VapourSynth Installation for Python 3.6.8

***Before you go any further - this is for Windows installation only.

My ongoing experiments with incorporating the Python-based image processing software, VapourSynth, into my color management and restoration pipeline has resulted in compiling a stable package which Windows users may use for further experimentation. I’m using this package specifically because it has thus far been compatible with Python 3.6.8 thus meeting the compatibility requirements of Davinci Resolve Studio 17.2.

I would also like to credit my friend and colleague Hamid Sadeghi for his Python kung-fu and for helping me with this project.

Basic VapourSynth Script:

This is a basic script for transforming the color primaries of a Rec.601 .avi file which has been captured from a mini-DV archival tape with 4:1:1 chroma subsampling and 8-bit precision into a Rec.709 4:2:2 media file with 10-bit precision. The QTGMC plugin is used to deinterlace and field interpolate. It does a remarkable job bypassing the vertical resolution loss of a standard deinterlacer by interpolating the missing field lines when constructing the progressive frame. The core.resize.Spline36 changes the PAR to 1:1 within a standardized 540 vertical.

import vapoursynth as vs
import havsfunc as haf
core = vs.get_core()
clip = core.ffms2.Source(source='E:\Captured_Archival\\your_video.avi')
clip = vs.core.resize.Point(clip, format = vs.YUV422P10)
clip = haf.QTGMC(clip, Preset='Slower', TFF=False)
clip = core.resize.Spline36(clip, 720, 540)
clip.set_output()
