<h3>Let <em>Niels</em> explain nature</h3>
|
|
<hr />
|
|
<p>What is nature? How did the world end up being what it is today?
|
|
Why do elfs generally not appear before humans?</p>
|
|
<p>These questions are difficult to answer; they, like many other
|
|
nature-related questions, require much thinking, theorizing and
|
|
brainwashing to answer. Even the greatest philosophers will never be
|
|
able to come with a definite answer to such complex questions. Not
|
|
even <em>Niels</em> is able to explain it.</p>
|
|
<h2>Nature + Niels = Truth</h2>
|
|
<p>So, who is this <em>Niels</em>? And what about this <em>nature</em>
|
|
-- what is it really? Well, <em>Niels</em> is a person,
|
|
and <em>nature</em> is where Niels records his films -- his films
|
|
about nature. So far he has recorded three films in the nature, each
|
|
one with a specific and quite relevant theme.</p>
|
|
<p>So, basically, "Niels' nature" is a TV show -- except that it is
|
|
more likely to be played on a computer.</p> <hr />

|
|
<h1>The eps</h1>
|
|
<p>Niels has currently produced 3 episodes, of which currently only
|
|
the third (i.e. the newest) is online. This will change at some point,
|
|
though it is unclear when.</p>
|
|
<p>In all of the three episodes Niels talks as he walks. He talks
|
|
about trees, Bigfeet, local warming and bamboos.</p>
|
|
<p>Niels speaks Danish, so these episodes are also in Danish. As
|
|
Danish isn't a widely understood language, Niels subtitles his
|
|
episodes. For now, only the third episode has been subbed, and it has
|
|
only been subbed in English. If someone volunteers to sub an episode
|
|
in another language, Niels will gladly accept. Niels can be contacted
|
|
at <a href='mailto:ns@metanohi.org'>ns@metanohi.org</a>.</p>
|
|
<p>Note that all of the episodes are licensed under CC BY-SA,
|
|
a <em>free</em> license. Read more about this on
|

the <a href='#details'>Details</a> page.</p> <hr />
|
|
<h3>How to watch</h3>
|
|
<p>If you're using a modern web browser, there's a chance you'll be
|
|
able to simply click on the image of an episode and then watch that
|
|
episode inside your browser. If you're unable to do that, or if you
|
|
don't want to do that, you can always just download an episode for
|
|
offline watching -- just click on the download links.</p>
|
|
<p>The videos last between 25 and 35 minutes each and are encoded into
|
|
the <a href='http://www.xiph.org/'>OGG</a> format,
|
|
using <a href='http://www.theora.org/'>Theora</a> for video
|
|
and <a href='http://www.vorbis.com/setup/'>Vorbis</a> for sound. You
|
|
can read more about this on the <a href='#details'>Details</a>

<h1>How/why/what..</h1>
|
|
<p>It has not been a simple task to arrive at this point. Filming,
|
|
directing, encoding, planning, thinking.. All very difficult things to
|
|
do. This page will attempt to give detailed explanations of various
|
|
semicomplex.. things.</p>
|
|
|
|
<h2>Nature</h2>
|
|
<p>The films take place in the nature. That's it.</p>
|
|
|
|
<h2>License, copyright</h2>
|
|
<p><i><b>Copyright</b></i> --
|
|
see <a href='http://en.wikipedia.org/wiki/Copyright'>Wikipedia's
|
|
article</a> for an explanation -- has reached a level where only a few
|
|
people have that right. Looking at an ordinary film, a piece of music
|
|
or even a computer program, it it often <i>illegal</i> to simply copy
|
|
it. If a person has used up 5MB of their hard disk for a piece of
|
|
music and then chooses to copy it, so that it takes up 5MB on a
|
|
friend's hard disk, there's a high risk that person is doing something
|
|
illegal, because if the music is covered by a heavy copyright (like a
|
|
lot of films, music, books, etc. are), only the ones who reserve the
|
|
right to copy it may copy it. This might work okay when the copyright
|
|
holders only reinforce their right to copy a work in commercial
|
|
contexts, but when they start to restrict ordinary people from simply
|
|
sharing art, it's gone too far.</p>
|
|
<p>So..</p>
|
|
<p>"Niels' nature" episodes are <em>free</em>, in the sense that
|
|
everybody is allowed to share them. As a bonus, everybody is also
|
|
allowed to modify them and share their modifications, so that even
|
|
more people can benefit. All this is made possible by

