<h2>AVFS<a class="headerlink" href="#avfs" title="Permalink to this heading"></a></h2>
<p>AV FileSystem is based on <a class="reference external" href="https://turtlewar.org/avfs/">AVFS</a> and shares most of its
source code and functionality. This package has several uses. It can easily make
a script file openable by any application, as it appears like a real,
uncompressed avi file. It can also be used to bridge the 32/64 bit gap, since a
plain file can always be read.</p>
<p>To use it simply run <code class="docutils literal notranslate"><span class="pre">avfs</span></code> in the <code class="docutils literal notranslate"><span class="pre">core32</span></code> or <code class="docutils literal notranslate"><span class="pre">core64</span></code> directories with the script name as argument.
This will create a virtual file in <code class="docutils literal notranslate"><span class="pre">C:\\Volumes</span></code>.</p>
<p>The <em>alt_output</em> argument of <em>set_output</em> is respected and can be used to get additional compatibility
with professional applications.</p>
<section id="avisynth-support">
<h3>Avisynth Support<a class="headerlink" href="#avisynth-support" title="Permalink to this heading"></a></h3>
<p>Note that this AVFS version is also compatible with Avisynth 2.6 and Avisynth+. When using Avisynth+
higher bitdepth output is also supported. The easiest way to obtain a recent version is to extract
<code class="docutils literal notranslate"><span class="pre">avfs.exe</span></code> from the portable VapourSynth archives.</p>

<section id="vfw">
<h2>VFW<a class="headerlink" href="#vfw" title="Permalink to this heading"></a></h2>
<p>On windows, you can output video to VFW based programs.</p>
<p>If you install VapourSynth by installer, the VSVFW.dll is registered already</p>
<p>Else, you could register it manually, use register file below or use <a class="reference external" href="https://github.com/theChaosCoder/vapoursynth-portable-FATPACK/blob/master/VapourSynth64Portable/extras/enable_vfw_support.bat">theChaosCoder’s batch</a>.</p>
