It should be noted that even if you only have audio or only have video rendered, a paste <a class="twikiLink" href="../../view/Cinelerra/InsertionStrategy">Insertion Strategy</a> will behave like a normal paste operation, erasing any selected region of the timeline and pasting just the data that was rendered. If you render only audio and have some video tracks armed, the video tracks will get truncated while the audio output is pasted into the audio tracks.

Note:
<p />
Current ffmpeg export pipe does MPEG-PS (Program Stream) and mplex cannot process that. By adding -f mpeg2video before the output file, ffmpeg produces MPEG-ES (Elementary Stream) which can be processed by mplex.
<p />
I used the following:
<p />
ffmpeg -f yuv4mpegpipe -i - -y -target dvd -ilme -ildct -hq -f mpeg2video
<p />
-hq means High Quality (don't really know the details but I trust it produces better quality <img src="../../../pub/TWiki/SmiliesPlugin/biggrin.gif" alt="big grin" title="big grin" border="0" /> )
<p />
-ilme and -ildct are for interlaced processing (I think -ilme is for motion estimation, about -ildct I'm not sure but they both should help producing better quality when doing interlaced encoding, which I prefer since I don't want to loose half of the motion information and DVD stores the video as interlaced anyway)

Rendering takes a section of the timeline, performs all the editing, effects and compositing, and stores it in a pure movie file. You can then delete all the source assets, play the rendered file in a movie player, or bring it back into Cinelerra for more editing. It's very difficult to retouch any editing decisions in the pure movie file, however, so keep the original assets and XML file around several days after you render it.

The mpeg2enc code in cinelerra is 5 years old and has two main problems.  The first is that it is <em>slow</em>.  On my system (a 1.7 GHz pentium4), mpeg encoding takes 6-10 times the length of the original footage.  A 15 minute video takes 2 and a half hours to render on average.  The second is that different video sources cause unpredictable results when your end target is a DVD.  For example, a quantization of 10 may work beautifully for one video, but another video requires a quantization of 16 in order to mplex properly.  Be prepared to experiment a lot to get good DVD video.
<p />
I was excited to learn there is a better solution already in place in the <a class="twikiLink" href="../../view/Cinelerra/CVS">CVS</a> version of cinelerra that should make it into the 1.2.2 or 1.2.3 release.  Follow the steps above, but choose the <code>yuv4mpeg</code> format instead.  Hit the wrench button and choose the ffmpeg DVD preset on the bottom right.  This takes somewhat less than 2 times real time to render a video on my system.  A 15 minute clip takes an average of 25 minutes to render.  I'm hoping to cut it down to almost real time by employing my  laptop as a renderfarm node.

Rendering takes a section of the timeline, performs all the editing, effects and compositing, and stores it in a pure movie file. You can then delete all the source assets, play the rendered file in a movie player, or bring it back into Cinelerra for more editing. It's very difficult to retouch any editing decisions in the pure movie file, however, so keep the original assets and XML file around several days after you render it.

<p />
Quick notes for the lazy.
<p />
What to do to create some DVD content:
<ul>
<li> Have your audio at 48kHz.
</li>
<li> Prepare your video and audio tracks, put your effets in, etc.. Once everything is ready:
</li>
<li> Render the video: <code>Edit/Select All</code>. Hit the <code>[ ]</code> in-out points. <code>Edit/Render</code>
</li>
<li> Choose a filename, put the extension .mpv (so you know it's the video)
</li>
<li> Choose <code>MPEG Video</code> format
</li>
<li> Select the checkbox to render only VIDEO
</li>
<li> Hit the wrench button, select MPEG-2 as 'Derivative'
</li>
<li> You can leave the settings as is (Mine are: Quantization: 15, Fixed quantization <strong>checked</strong>, I frame distance: 45, Color model: YUV 4:2:0, Progressive frames <strong>unchecked</strong>, Denoise <strong>checked</strong>, Sequence start codes.. <strong>unchecked</strong>)
</li>
<li> Start the rendering.. this takes time.
</li>
</ul>
<p />
Note: I had troubles rendering the video part, and found the cause to be mpeg2enc. It needed a predefined aspect ratio from:
<pre>
Display aspect ratio codes:
 1 - 1:1 pixels
 2 - 4:3 display
 3 - 16:9 display
 4 - 2.21:1 display
</pre>
<p />
Once I switch the project to 4:3 .. it started rendering normally. Otherwise, it would just hang there, doing nothing.
<p />
Then the audio part:
<ul>
<li> Select all again, hit <code>File/Render</code>
</li>
<li> Choose the filename, change the extension to .mpa (audio)
</li>
<li> Choose MPEG Audio file format.
</li>
<li> Hit the wrench, select layer: II, 384 kbits.
</li>
<li> Go ! Render
</li>
</ul>
<p />
Now you need to mplex or tcmplex to join the two files.
<ul>
<li> <verbatim>mplex -v 0 -f 8 &lt;video.mpv&gt; &lt;audio.mpa&gt; -o &lt;videoaudio.mpeg&gt;</verbatim>
<ul>
<li> <code>-v 0</code> means verbose: warnings and errors only
</li>
<li> <code>-f 8</code> means: format DVD  (with  NAV sectors) (read <code>man mplex</code> for more details and other formats)
   or
</li>
</ul>
</li>
<li> <verbatim>tcmplex -i &lt;video.mpv&gt; -p &lt;audio.mpa&gt; -o &lt;videoaudio.mpeg&gt; -m d</verbatim>
<ul>
<li> <code>-m d</code> means: DVD format (read <code>tcmplex --help</code> for more details)
</li>
</ul>
</li>
</ul>
<p />
You now have a nice .mpeg file ready to be burned on a DVD (and perhaps a CD with the structure of a DVD ?)

Rendering takes a section of the timeline, performs all the editing, effects and compositing, and stores it in a pure movie file. You can then delete all the source assets, play the rendered file in a movie player, or bring it back into Cinelerra for more editing. It's very difficult to retouch any editing decisions in the pure movie file, however, so keep the original assets and XML file around several days after you render it.
<p />
All rendering operations are based on a region of the timeling to be rendered. You need to define this region of the timeline. The navigation section describes methods of defining regions. See NAVIGATING THE PROJECT. The rendering functions define the region based on a set of rules. When a region is highlighted or in/out points are set, the affected region is rendered. When no region is highlighted, everything after the insertion point is rendered. Merely by positioning the insertion point at the beginning of a track and unsetting all in/out points, the entire track is rendered. 
<p />

When using the renderfarm, Create new file at each label causes one renderfarm job to be created at every label instead of using the internal load balancing algorithm to space jobs.
<p />
When Create new file at each label is selected, a new filename is created for every output file. If the filename given in the render dialog has a 2 digit number in it, the 2 digit number is overwritten with a different incremental number for every output file. If no 2 digit number is given, Cinelerra automatically concatenates a number to the end of the given filename for every output file.
<p />
In the filename /hmov/track01.wav the 01 would be overwritten for every output file. The filename /hmov/track.wav; however, would become /hmov/track.wav001 and so on and so forth. Filename regeneration is only used when either renderfarm mode is active or creating new files for every label is active.
<p />
Finally the render dialog lets you select an <a class="twikiLink" href="../../view/Cinelerra/InsertionStrategy">InsertionStrategy</a>. The insertion modes are the same as with loading files.
