Screen Recorders For Ubuntu - Kazam

Kazam là phần mềm quay phim màn hình tốt nhất hiện nay trên Ubuntu. Đây là trình quay phim màn hình đơn giản và dễ dùng cũng như rất dễ cài đặt.

- Cài đặt Kazam với lệnh sau:

sudo add-apt-repository ppa:sylvain-pineau/kazam
sudo apt-get update
sudo apt install kazam

You also need to install a few libraries in order to record the mouse clicks and keyboard presses.

sudo apt install python3-cairo python3-xlib

Some of the main features of Kazam are:

• Record entire screen, part of the screen, application window, or all screens (for multi-monitor setup)
• Take screenshots
  
• Keyboard shortcut support for easily pausing and resuming while recording screen
• Record in various file formats such as MP4, AVI, and more.
• Capture audio from speaker or microphone while recording the screen
• Capture mouse clicks and key presses
• Capture video from the webcam
• Insert a webcam window on the side
• Broadcast to YouTube live video 

-  Recording your screen with Kazam

• Start Kazam in the application menu. You can check the options as per your need and click on capture to start recording the screen with Kazam.

• The default wait time is 5 seconds
• Once the recording starts. If you want to pause or finish the recording, you can click pause or finish

• If click finish recording.  it will give you the option to “Save for later”

• By default, the video will be saved in the Video folder

• You can access its advanced or additional features from the preferences.

Autosave screen recording in a specified location

You can choose to automatically save the screen recordings in Kazam. The default location is Videos but you can change it to any other location.

Avoid screen recording in RAW mode 

You can save your screen recordings in file formats like WEBM, MP4, AVI etc. You are free to choose what you want. However, I would advise avoiding RAW (AVI) file format. If you use RAW file format, the recorded files will be in GBs even for a few minutes of recordings.

It’s wise to verify that Kazam is not using the RAW file format for recording. If you ask my suggestion, prefer H264 with MP4 file format.

Capture mouse clicks and key presses while screen recording 

If you want to highlight when a mouse was clicked, you can easily do that in the newer version of Kazam.

All you have to do is to check the “Key presses and mouse clicks” option on the Kazam interface (the same screen where you press Capture).

Use keyboard shortcuts for more efficient screen recordings

Imagine you are recording screen in Linux and suddenly you realized that you have to pause the recording for some reasons. Now, you can pause the recording by going to the Kazam indicator and selecting the pause option. But this activity of selecting the pause option will also be recorded.

You can edit out this part later but it unnecessarily adds to the already cumbersome editing task.

A better option will be to use the keyboard shortcuts in Ubuntu. Screen recording becomes a lot better if you use the shortcuts.

While Kazam is running, you can use the following hotkeys:

• Super+Ctrl+R: Start recording
  
• Super+Ctrl+P: Pause recording, press again for resuming the recording
• Super+Ctrl+F: Finish recording
• Super+Ctrl+Q: Quit recording

Super key is the Windows key on your keyboard.

The most important is Super+Ctrl+P for pausing and resuming the recording. 

You can further explore the Kazam preferences for webcam recording and YouTube live broadcasting options.
