qp Nuclear LUT适用于在After Effects中转换Log-线性函数来显示正确的画面颜色编码，同时保留其亮度数值。

就像你在应用一些LUTs一样。

说明

出于明显的原因qp Nuclear LUT效果最好在32-bpc，并且仅当AE被设置为线性工作空间。

你也应该在解释素材设定时保留RGB，所以工作空间的色彩变换（如sRGB或HDTV Rec.709）不应该首先应用。

目前只有S-LOG2-线性一种方式。

更多其他的功能将在以后的版本中加入，如PLogLin 以及 S-Log1 & 3。

qp Nuclear LUT applies log-to-lin functions to show log colour encoded footage properly in After Effects, whilst retaining its over bright values, just like Nuke does with its read/write nodes.

Instructions

For obvious reasons qp Nuclear LUT works best at 32-bpc, and ONLY when After Effects is set to a linear working space.

You should also turn on Preserve RGB in the Interpret Footage settings, so the working space colour transform (e.

g.

sRGB or HDTV Rec.

709) isn’t applied first.

Simply choose the colour space from the drop down and which direction you want the function to go:

To Linear (In) is used to simulate Nuke’s read node and converts from the log encoding to AE’s linear space

From Linear (Out) is used when you want to write back to log at the end of your compositing chain

As most of the log functions tend to negative values below the black point, you can choose to clamp these values to zero.

This is only recommended if you’re not outputting back to the log space, i.

e.

if you’re grading a log-encoded shot and want to output to, say Rec.

709.

Important Notice

At present the S-log2 function is one way only (log to lin).

The reverse function will be added in a future version, along with PLogLin and S-Log1 & 3.
