Save for Later” and click Continue.
6. The Kazam will then ask you to select a folder and file name for the file to be saved. Select the folder and file name and notice: there is NO rendering time. i.e. you do not need to wait for the screencast is finally rendered.
With all these procedures, you already know how to record screen on Linux using Kazam. No doubt, Kazam does not meet the standards of the great screen recording programs available for other operating systems, but it fulfills this task in a simple, fast and efficient way.
