In simple English
ScreenArc is a free desktop application for recording your computer screen. It watches your mouse movements and automatically zooms in where you click. This makes software demos and video tutorials look polished without manual editing. You download the installer for your operating system and run it. The project is fully open source under the GNU General Public License version 3.
What it is
ScreenArc is a cross-platform screen recorder and video editor built with Electron (a framework for building desktop apps using web technologies) and FFmpeg (a command-line tool for processing video and audio files). It generates smooth pan-and-zoom animations based on mouse activity and provides a timeline for trimming and styling clips.
What it is good for
This is good for solo builders, developers and educators who create software tutorials or product demos and want professional-looking zoom effects without spending hours on video editing.
