Everything you wanted to know about MPEG-4 / DivX, but was hesitant to ask last part

DivX

Resume

DivX

DivX is a progressive implementation of the MPEG-4 format. It offers a significantly higher video compression ratio and brings a number of groundbreaking innovations.

Applications for MPEG-4 include multimedia applications for mobile use and the Internet, digital television, home video, and mobile communications. With the advent of specialized processors, it was possible to create inexpensive universal fixed and mobile players that, in addition to DVD movies and popular formats, also play files based on the MPEG-4 format. Today, the price, performance, and format compatibility of players have reached a point where a purchase makes sense for all home video enthusiasts.

Editor Comments Very Evil:

I, like many of my colleagues, have the opinion that DivX was not appreciated in time by DVD player manufacturers and as a result of its slowness and wait-and-see attitude, it was slow to enter the mass market and, according to In the current situation, it completely lost the battle DVD format to inexpensive entry-level DVD players ($ 80-100).

Currently, a two-disc MPEG4 movie with 5.1 sound costs the same retail price in Russia as a single-layer DVD-Video movie ($ 5-6). At the same time, DVDs have no problem changing disc while viewing, player firmware raw, codec version incompatibility, braking, and artifacts while viewing.

My summary is as follows: consumer MPEG4 / DivX players and discs with movies in this format will undoubtedly strengthen their position and occupy their niche in the market, but they will be as widespread in the consumer sphere as DVD-Video players. And consumer discs (based on MPEG-2 video, plus DolbyDigital 5.1 sound) is a very important question, which only time can answer.
