Description

AviSynth+ plugin to load and apply Adobe 3D LUTs to a clip. DGCube is a CUDA version of the AVSCube filter.

Requirements


Syntax and Parameters

DGCube (clip, string "cube", bool "expand_in", bool "compress_out", string "interp", int "device")


clip   =
Input clip; the filter receives and delivers either RGBP16 or YUV420P16 color space.


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


bool  expand_in = false
Expand the input from limited range to full range. Default is false.


bool  compress_out = false
Compress the output from full range to limited range. Default is false.


string  interp = "tetrahedral"
String specifying the interpolation method: "tetrahedral" (default) or "trilinear".


int  device = 255
GPU device number to use. If device is 255 (default), then the GPU device will be automatically selected.


Examples

Apply 3D LUT to clip obtained from BlankClip:

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

Apply 3D LUT to HDR10 PQ clip obtained from DGSource using internal YUV<->RGB conversions:

# Source
DGSource("THE GREAT WALL.dgi")
# Load and apply "PQ_to_BT709_slope" cube. Input and output is Limited Range YUV420P16 DGCube("PQ_to_BT709_v1.cube", expand_in=true, compress_out=true, interp="tetrahedral")

Apply 3D LUT to HDR10 PQ clip obtained from DGSource using external conversions to RGBP16:

# Source
DGSource("THE GREAT WALL.dgi")
# From 4:2:0 10bit planar Limited Range to RGB Planar 16bit Full Range z_ConvertFormat(pixel_type="RGBP16", colorspace_op="2020:st2084:2020:limited=>rgb:st2084:2020:full", dither_type="error_diffusion")
# Load and apply "PQ_to_BT709_slope" cube DGCube("PQ_to_BT709_v1.cube", expand_in=false, compress_out=false, interp="tetrahedral")
# From RGB 16bit planar Full Range to YUV420 10bit planar Limited Range with dithering z_ConvertFormat(pixel_type="YUV420P10", colorspace_op="rgb:709:709:full=>709:709:709:limited", dither_type="error_diffusion")
