Frequently Asked Questions

Everything You Need to Know

What is lossless video cutting and how does it work?
Traditional cloud editors decode every video frame and re-encode them (lossy encoding), which causes compression artifacts and takes several minutes. Lossless cutting uses FFmpeg stream-copying (-c copy), which simply slices between keyframes and updates timestamps in 0.1 seconds with 0% quality loss.
Why is ClipShrink faster than VLC Media Player for cutting videos?
While VLC can record clips locally, its cutting controls are hidden, counterintuitive, and require manual start/stop playback. ClipShrink provides modern dual-handle visual scrubbers and millisecond precision inputs, running locally in your browser with zero setup.
