Description

AviSynth+ plugin to load and apply Adobe 3D LUTs to a clip. Ported from VapourSynth timecube plugin.

Requirements

• AviSynth+ (x86 and x64)
• Supported color formats: RGBP16

Syntax and Parameters

Cube (clip, string "cube", int "cpu", bool "fullrange")

clip   =

Input clip; the filter receives and delivers the RGBP16 color space.

string  cube = ""

Full path of the 3D LUT file. This must be an Adobe *.cube file.

int  cpu = INT_MAX

cpu: default INT_MAX, which selects best SIMD.

• 0 : SIMD_NONE
• 1 : SIMD_SSE42
• 2 : SIMD_AVX2

bool  fullrange = true

• false : limited range
• true : full range

Examples

Apply 3D LUT to clip obtained from BlankClip:

BlankClip(pixel_type="RGBP16", color=$ff0000)
Cube("...\test.cube")
ConvertToYUV420()

Apply 3D LUT to HDR10 PQ clip obtained from DGSource() to go to HLG:

#Indexing
DGSource("THE GREAT WALL.dgi")
#From 4:2:0 10bit planar Narrow Range to RGB Planar 16bit Full Range
z_ConvertFormat(pixel_type="RGBP16", colorspace_op="2020:st2084:2020:limited=>rgb:st2084:2020:full", resample_filter_uv="spline64", dither_type="error_diffusion")

#From PQ to HLG with 16bit precision
Cube("...\test.cube")

#From RGB 16bit planar Full Range to YUV420 10bit planar Narrow Range with dithering
z_ConvertFormat(pixel_type="YUV420P10", colorspace_op="rgb:std-b67:2020:full=>2020:std-b67:2020:limited", resample_filter_uv="spline64", dither_type="error_diffusion")
