Fast Cutvid

There is no HTML, JavaScript, Electron, or webview. The interface is Rust/egui and media processing is delegated to FFmpeg.

That narrow scope is intentional. fastCutVid is designed to open quickly, keep preview and timeline interaction responsive, and produce either a finished simple cut or a precise JSON edit decision list that another editor or AI agent can take into the finishing and release stages.

FFmpeg and FFprobe must currently be installed separately and available on PATH ; they are used for media analysis and final export. Early macOS builds are ad-hoc signed but not Apple-notarized, and Windows/Linux packages are not yet installer-signed.

0.1.2 preview support: macOS provides synchronized video/audio playback. Windows and Linux currently provide silent FFmpeg video preview; exported MP4 files include audio. See the installation guide , release notes , and changelog for setup, limitations, and changes.
