divxenc is an advanced and powerful interactive menu-driven shell script written for the GNU/Linux operating system which can help you to encode a DVD, a (S)VCD or a regular video file to the MPEG-4 SP/ASP format using the MEncoder encodert. It supports muxing the final encode from AVI to Matroska, from AVI to OGM and from AVI to the MP4 container.
divxenc has a total of 8 video quality presets ranging from Normal Quality to Insane High Quality. It further has the ability to auto-detect a lot of stuff, like DVD titles, chapters, subtitles, audio streams, and it supports frequently used video filters like scale, crop, dering, deblock, noise, denoise, (un)sharp mask/gaussian blur, deinterlace, interlace, inverse telecine/pullup and hard telecine/3:2 pulldown....
