+<P><B>MEncoder</B> is capable of creating movies from one or more JPEG or PNG
+ files. With simple framecopy it can create MJPEG (Motion JPEG) or MPNG
+ (Motion PNG) files.</P>
+
+<P><B><I>Explanation of the process</I></B></P>
+
+<P><B>MEncoder</B> <I>decodes</I> the input image(s) with an available MJPEG
+ video codec (when decoding PNGs, it will use the internal PNG decoder). By
+ default it uses <CODE>ffmjpeg</CODE>, so you have to compile with libavcodec
+ support (which is recommended anyways). Its disadvantage is that it can't
+ handle some JPEG types (green image will be encoded for these). Use some
+ external utility to convert those images into edible format.<BR> You can
+ freely choose any other MJPEG decoder, like <CODE>mcmjpg32.dll</CODE>
+ (MainConcept Motion JPEG) if installed, and after checking
+ <CODE>codecs.conf</CODE> and checking the <CODE>videocodec</CODE> line which
+ refers to this file, you'll learn you have to use the <CODE>-vc mjpeg</CODE>
+ option for it.
+</P>
+
+<P><B>MEncoder</B> then feeds the decoded image to the chosen video compressor
+ (DivX4, Xvid, ffmpeg msmpeg4, etc...). Watch for the PNG decoder, as
+ currently it can output only to RGB formats, thus can't be used with codecs
+ that require YUV as input, like DivX4 or ffmpeg's msmpeg4.</P>
+
+<P><B><I>Examples</I></B></P>

+<P>The explanation of the <CODE>-mf</CODE> option can be found below in the
+ global <A HREF=#2.4.5>Options</A> section and in the manpage.</P>
