<p>I'm trying to improve some VHS-C home video recordings for my mother. I used <code>VirtualDub</code> to capture the recordings as avi files and now I wish to modify them with <code>Avisynth</code> but I can't get the frame server function to work. Has anyone got the <code>VirtualDub</code> frame server connection with <code>Avisynth</code> working in Windows 10? </p>

<p>I've tried this with the latest versions of <code>VirtualDub</code>, <code>Avisynth</code>, and both <code>AvsP_v2.0.2</code> with <code>bugfix3</code> and <code>AvsPmod</code>. Also, I've tried it with <code>VirtualDub_1910.exe</code>, <code>Avisynth_258.exe</code>, <code>AVSPluginPack.exe</code> and <code>AvsPmod_205.exe</code> from AnimeMusicVideos.org (<code>AMVapp31.zip</code>). I'm using Windows 10 64-bit however I've only downloaded 32-bit version software and codecs because that seems to be the generally recommended route. (Is the <code>AVSPluginPack</code> necessary? If so, is there somewhere other than AMV that maintains it?)</p>

<p>In VirtualDub, I open <code>homevideo.avi</code>, "Crop to selection" for a desired range of frames and then <code>File &gt; Start frame server...</code> and name the Avi-File Handler <code>video.vdr</code>.</p>

<p>In AvsP and AvsPmod the commands:</p>

<pre><code>video = AVISource("c:\VHSC\video.avs")
return video
</code></pre>

<p>where <code>video.avs</code> is a file that contains only the line <code>AviSource("c:\VHSC\video.vdr")</code></p>

<p>produce the error message:</p>

<pre><code>Avisynth open failure:AVIFileSource: couldn't open file 'c:\VHSC\video.vdr'
(C:\VHSC\video.avs, line 1)
(New File, line 1)
</code></pre>

<p>However, replacing <code>video.avs</code> with <code>homevideo.avi</code> does display the frames in the AvsP/mod window.</p>

<p>I've seen this similar question <a href="https://video.stackexchange.com/questions/24688/avisynth-cant-open-my-avi-file-avisource-couldnt-locate-a-decompressor-for">AviSynth can&#39;t open my AVI file: &quot;AVISource: Couldn&#39;t locate a decompressor for fourcc dvds&quot;</a>.

Did you install the frameserver support with auxsetup.exe? You can test if it is working by trying to open your video.vdr with another instance of virtualdub.exe.

From your description it doesn't look you really need the frameserver. You can trim the video with avs itself (e.g. Trim(100,200)), this is more robust and efficient.

Btw did you know there is active avisynth community on forum.doom9.org, forum.videohelp.com
