    Best Bitrate for divx

    Can anyone relate their experiences with encoding to divx? What settings do you recomend and at what point (BITRATE) do you get the maximum quality for a given resoulution.File size isnt a consideration (quality IS) but I dont want to unneccesarly waste hard drive space. Thanks

    Dowload one of the MANY bitrate calculators available at DivX Digest - link at the top of the page...

      Mabey I should make myself clearer...

      I want to know at what bitrate do you get the highest quality picture.

        To achieve maximum quality, use the 1-pass, Quality-based setting on DivX 4.x/ 5.x configuration, and set it to 100%.

          Why 1 pass? I thought 2 pass was better...?

            In the case of 1-pass, quality setting, the codec will encode the movie at "X"% quality, whose value is manually set by the user. At 100% quality, there really is no need for a 2-pass encoding since the codec will assign the maximum amount of bitrate to saturate every frame in the video.

              Ok I think i get it.Your probably gonna get a much larger file than if you used 2 pass.Mabey like the difference between vbr and constant?

                I haven't personally tested it myself. However, I doubt you can get any bigger than 100% quality, since all the frames have already been saturated. In fact, using 2-pass encoding and assigning ridiculously high bitrate (6000kbps+) will land you at around the same filesize as the 100% quality method.

                Lastly, 100% quality setting will be VBR as well since the codec compresses each frame in the video at the maximum quality. Knowing that different frames compress differently (some have a great deal more info than others), the bitrate distribution will be variable.
