SharpCut is a simple video editing utility that allows you to cut individual scenes out of videos without re-encoding.

Other tools like this do exist out there, for example LosslessCut. However, unlike LosslessCut this application is NOT written in JavaScript. It was created to address one of the biggest shortcomings of LosslessCut - abysmal timeline scrubbing performance.

SharpCut is much less featured than LosslessCut, but boasts superior timeline scrubbing performance. This is a big advantage when working on large (and long) video files. Unlike LosslessCut, it does not need to remux containers other than MPEG-4 (.mp4) in order to make files work with HTML5 tag.
