<h1>Kino Export</h1>
<p>Kino allows you to export your
movie, or parts of it, to various
files and devices. This is useful if
you wish to create e.g. a DVD movie
from your project.</p>
<p>You can export to an IEEE 1394
device, render your movie to a DV/AVI
file, export stills or sound, export
to MPEG format or to any program that
accepts RAW DV frames as input.</p>
<p>At the right hand side of the export page, there are a number of tabs, which
are used to select how to export.</p>
<h2><a name='toc'>Table of Contents</a></h2>
<ol>
<li><a href='#1'>Selection of the <b>Frames</b></a></li>
<li><a href='#2'>Exporting to an <b>IEEE 1394</b> device</a></li>
<li><a href='#3'>Exporting to a <b>DV file</b></a></li>
<li><a href='#4'>Exporting <b>Stills</b></a></li>
<li><a href='#5'>Exporting <b>Audio</b></a></li>
<li><a href='#6'>Exporting to <b>MPEG</b> </a></li>
<li><a href='#7'>Exporting to a <b>DV pipe</b></a></li>
<li><a href='#8'>Starting, stopping and pausing export</a></li>
</ol>
<h2>1. <a name=1>Selection of the Frames</a></h2>
<p>You select the frames of your video at the top of the Export page. There are 3 principal ways to select
frames; which one you use is determined by the top drop-down box. The default choice is "All" which will export
all frames in your project. Next choice is "Current" which will export the current frame (probably mostly useful
when exporting stills) and finally there is "From" which allows you to numerically select the first and last frame
to export. You can also select to not export every frame, but e.g. only every second or third frame. You do this by changing
the number in the spinbox. The default is to export every frame.</p>
<p><a href='#toc'>Back to Top</a></p>
<h2>2. <a name=2>Exporting to an IEEE 1394 device</a></h2>
<p>Exporting to an IEEE 1394 device allows you to e.g. export your movie back to
your camera. This page contains a number of parameters that can be tuned to
optimize the export process to your camera. Experimentation with the values
may be required to get the best result.</p>
<p><a href='#toc'>Back to Top</a></p>
<h2>3. <a name=3>Exporting to a DV file</a></h2>
<p>On this tab you can create a DV/AVI file from your project. You need to supply a basename,
which will be the filename stem of any file exported. You also need to set various
parameters that should be more or less self-explanatory.</p>
<p><a href='#toc'>Back to Top</a></p>
<h2>4. <a name=4>Exporting Stills</a></h2>
<p>This tab allows you to export still images. You need to supply a basename with extension. The
extension will determine the format to export. A large number of formats is supported, including
JPG and PNG.</p>
<p>If your source material is
interlaced (as most is) the
<b>Extract</b> option lets you specify
if you want to export the raw frame, upper or lower field or a blend between them.</p>
<p>If you check the "Resample Pixel Aspect"
checkbox, your stills will be
resampled to adjust for the different
pixel aspect ratio between DV frames
and the square pixels of a computer
screen.</p>
<p><a href='#toc'>Back to Top</a></p>
<h2>5. <a name=5>Exporting Audio</a></h2>
<p>The audio export page is pretty straightforward. Choose the sampling rate and the format
from the dropdown boxes (making sure you have the required programs mentioned in parentheses).
If you want a new audio file for each scene, check the "Scene Split" checkbox.</p>
<p><a href='#toc'>Back to Top</a></p>
<h2>6. <a name=6>Exporting to MPEG</a></h2>
<p>On this tab you can create MPEG files in various ways. You need to provide a basename to export to.</p>
<p>This page requires the package
mjpegtools to function. The file
format reflects options in this
program, and you can select between a
number of formats suitable for such
final media as VCD or DVD.</p>
<p>Most of the options are pretty straightforward. The deinterlace option selects how the frames
should be deinterlaced. If you are familiar with the mjpegtools, you can supply your own arguments
to the different programs used during export.</p>
<p>As exporting to MPEG can be a very
lengthy operation, you have the option
of not cleaning up intermediary files
in case some operation goes
wrong. Uncheck the "Cleanup" checkbox
if you want them to persist in case
the multiplex operation goes
wrong. The "Scene Split" checkbox
creates a MPEG file for each
scene.</p>
<h3>Support for DVD</h3>
<p>The "Output dvdauthor XML" checkbox enables generation of an XML file suitable for input to the program dvdauthor.
This will create a very simple DVD directory, which, if burned to a DVD, will play your movie in
a standalone player. To illustrate this, we will present how to make a very simple, but usable, DVD movie. This
requires the program dvdauthor, mkisofs and growisofs (part of dvd+rw-tools)</p>
<p>Start by selecting a frame
range. Next, specify an output file
name, say "/usr/tmp/mydvd". Now select
the format "8 - DVD" from the format
drop-down box. Check the "Output
dvdauthor XML" checkbox. Click the
Export button in the bottom of the
Export page.</p>
<p>Your export should now start. When
it is done (and this can take a very
long time), you should have a file
called "/usr/tmp/mydvd001.mpeg" and a
file called
"/usr/tmp/mydvd-dvdauthor.xml". Now,
open a console, change to /usr/tmp/
and create a directory called mydvd:</p>
<pre>$ cd /usr/tmp
$ mkdir mydvd</pre>
<p>Now you need to run dvdauthor:</p>
<pre>$ dvdauthor -o mydvd -x mydvd-dvdauthor.xml</pre>
<p>You can check the DVD directory
with the program xine:</p>
<pre>$ xine dvd:/usr/tmp/mydvd/VIDEO_TS/</pre>
<p>(Note that it is important to use
the full path.)</p>
<p>Now the directory /usr/tmp/mydvd contains a DVD directory that can be used to
create an iso image from. You can make an iso image with the program mkisofs:</p>
<pre>$ mkisofs -dvd-video -o mydvd.iso mydvd/</pre>
<p>Finally, this program can be burned to a DVD with the program growisofs:</p>
<pre>$ growisofs -dvd-compat -Z /dev/dvd=mydvd.iso</pre>
<p>And the result is a very simple DVD (without menus) that should play in most standalone players.</p>
<p><a href='#toc'>Back to Top</a></p>
<h2>7. <a name=7>Exporting to a DV pipe</a></h2>
<p>This tab allows you to export to a
program that accepts raw DV input. You
need to supply a base name.</p>
<p>The actual export is carried out by a number of scripts that are installed alongside kino. Please
consult these for an explanation of their possibilities.</p>
<p><a href='#toc'>Back to Top</a></p>
<h2>8. <a name=8>Starting, stopping and pausing export</a></h2>
<p>At the bottom of the export page, there are buttons to start, stop and pause the export.</p>
<p>During export, kino will try to estimate the time needed to complete the export, and
display this time in the statusbar. This estimate is often a bit too optimistic in the beginning
of the export process, but will get more accurate later in the process.</p>
<p>If you stop the export, kino will abort the export process. This can lead to temporary
files not being deleted by the programs kino called to perform the export.</p>
<p>Pausing the export can be beneficial if you need to perform other computing and wish to
free the system from the burden of the export process temporarily.</p>
