Welcome to the StaxRip wiki!

You will find various information and documentation about StaxRip here.

If you are new to StaxRip or video encoding, you can get started with an extensive beginner-friendly tutorial.

StaxRip is a versatile video encoding GUI for Windows. It executes and controls console apps like x265, NVEnc, mkvmerge, ffmpeg, etc. and uses the scripting based frameservers, AviSynth+ and VapourSynth, for video processing.

• Support for a wide variety of formats and tools
• All popular and modern video encoders like x265 and NVEnc are supported
• Hardware encoding for AMD, Intel, and Nvidia
• Batch Processing
• Video editing using AviSynth+ and VapourSynth, direct control of the script and popular filters like QTGMC included
• Scriptable via PowerShell
• Minimal user interaction required due to rich configuration and automation features
• Copy modes for audio and video for plain remuxing
• Cut/Trim feature, for MKV output no re-encoding is required
• High DPI scaling
• Dark Mode, Themes
• Portable, nothing has to be installed
• Parallel Job processing, parallel audio video processing, parallel chunk encoding for x265 and aomenc

It's important to understand that x64 and x86 can never be mixed. Everything StaxRip requires and everything it uses is x64. x86 plugins generally don't work in x64 applications.

• Windows 7 x64 is the minimum required Windows version. (*)
• Windows 10 x64 is RECOMMENDED, and necessary since version 2.5.0 if you want to use VapourSynth. Still, you can use VapourSynth R52 with Python 3.8.x in StaxRip on Windows 7 if you manually install them following these instructions. But user discretion is required in that case.
• A CPU supporting at least AVX2 instruction set for some plugins to work: However, StaxRip can be manually backwards-extended to non-AVX2 processors with a workaround. See this page in the Guides section.
• .NET Framework is required in version 4.8.1
• Visual C++ 2022 x64 with minimum version 14.30.30401.

(*) Please note, that MKVToolNix supports Windows 7 only until v64.0, so you have to downgrade yourself.

StaxRip is a portable application, meaning that it has no installer. You only need to extract StaxRip's folder from the downloaded archive, using 7-zip or any archiver compatible with the 7-zip 7z format. Once the folder is extracted, run the StaxRip.exe file.

StaxRip includes portable versions of AviSynth+, VapourSynth, and Python. Therefore, installation of these tools is not required.

Hardware encoding works only on relatively recent hardware and up-to-date drivers.

It's not possible to start StaxRip from a location without full write access.

First setup step is to select a proper scaling value for the User Interface:

• Main Window > Menu Tools > Settings > User Interface: set Scale Factor.

Default value is 1, but on FHD displays, some people prefer 1.15 or 1.20.

Also, in this same Settings menu, you are able to select a variety of dark themes for StaxRip.

Many other settings are available. However, please do not change any of them unless you are an advanced user.

Last but not least, don't forget to make sure that your Windows supports long file path: paths that are longer than 260 characters. See this document for more detail.

VB.NET and the StaxRip codebase are suitable for learning how to program. VB.NET has an intuitive syntax, it's very similar to C#, only the syntax is different.

This is a boring but important task suitable for somebody learning to program.

This is an extremely ambitious goal but generally not impossibly using:

• C#
• Avalonia which is a mature and popular XAML based UI framework
• .NET Core also known as .NET 5
