    AVI amd MPEG

    Just to understand: Why an AVI format 1 CD take 2 cd's when we convert it to MPEG?
    Divx is not new compress replace MPEG?

    Simply put, DivX can achieve a better compression rate than can MPEG-1 and hence the reason why there are many DIvX movies that take up only a single CD, compared to VCDs commonly requiring 2 or more CDs.

      AVI, when it contains Divx, and Divx is actually MPEG-4, has a higher compressability than MPEG-1 or MPEG-2. That means with the same bitrate, and therefore the same space, you get better quality. Or for the same quality you can use a lower bitrate thus you need less space. And there is another reason. If you create a standard VCD or SVCD you are restricted in bitrate for video and audio. A VCD i.e. requires a video bitrate of 1150kb/s and a audio bitrate of 224kb/s. This results in max. 75mins of content on a 700MB CD Rom.

        Ok, Thanks.
        So if I get it, when I convert it for SVCD-for able to use it on my DVD, I convert it to Mpeg-2, that y it take 2 CD instead of 1 AVI Divx?

          mpeg is measured in time not space like avi.

                If you want to know details on how to convert to and from MPEG-1/2 visit the site:
                Video forums, video software downloads, guides, blu-ray players and media.

                There you'll find everything you need.
