Video Screen Capture Tools for Linux

Screen capture software for Linux (Debian/Ubuntu/Mint) that records a selected region, window, or the entire desktop along with system audio (and optionally microphone) into a standard video file (MP4, MKV, WebM, etc.). Many of these tools also support live streaming, but the primary focus here is local recording of short-to-medium-length clips. All listed programs should be open-source, and available through the official repositories or simple .deb installation.

• OBS Studio: Professional-grade open-source tool for screen recording and streaming, supports region capture, audio mixing, and plugins; available in Ubuntu/Mint repos via sudo apt install obs-studio.
• SimpleScreenRecorder: Lightweight app for easy rectangle or full-screen recording with audio; low CPU usage and pause/resume features; in repos via sudo apt install simplescreenrecorder.
• Kazam: Simple GUI for quick full-screen or area captures with audio; minimal interface, auto-hides during recording; in repos via sudo apt install kazam.
• VokoscreenNG: Feature-rich recorder with annotations, webcam overlay, and multi-monitor support; cross-platform and actively maintained; in repos via sudo apt install vokoscreen-ng.
• Green Recorder: Supports GIF/video output, area selection, and hardware acceleration; good for low-resource systems; available via PPA or .deb for Debian-based distros.
