'AviUtl 2', which redesigns AviUtl and the extended editing plugin from scratch and supports 64-bit, will be suddenly released after six years

AviUtl , a free video editing software developed by KEN-kun, was developed as a 32-bit application, but there have been no official updates since version 1.10 was released in October 2019. However, on July 7, 2025, AviUtl ExEdit2 beta1 , a beta version of version 2, was released. It has an extended editing plug-in and is compatible with 64-bit versions of Windows 10 and later.

AviUtl is known as a free software that allows advanced video editing, and was especially useful for sites such as NicoNico Douga. However, since it is a 32-bit application, it can only use up to 4GB of memory by default, which can cause memory shortages depending on the project.

In addition, to perform advanced video editing, it is necessary to add various plugins and scripts, including the 'Extended Editing Plugin.' Many of these plugins for AviUtl conflict with each other, but since AviUtl's updates stopped in 2019, users have had no choice but to build up plugins developed by volunteers and customize them according to their environment and purpose.

However, version 2, 'AviUtl ExEdit2 beta1', was suddenly released on July 7, 2025. According to KEN-kun, AviUtl ExEdit2 beta1 is compatible with 64-bit Windows 10 and later and requires an environment that supports DirectX 11.3 and AVX2.

The official website also releases a ZIP file version that does not require installation, an EXE file version of the installer, and a Plugin SDK. This time, click 'aviutl2beta1.zip' to download the ZIP file version that does not require installation. The file size is about 2.2MB.

Extract the downloaded aviutl2beta1.zip file using the standard Windows functions or a tool such as

Explzh . The main application file name is 'aviutl2.exe.' Double-click this aviutl2.exe to launch it.

The default UI of AviUtl ExEdit2 beta1 looks like this. In version 1 of AviUtl, multiple windows were displayed for each function, but this has been integrated into one window, and the overall impression is that the design is more like a modern video editing software.

The newly released AviUtl ExEdit2 beta1 is only a test version, and when I actually used it, I felt that it was a little unstable, such as taking a long time to load and hanging up. Also, although it is compatible with scripts and plugins from version 1, it does not support some plugins and scripts that use 32-bit DLLs, so I hope for a future update.
