Avisynth Premiere import plugin

The Avisynth Premiere import plugin allows you to open AVS scripts and VDR signpost files in Premiere 5.0 or later. Of course, most of Avisynth's filters are redundant if you're already editing with Premiere, but you may find OpenDMLSource and DirectShowSource useful. Additionally, I've heard that BilinearResize and BicubicResize produce better-quality output than Premiere's built-in resizing.

To install the import plugin, download this archive (~6K) and extract the IM-Avisynth.prm file into your Premiere "Plug-ins" directory. Once it's installed, you should be able to open an AVS or VDR file the way you would any other video file. The source code for the plugin is included in the Avisynth source code distribution on the main page.

Many people have been having problems getting this filter to work. In particular, resizing imported AVS files does not seem to work. You may be able to work around this by resizing to the final size in the AVS script instead of in Premiere.

Avisynth Premiere export plugin

The Avisynth Premiere export plugin makes it possible to use Premiere (5.0 or later) as a frame server similar to VirtualDub's. You can connect to the frame server from an Avisynth script with the IPCSource filter, whereupon Premiere's output becomes available as an Avisynth clip. This allows you to export from Premiere to any application which can read AVS files, such as VirtualDub or TMPGEnc.

To install the export plugin, download this archive (~6K, same as above) and extract the CM-Avisynth.prm file into your Premiere "Plug-ins" directory. The source code for the plugin is included in the Avisynth source code distribution on the main page.

To use the export plugin, follow these steps:

  1. Export your movie and choose "Link to Avisynth" as the file type.
  2. Enter a dummy file name for the movie. This file will not be created, but will be used as an identifier for the server. It doesn't matter what directory you "save" it in.
  3. Click Save, and a little window should pop up which says, "Now serving. To connect from Avisynth use the following command..."
  4. Copy the command to the clipboard and paste it into a new text document. Save the document with a .AVS extension.
  5. Open this file in any application which supports AVS files (see the supported applications page).
If IPCSource gives you an "audio misalignment" error, please email me with the version of Premiere you're using, the frame rate of the video, and the sample rate and format of the audio you're trying to export. If you have other problems, email me and let me know. As a workaround for the audio misalignment problem, you can export your sound track to a separate WAV file and then use Avisynth's WAVSource and AudioDub filters in the AVS script to dub it back in.
