<span class="application">MEncoder</span> can create MPEG (MPEG-PS) format output
files.
Usually, when you are using MPEG-1 or MPEG-2 video, it is because you are
encoding for a constrained format such as SVCD, VCD, or DVD.
The specific requirements for these formats are explained in the
<a class="link" href="menc-feat-vcd-dvd.html" title="11.8. Using MEncoder to create VCD/SVCD/DVD-compliant files"> VCD and DVD creation guide</a>
section.
</p><p>
To change <span class="application">MEncoder</span>'s output file format,
use the <tt class="option">-of mpeg</tt> option.
</p><div class="informalexample"><p>
Example:
</p><pre class="screen">
mencoder <em class="replaceable"><code>input.avi</code></em> -of mpeg -ovc lavc -lavcopts vcodec=mpeg1video \
-oac copy <em class="replaceable"><code>other_options</code></em> -o <em class="replaceable"><code>output.mpg</code></em>
</pre><p>
Creating an MPEG-1 file suitable to be played on systems with minimal
multimedia support, such as default Windows installs:
</p><pre class="screen">
mencoder <em class="replaceable"><code>input.avi</code></em> -of mpeg -mpegopts format=mpeg1:tsaf:muxrate=2000 \
-o <em class="replaceable"><code>output.mpg</code></em> -oac lavc -lavcopts acodec=mp2:abitrate=224 -ovc lavc \
-lavcopts vcodec=mpeg1video:vbitrate=1152:keyint=15:mbd=2:aspect=4/3
</pre><p>
Same, but using <code class="systemitem">libavformat</code> MPEG muxer:
</p><pre class="screen">
mencoder <em class="replaceable"><code>input.avi</code></em> -o <em class="replaceable"><code>VCD.mpg</code></em> -ofps 25 -vf scale=352:288,harddup -of lavf \
-lavfopts format=mpg -oac lavc -lavcopts acodec=mp2:abitrate=224 -ovc lavc \
-lavcopts vcodec=mpeg1video:vrc_buf_size=327:keyint=15:vrc_maxrate=1152:vbitrate=1152:vmax_b_frames=0
</pre><p>

If for some reason the video quality of the second pass did not
satisfy you, you may re-run your video encode with a different target
bitrate, provided that you saved the statistics file of the previous
pass.
This is possible because the statistics file's primary goal is to
record the complexity of each frame, which doesn't depend heavily on
bitrate. You should note, though, that you'll get the best results if
all passes are run with target bitrates that do not differ very much.
