About:

Video for Windows and DirectShow codec based on VFW code from XviD project and using libavcodec library from ffmpeg project for compression. Few other compression libraries are supported too.

Features:

- various compression methods:
    MPEG 4 compatible (Xvid, DivX 4, DivX 5) using libavcodec or XviD
    Divx 3 compatible, MSMPEG4v2, MSMPEG4v1
    WMV1/7, WMV2/8
    H263, H263+
    HuffYUV in YV12 colorspace
    MJPEG
    MPEG 1
    Theora (not for regular use, format isn't stabilized yet)
    MPEG 2 by using mpeg2enc code from MJPEGtools project
    all Windows Media Video 9 supported encoders with output to asf/wmv file or AVI
- all common encoding modes: constant bitrate, fixed quantizer, fixed quality, two pass encoding (depends on compressor features)
- for libavcodec and XviD detailed selection of motion estimation method
- minimum and maximum I frames interval
- minimum and maximum quantizer selection, quantizer type and trellis quantization selection for libavcodec
- adaptive quantization (aka. masking) for libavcodec and XviD, single coefficient elimination
- selectable compression of starting and ending credits
- two curve compression algorithms for second pass of two pass encoding - thanks to XviD developers
- second pass simulation: although not very precise, still helpful for tweaking advanced curve compression parameters
- ability to use libavcodec internal two pass code
- image preprocessing with ffdshow image filters (latest ffdshow version must be installed)
- graph during encoding: if your encoding program doesn't provide one
- B frames support: from one to eight consecutive B frames
- support for MPEG 4 quarterpel and GMC
- selectable interlaced encoding
- decompression
