TechIMO presents us a comparison of 11 video codecs. The Moving Picture Expert Group declared MPEG-4 as the new standard over the older MPEG-2. At this moment, there are several MPEG-4 codecs, the most popular of them being DivX. But what quality do they offer? TechIMO found out:
Analysis of compression quality and efficiency is a subjective process. What appears acceptable to one person may not to another. From the graphics presented, it appears that XviD 2-pass is probably the best solution in extremely high bitrate situations. DivX 5 Professional one-pass fairs slightly better than XviD for mid-range bitrates.”
