Where to Download AviSynth Builds Listed on the Wiki

Updated

The Avisynth wiki (avisynth.nl) is documentation, not a download host — it links out to the actual download locations. For most users today, the recommended path is AviSynth+, which the wiki lists under "Current Builds" with new features, backward compatibility, and native support for Unix-like operating systems. Download links point to the wiki page, the project homepage at avs-plus.net, and the latest release on GitHub. The older official and unofficial v2.6.0 builds (32-bit ST and MT) are marked Deprecated and are hosted at SourceForge.

Current builds: AviSynth+

The wiki's "Download AviSynth" section separates current from deprecated builds. Under Current Builds it lists AviSynth+ and points to three places:

  • Wiki page — the AviSynth+ documentation page on avisynth.nl
  • Homepage — avs-plus.net
  • Latest release — GitHub releases
  • Discussion — forum.doom9.org

If you want the actively maintained version, start with the GitHub release page or avs-plus.net. The wiki page is where you read about it, not where the binary lives.

Deprecated builds: 2.6.0

The wiki still lists the older builds, but flags them as deprecated:

Build Notes Host
Official v2.6.0 ST 32-bit, single-threaded SourceForge
Unofficial v2.6.0 MT 32-bit, multi-threaded SourceForge

These remain available for legacy scripts or plugins that depend on the 2.6 API, but they are not the version to choose for a new setup.

How to pick

  • New project, modern plugins, or a Unix-like OS → AviSynth+ from GitHub or avs-plus.net.
  • Existing script or plugin that requires the 2.6 API → the deprecated 2.6.0 build from SourceForge, accepting that it is 32-bit and no longer current.
  • Just reading up before installing → the wiki's "New to AviSynth – Start Here" pages (Your first script, Getting started, Grammar, Filter introduction, Script examples, FAQ) are the entry points.

A note on the wiki itself

avisynth.nl is a community-maintained documentation site, hosted since around 2010. The wiki states that hosting costs money and asks for donations via Buy Me a Coffee or PayPal — this is a request to support the site, not a paywall on the software. AviSynth itself is described on the wiki as free open-source software under GPLv2.
