What Is an .avs File and How to Open It

Want to know what the AVS file you have is? This article will explain the AVS file format in detail, including its definition and how to open the AVS file.

An AVS file is most likely an AVS Preset file by Nullsoft for Advanced Visualization Studio (AVS). It’s a profile for animations that you can open in Winamp using the Advanced Visualization Studio plugin.

AviSynth also creates scripts using the .avs file extension. These AVS scripts are text files that contain references and instructions that help AvisSynth edit and process video files more smoothly.

The two types of AVS files mentioned above are usually several kilobytes in file size.

If your AVS file is relatively large, such as a few megabytes to a few hundred megabytes, it may be a video file from Argonaut Games, Audio Video coding Standard Workgroup of China, or a CCTV camera file.

Argonaut Games developed AVS as a game video format for the Creature Shock game. However, it’s an outdated format and few programs can open it now.

AVS may also be a video file created by the Audio Video coding Standard Workgroup of China. Such files are essentially MPEG-PS videos and can contain high-quality video.

Some CCTV cameras may use the .AVS proprietary file format to encode security footage. It will most likely be encrypted, so you will need to open it using software produced by the CCTV manufacturer.

As mentioned above, AVS can be many things. The way to open it is therefore different:

• Open Nullsoft AVS file: You need to install the Advanced Visualization Studio plugin in Nullsoft Winamp to open the AVS file.
• Open AviSynth AVS file: You can open this AVS file in AviSynth or any text file viewer, such as Notepad.
• Open AVS game file: You can try to open the AVS game file in MPV player.
• Open China AVS file: You can try to open the China AVS file in MPV player.
• Open CCTV AVS file: Since it can be encrypted, the only way to open it is to use the accompanied software made by the manufacturer that developed that CCTV.

If you want to edit or share the AVS video on other platforms, it’s best to convert the AVS video to a common format like MP4.

While most programs don’t support this type of file, WonderFox HD Video Converter Factory Pro is an exception. With excellent format support, it can play and convert AVS files (unencrypted) without issues.
