Avidemux

Avidemux opens one video file and lets you cut sections out of it, apply filters (crop, resize, rotate, denoise, logo, frame-rate change) and save with a new encoding or by direct stream copy without re-encoding. It suits preparing site or test-camera footage before putting it in a presentation, shortening a long recording, and bringing clips from different devices to one format. It includes projects, a job queue and scripting for automation. Limitation: there is no multitrack timeline, so you cannot build a film from several sources.
