AviDemux is a video editor and encoder which can edit, encode, requantize MPEG and AVI, including DivX. It is almost like VirtualDub, but can also encode to VCD/SVCD/DVD mpg. Most common codecs are supported (M-JPEG, MPEG, DivX, Xvid, huffyuv, WMA, etc.) thanks to libavcodec and libmpeg2. Video can be edited, cut, appended, filtered (resize/crop/denoise), and re-encoded to either AVI (DivX/Xvid) or MPEG 1/2.
