I tried to use chunk encoding, was generated a script named "tempSceneChangeDetectionVapoursynthFile", with the following code
The problem here, is that for generate the scene-change, is performed the full colorization, while, the scene change should be generated using only the input clip.
In this way cannot be used to speed-up the colorization process.

# adjusting color space from YUV420P8 to RGB24 for vsHAVC
clip = core.resize.Bicubic(clip=clip, format=vs.RGB24, matrix_in_s="709", range_in_s="limited", range_s="full")
# adding colors using HAVC
clip = havc.HAVC_main(clip=clip, Preset="veryslow", ColorModel="Video+Artistic", CombMethod="ChromaBound Adaptive", VideoTune="vivid", ColorTemp="low", ColorFix="retinex/red", FrameInterp=0, ColorMap="red->brown", ColorTune="medium", BlackWhiteTune="light", BlackWhiteMode=0, BlackWhiteBlend=True, EnableDeepEx=False, enable_fp16=True)
# Resizing using 10 - bicubic spline
clip = core.fmtc.resample(clip=clip, kernel="spline16", w=320, h=136, interlaced=False, interlacedd=False) # resolution 320x136 before RGB24 after RGB48
# adjusting color space from RGB48 to YUV420P8 for vsSCXvidFilter
clip = core.resize.Bicubic(clip=clip, format=vs.YUV420P8, matrix_s="709", range_in_s="full", range_s="limited", dither_type="error_diffusion") # additional resize to allow target color sampling

clip.set_output()The problem here, is that for generate the scene-change, is performed the full colorization, while, the scene change should be generated using only the input clip.
