<span class="application">MEncoder</span> is capable of creating movies from one
or more JPEG, PNG, TGA, or other image files. With simple framecopy it can
create MJPEG (Motion JPEG), MPNG (Motion PNG) or MTGA (Motion TGA) files.
</p><div class="orderedlist"><p class="title"><b>Explanation of the process:</b></p><ol type="1"><li><p>
<span class="application">MEncoder</span> <span class="emphasis"><em>decodes</em></span> the input
image(s) with <code class="systemitem">libjpeg</code> (when decoding
PNGs, it will use <code class="systemitem">libpng</code>).
</p></li><li><p>
<span class="application">MEncoder</span> then feeds the decoded image to the
chosen video compressor (DivX4, Xvid, FFmpeg msmpeg4, etc.).
</p></li></ol></div><p><b>Examples.聽</b>
The explanation of the <tt class="option">-mf</tt> option is in the man page.
