How can I record the screen as well as audio on Ubuntu?

Question

That is for creating a video tutorial. I want the screen and my voice. I have tried many recorder, but that only record the screen and internal video.

Answer 1

A simple one is simplescreenrecorder which can be found in the 18.04 repo. Install it with

sudo apt install simplescreenrecorder

start it > Continue > choose size of screen to record > tick the box for audio. For Backend choose pulseaudio. For source choose built in audio analogue stereo which would record the mic instead of the internal audio > choose save location and the default codec parameters should be ok

Answer 2

There is an application in the Official Ubuntu Software Repository callled Kazam, which works great. It will record internal sound, external sound, and the screen. It has pretty good video quality, as well. It can be installed with:

$ sudo apt-get install kazam

If your recording doesn't have microphone sound, make sure to check File > Preferences and try another "Microphone" selection, it may be picking up an unconnected headphone:

The keyboard shortcuts are:

• Super + Ctrl + R: start recording
• Super + Ctrl + F: finish recording, see also: Kazaam how to stop recording?

Answer 3

There are many many applications with which you can do that, The best one that I've used obs, You can install it by

sudo apt install obs-studio

As previously suggested you can also use kazam

sudo apt install kazam

Or if you don't want to install any application, you can use the already available ffmpeg command, the following should work for you:

ffmpeg -f x11grab -s "Your screen resolution" -i :0.0 -f alsa -i default output.mkv

For the last one, I am assuming you're using alsa!

Answer 4

Since ubuntu 21.04, it seems Ctrl+Alt+Shift+R will record the screen.
Quote from:

Make a screencast
You can make a video recording of what is happening on your screen:
Press Ctrl+Alt+Shift+R to start recording what is on your screen.
A red circle is displayed in the top right corner of the screen when the recording is in progress.
Once you have finished, press Ctrl+Alt+Shift+R again to stop the recording.
The video is automatically saved in your Videos folder in your home folder, with a file name that starts with Screencast and includes the date and time it was taken.

If you do not have a Videos folder, the videos will be saved in your home folder instead

Answer 5

You can use recordMyDesktop. It has the option to capture audio from your microphone. To install it run the following command in Terminal

sudo apt install gtk-recordmydesktop

Open recordMyDesktop and just check the box next to 'Sound Quality' before starting recording.

Answer 6

What about the peek app ? I have been long using it and have to admit I have no trouble unlike with Kazam.

Note however that on my system it cannot record audio.

Answer 7

Vokoscreen

This is another decent option, it has good options and defaults:

sudo apt install vokoscreen-ng
vokoscreenNG

Present e.g. on Ubuntu 24.10 and earlier.

Unfortunately I've had a little bit of choppy audio issues recently.
