Avidemux

Avidemux is a multi-platform video editor that performs some basic and not so basic operations for a video sequence.

Cut, apply filters, and recode are the three main activities that you can do with this program.

The filters are organized by categories. They come in all types: those that transform the clip features (crop, rotate, flip, dissolve), reduce noise, adjust the color, shape, rewind, etc.

Also, Avidemux includes a number of predefined formats that you can use to export the movie to DVD, PSP, FLV, MP4, VCD, or SVCD.
