7, DivX format (. Divx) (internal video encoder: divx)
Back in 1998, Microsoft developed the first one (and only) in the PC using the MPEG-4 (Note) encoder, which includes MS MPEG4V1, MS MPEG4V2, MS MPEG4V3 a series of coded cores. Where V1 and V2 is used to create AVI files, and even today it is the default as a Windows component. However, V1 and V2 of the encoding quality is not very good, until MS MPEG4V3 only began to improve, quality has been significant progress. But I do not know what Microsoft's intentions out to shift the MS MPEG4V3 video encoding core enclosed in only applies to Windows Media streaming media technology, that is, we often see the ASF streaming media file. ASF, while the paper has some advantages, but because of excessive closure can not be edited, has not been widely used. This has angered some of the video are not afraid of days is not afraid to delve into video encoding hackers and placed in a master. Later, these groups not only to break Microsoft's video encoding, but also a result of their changes, a new video coding was born. That is the most widely circulated Mpeg4 Encoder ─ ─ DivX3.11.
DivX encoded video files with its greatest extent, not only to restore the original DVD picture quality, but also allows you to select almost all formats of audio, including VBRMP3 even AC3! ! DIVx video coding technology is Microsoft's ASF to break the shackles of the various agreements, from Microsoftmpeg4v3 change from the use of MPEG-4 compression algorithm. DIVX to MPEG4 compressed video, MP3 compressed audio, and to AVI file (. Avi common or. Divx) format exists, Windows operating system, built under the WindowsMediaPlayer essentially be able to play such a file, simply download the MPEG4 - CODEC can be, but the original MPEG4 is not used by the extension of the AVI, so installed the Microsoft MPEG4CODEC after playing as the file format will still be out of the discriminant error, DIVX "official website" On this point, take Microsoft's MPEG4CODEC been modified, and developed a DIVXCODEC, installed only CODEC, can be successfully used WinDosMediaPlayer play DIVX format files.
