	<h1>Avisynth</h1>

<h2>Why transcode?</h2>

<p>You may think why bother with transcoding when muxing is
		available. That is absolutely right in most cases. But there are some
		video files which can't be muxed because of special conditions. For
		example, you may get a trailer with h.264 video codec and AVC level
		5.1. but your playback device (PS3, Xbox, TV) might not support that.
		In that case you will need transcoding.</p>

<p>You can see that there are some reasons why people want to
		optimize transcoding. On the Windows platform there is an additional
		method available for transcoding.</p>

<h2>Avisynth</h2>

<p>
		<a title="Avisynth" href="http://en.wikipedia.org/wiki/Avisynth">Avisynth</a>
		is a frame server for free, available on Windows platform (development
		of the Linux version will not be continued). Regarding PMS readme one
		should install <a title="Avisynth 2.5.7"
			href="http://sourceforge.net/projects/avisynth2/files/AviSynth%202.5/AviSynth%202.5.7/Avisynth_257.exe/download">Avisynth
			2.5.7</a>. Latest Avisynth 2.5.8 seems to cause stuttering on certain
		files.
	</p>

<h3>VSfilter</h3>

<p>
		After installing Avisynth you also have to install the plugin
		vsfilter. <a title="VSfilter Avisynth"
			href="http://sourceforge.net/project/showfiles.php?group_id=82303&amp;package_id=84359">Download
			it here</a>. You have to decompress the 7z-file and copy the vsfilter.dll
		from unicode-subdirectory to your Avisynth plugin directory
		(C:\program files\AviSynth 2.5\plugins).
	</p>

<h3>Decoding with ffdshow</h3>

<p>
		Transcoding means decoding the video in the first step on the PC and
		in the second step encoding it to MPG2 and streaming it to your PS3.
		For decoding the free software <a title="ffdshow"
			href="http://en.wikipedia.org/wiki/Ffdshow">ffdshow</a> is commonly
		being used. In order to demux container formats ffdshow needs the free
		<a title="Haali Media Splitter"
			href="http://en.wikipedia.org/wiki/Haali_Media_Splitter">Haali
			Media Splitter</a>. Both software are avialable as software packages, so
		called codec packs.
	</p>

<h3>K-Lite Mega Codec Pack</h3>

<p>
		Who wants to get an "everything included" package should consider
		K-Lite Mega Codec Pack which is available <a
			title="K-Lite Mega Codec Pack"
			href="http://www.codecguide.com/download_mega.htm">here</a>. There
		are different variants available, from basic to mega but also a 64-bit
		variant.
	</p>

<p>After installing k-lite codec pack you may have to configure
		subtitles and your speaker setup.</p>

<p>Change to Windows Start menu "programs &gt; K-Lite Codec Pack
		&gt; Configuration &gt; ffdshow audio decoder". In menu "mixer" you
		have to set your speaker config. In order to get 5.1 surround sound
		(speakers: 4x surround, 1x center, 1x subwoofer) on your PS3 you have
		to set "3/0/2 - 5 channels".</p>

<p>After that run "programs &gt; K-Lite Codec Pack &gt;
		Configuration &gt;Haali Media Splitter" and change to options tab.
		Choose menu "languages" and select your language priority:</p>

<ul>
		<li>Audio language priority: ger,eng</li>
		<li>Subtitle language priority: ger,eng</li>
		<li>audio and subtitle languages: ger,off;eng,ger;*,ger;*,eng</li>
		<li>Trackset languages: ger,eng</li>
		<li>The example above is optimized for German language. Here is
			an example for English language:</li>
		<li>Audio language priority: eng</li>
		<li>Subtitle language priority: eng</li>
		<li>audio and subtitle languages: eng,off;*,eng</li>
		<li>Trackset languages: eng</li>
	</ul>

<p>The settings above are only valid when the avisynth video engine
		is used for transcoding.</p>
	<p>Go to menu compatibility and set "autoload VSFilter" to "Yes".</p>

<h3>CCCP Codec Pack</h3>

<p>
		For those who prefer minimal installations <a title="CCCP Codec Pack"
			href="http://www.cccp-project.net/">CCCP codec pack</a> is the right
		choice. It is available <a title="Download CCCP Codec Pack"
			href="http://www.cccp-project.net/download.php?type=cccp">here</a>.
		Read <a title="CCCP Codec Pack FAQ"
			href="http://www.cccp-project.net/wiki/index.php?title=FAQ">FAQ</a>
		for configuration. It should be similar to setup k-lite codec pack.
	</p>

<h2>activate Avisynth-engine</h2>

<p>After installing and configuring Avisynth, ffdshow and Haali
		media splitter you can enable both engines Anisynth/MEncoder and
		Avisynth/ffmpeg.</p>
