     21OpenDivX or Xvid?
     22
     23OpenDivX is a free implementation of the mpeg4-codec. Alas, the
     24developers at ProjectMayo didn't gratefully release their actual source
     25in compileable versions, so the displeasure of the users majority
     26canalized into a new project named Xvid.
     27
     28Xvid development was interrupted in Autumn 2002 due to a code-theft
     29the developers at Sigma design committed but it is continued now.
     30
     31For worse luck, OpenDivX and Xvid are using the same header file
     32names (an issue that wouldn't be resolved easily) and function
     33namespace, so you'll have to choose which one to use.
     34
     35I personally vote for Xvid, because the installation from sources
     36is much smoother. If you use mencoder and transcode at the same time,
     37you may want to choose different codecs for each.

     104<para>Following features of MPEG-4 are supported:</para>
     105<para><emphasis>I, P Frame encoding</emphasis></para>
     106<para>I-Frames are image frames, while P-Frames are Pattern Frames.
     107Image Frames contain full images. P-Frames contain patterns of what changes in
     108the image, thusly saving a lot of space.</para>

     115<para><emphasis>fullpixel and halfpixel precision</emphasis></para>
     116<para>Even halfpixel movements can be encoded. Better precision
     117results in better compression at better quality.</para>
     118<para><emphasis>both MPEG-4 and H263 quantizations</emphasis></para>
     119<para>MPEG-4 is the standard DivX was derived from. H263 is a
     120slightly changed subset of that standard made by Microsoft. Quantization
     121means to map the quantity of color values to numbers.</para>
     122<para><emphasis>custom quant matrices</emphasis></para>
     123<para>The quantization can be done using custom matrices,
     124possibly giving better results if the matrix is made to suit the video
     125data. Every normal user should be fine with the default matrix that comes
     126with <application>XviD</application>.</para>
     127<para><emphasis>Adaptive quantization / Luminance masking</emphasis></para>
     128<para>Qantization and Luminance masking are variant, depending
     129on the input material, therefore providing better results on dark or very
     130contrasting images.</para>
