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

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.

Solution 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

Solution 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

Solution 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!

Solution 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
