OCIOFileTransform

使用OpenColorIO库从文件(通常是1D或3D LUT)加载色彩空间转换并应用它。您还可以加载其他基于文件的转换,例如ASC ColorCorrection XML。文件转换的应用无需任何输入或输出色彩空间的处理。如果文件需要对数编码的像素,但是将节点应用于线性图像,则会得到不正确的结果。OCIOFileTransform节点基于OpenColorIO库。

图像序列接收色彩空间转换。

面具

用作遮罩的可选图像。默认情况下,颜色空间转换仅限于蒙版的非黑色区域。

首先,遮罩输入在节点的右侧显示为三角形,但是当您拖动它时,它会变成标记为箭头的箭头mask。如果看不到遮罩输入,请确保mask控件被禁用或设置为none

注意:  FilmLight and Foundry have elected to no longer bundle Truelight as of Nuke 11. The Truelight node has been superseded by the free version of Baselight for Nuke which itself can import a BLG (Baselight Linked Grade) that can contain a Truelight strip, plus optionally a lot more in terms of creative grading intent. Together with OpenColorIO and the native Nuke Vectorfield node we feel all the Nuke color management issues for which the Truelight node was originally intended are now addressed.

指定插值方法。如果所使用的文件不是LUT,则将其忽略。从最快到最精确列出了以下插值方法:

nearest

linear

working space

working_space

scene_linear (linear)

设置应用文件的色彩空间。输入从场景线性转换为指定的working space,将应用文件颜色转换,然后将结果转换回线性场景。

mask

在右侧启用关联的遮罩通道。禁用此复选框与将频道设置为none.

maskChannelInput

none

The channel to use as a mask. By default, the colorspace conversion is limited to the non-black areas of this channel.

inject

inject

disabled

复制mask输入到预定义mask.a渠道。注入面罩可让您在下游使用同一面罩。

invert

invert_mask

disabled

反转蒙版通道的使用,以便将颜色空间转换限制为蒙版的非白色区域。

fringe

fringe

disabled

启用后,仅将效果应用于蒙版的边缘。

禁用时,该效果将应用到整个蒙版。

(un)premult by

N/A

disabled

在右侧启用关联的通道。禁用此复选框与将频道设置为none

unpremult

none

The image is divided by this channel before being processed, and multiplied again afterwards.

If you are using premultiplied input images, you may want to check (un)premult by and select rgba.alpha here. This will simulate doing the color conversion before the premultiplication was done. It is the same as adding an Unpremult node before this node and a Premult node after, but allows you to work faster if you’re only using one color correct node.

If you are using unpremultiplied input images, you should leave this set to none.

invert

invert_unpremult

disabled

反转(非)预乘通道的使用。
