mvtools

Motion estimation and compensation plugin for Avisynth+ and Avisynth v2.6 family.
Supporting YUY2, 4:2:0, 4:2:2, 4:4:4 at native 8, 10, 12, 14 and 16 bit depths, 32bit float in selected filters.
Still supporting Windows XP. x86 and x64 versions From December 20, 2020: Linux port

Note: For a more experimental feature set (new parameters, use hw devices for motion estimation, but Windows only) have a look at DTL's fork: https://github.com/DTL2020/mvtools

External dependencies:

• libfftw3f-3.dll (or renamed to FFT3W.DLL) from http://www.fftw.org/ or look at ICL builds at http://forum.doom9.org/showthread.php?t=173229 It is used only at specific dct parameter values

• May require Microsoft Visual C++ Redistributables https://www.visualstudio.com/downloads/

• mvtools2, 2.6.0.5 64 bit version from http://avisynth.nl/index.php/AviSynth%2B#AviSynth.2B_x64_plugins

Build Instructions

Note:

Windows MSVC builds are using external assembler source - if there exists.

Other builds are using internal SIMD code, governed by defines in def.h

Windows MSVC

• Prerequisite: for asm compilation use nasm https://www.nasm.us/ Visual Studio integration: https://github.com/ShiftMediaProject/VSNASM/releases

  Compiler nasm.exe can appear in e.g. C:\Program Files\Microsoft Visual Studio\18\Community\VC\

  You can check the files nasm.targets, nasm.props and nasm.xml in e.g. C:\Program Files\Microsoft Visual Studio\18\Community\MSBuild\Microsoft\VC\v170\BuildCustomizations\

  For XP compatible (v141_xp) build, copy them to the v150 BuildCustomizations folder as well: C:\Program Files\Microsoft Visual Studio\18\Community\MSBuild\Microsoft\VC\v150\BuildCustomizations\

  Important for VS2026 + v141_xp: The VSNASM files released for VS2026 use task parameters (TrackFileAccess on GetOutOfDateItems, and AcceptableNonZeroExitCodes, StdOutEncoding, StdErrEncoding, UseMsbuildResourceManager on ParallelCustomBuild/CustomBuild) that are not supported by the older Microsoft.Build.CppTasks.Common.dll (v15.0) shipped with the v150 toolset folder. The v170 copy is fine as-is. In the v150 copy only, remove those attributes from nasm.targets:

  • In both <GetOutOfDateItems> calls: remove TrackFileAccess="$(TrackFileAccess)"
  • In <ParallelCustomBuild>: remove AcceptableNonZeroExitCodes, StdOutEncoding, StdErrEncoding, UseMsbuildResourceManager
  • In <CustomBuild>: remove AcceptableNonZeroExitCodes, StdOutEncoding, StdErrEncoding

  Some nasm versions (e.g. the one valid around 2022.Dec.) will throw a lot of warnings on x265 assembler files. Temporarily they are silenced with -w-macro-params-legacy parameter.

Linux build instructions

• Clone repo

    git clone https://github.com/pinterf/mvtools
    cd mvtools
    cmake -B build -S .
    cmake --build build
  

  Useful hints:
  build after clean:

  cmake --build build --clean-first
  

  delete CMake cache

  rm build/CMakeCache.txt