<h3>"Why not just YouTube?"</h3>
|
|
<p>YouTube still mainly uses H.264 for their videos. It may be that it
|
|
is technically a good codec, but patent-wise it's a mess. That's
|
|
why it's a good thing that YouTube is beginning to use WebM with
|
|
VP8, as that is a free format. It is however still most common
|
|
with Flash-based video players (instead of HTML5-based), and
|
|
considering that Flash can only be perfectly run by the
|
|
proprietary Adobe Flash, it's a problem. Gnash, a free Flash
|
|
player, seems to be steadily solving this problem, but even if it
|
|
eventually becomes capable of running Flash programs perfectly,
|
|
the Flash programs may still not be free. And they should.</p>
|
|
<p>It seems that YouTube uses some non-trivial, non-free JavaScript as
|
|
well as a non-free core only partly available through an API. This
|
|
is a problem. YouTube also has ads, which is annoying. One's use
|
|
of YouTube is in typical Google-way probably not very private
|
|
(see <a href='http://www.youtube.com/t/privacy'>http://www.youtube.com/t/privacy</a>).</p>

<h2>How to play the episodes</h2>
|
|
<p>If you're using a fairly new browser, it should be possible to play
|
|
the episodes inside your browser. They are embedded using
|
|
the <a href='http://en.wikipedia.org/wiki/Use_of_Ogg_formats_in_HTML5'><code><video></code></a>
|
|
tag of HTML5, which is supported in Firefox 3.5+ as well as other
|
|
browsers. As a fallback,
|
|
the <a href='http://www.theora.org/cortado/'>Cortado</a> Java player
|
|
is used. Subtitles are unlikely to work with Cortado, because it's an
|
|
applet.</p>
|
|
<p>If playing the episodes directly in the browser doesn't work, or if
|
|
you simply don't want to do that, just download the episodes and watch
|
|
them in your favourite media player.</p>
|
|
|
|
<h2>This website</h2>
|
|
<p>Apart from using the <code><video></code> tag, this website
|
|
also uses other new additions to HTML. On browsers that support it
|
|
(Firefox 3.5+, GNU IceCat 3.5+, etc.), the background features an SVG
|
|
image (<a href='img/bgflow.svg'>bgflow.svg</a>) and transparency as
|
|
well as other new CSS things are used at various places. All of this
|
|
is nothing but eyecandy, and if it doesn't work because of a browser
|
|
that doesn't support it, fear not! The site should still work just
|
|
fine. It also works just fine without the JavaScript code. It seems to
|
|
work ok in Lynx, anyway.</p>
|
|
<p>I'm using a special font called "Domestic Manners" in some areas of
|
|
the website (it might not show on all browsers). According
|
|
to <a href='http://www.fontspace.com/cheapskate-fonts/domestic-manners'>this
|
|
site</a>, the font
|
|
is <a href='http://www.gnu.org/licenses/gpl.html'>GPL</a>'d, though it
|
|
doesn't state what version of the GPL it's under.</p>

<h2>Denmark</h2>
|
|
<p>Denmark is a small, cold country.</p>
|
|
|
|
<h2>Niels</h2>
|
|
<p>My name is Niels Serup, and I created these films. I live next to a
|
|
forest. <a href='http://metanohi.org/aboutme/'>Read more about
|
|
me.</a></p>
|
|
|
|
<h2>Editing and encoding</h2>
|
|
<p>Creating a nice-looking film can be difficult, especially if you
|
|
want to make it look professional. Using a slow, old computer doesn't
|
|
make things easier. I did manage it, however.</p>
|
|
<h3>Editing</h3>
|
|
<p>For my third episode I thought to myself that it could be nice to
|
|
do a bit of cutting. I
|
|
found <a href='http://www.pitivi.org/'>PiTiVi</a>. While still in
|
|
its early fases, I found it to be very easy to work with.</p>
|
|
<h3>Encoding</h3>
|
|
<p>PiTiVi can also be used to render one's video, but it mysteriously
|
|
kept crashing and stopping at odd times on my computer. While looking
|
|
for help, I noticed that <a href='http://www.kinodv.org/'>Kino</a>
|
|
didn't have any rendering problems. To make Kino render render my
|
|
PiTiVi file, I created a converter. The two programs use different
|
|
file formats for saving data, so it was necessary. You can download
|
|
it <a href='http://metanohi.org/projects/various/pitivi-smil.tgz'>here</a>.</p>
|
|
<p>To convert my films to OGG I
|
|
use <a href='http://en.flossmanuals.net/ffmpeg2theora'><code>ffmpeg2theora</code></a>. Something
|
|
like this:</p>
|
|
<code>
|
|
ffmpeg2theora -o niels-naturX-small.ogv --deinterlace --optimize -v 4 -a 4 -x 448 -y 360 --aspect 16:9 --artist "Niels Serup" --title "Niels' nature X: Y" --date "2009-12-19" --location "Northern Denmark" --copyright "20XX Niels Serup" --license "CC BY-SA (http://creativecommons.org/licenses/by-sa/3.0/)" niels-naturX.dv
