Video Screen Capture in Linux

Built-in screen recorder available in the GNOME desktop environment, which is used by distributions like Ubuntu, Fedora, and Red Hat Enterprise Linux.

To start recording, press the keyboard shortcut Ctrl + Alt + Shift + R, which activates the screen recording feature. A red circle indicator appears in the top-right corner of the screen to signal that recording is in progress. The recording can be stopped by pressing the same shortcut again. The resulting video is saved in the WebM format in the ~/Videos directory, with filenames starting with "Screencast" followed by the date and time. By default, recordings are limited to 30 seconds, but this duration can be extended by modifying the gsettings configuration using the terminal command gsettings set org.gnome.settings-daemon.plugins.media-keys max-screencast-length followed by the desired time in seconds. Setting the value to 0 removes the time limit entirely

WebM is a horrible format.

While earlier versions defaulted to WebM, GNOME 46 and later (such as in Ubuntu 24.04+) can record in MP4 format if the necessary codecs are installed.

Specifically, if gstreamer1.0-plugins-bad and restricted codecs (like ubuntu-restricted-extras) are installed, GNOME Shell automatically uses an H.264 pipeline and saves recordings in MP4 instead of WebM. This change was implemented in GNOME 46 via a merge request adding H.264 encoding support.

For users on Arch Linux or other systems using Wayland, tools like wf-recorder and green-recorder can be used via the command line to capture screen video.
