Kooha, the small free open-source screen recording app, release new 2.3.0 version a few days ago.

Kooha is one of the first apps support Wayland, the default display server in recent Ubuntu and Fedora workstation releases. Since GNOME’s built-in screenshot/screencast tool does not support recording audio, it is a good alternative to record full screen or rectangular area with microphone and desktop audio support. And, it can record your desktop screen into WebM, MP4, GIF, and Matroska formats.

In last 2.2.x release series, Kooha added new area selection UI for better Wayland support. In the new 2.3.0 release, the area selection window now is resizable, so you can have a bigger view when selecting recording area. And, previous selected area is now remembered to make it easy to redo recording last area.

The release also improved the UI, to display current video format as well as FPS (frame rate) in the main app window. The ‘Preferences’ dialog also includes an easy option to select video frame rate.

Other changes in Kooha 2.3.0 include:

• Inhibit idle and log out while recording.
• Progress is now shown when flushing the recording
• Fix audio stuttering on long recordings
• Record audio in stereo rather than mono when possible
• Recordings are no longer deleted when flushing is cancelled
• Fix too small area selector window default size on HiDPI monitors
