vs-masktools aims to provide tools and functions to manage, create, and manipulate masks in VapourSynth.
For support you can check out the JET Discord server.
vs-masktools is available on PyPi and can be installed with this simple command:
pip install vsmasktools
The only hard dependencies are vstools and an installation of VapourSynth R59 or higher. However, for full functionality, you should make sure to also install TCanny, TEdgeMask, AWarpSharp2 and AWarpSharp2SF.
