qp Nuclear LUT適用于在After Effects中轉(zhuǎn)換Log-線性函數(shù)來顯示正確的畫面顏色編碼，同時保留其亮度數(shù)值。
就像你在應(yīng)用一些LUTs一樣。
說明
出于明顯的原因qp Nuclear LUT效果最好在32-bpc，并且僅當(dāng)AE被設(shè)置為線性工作空間。你也應(yīng)該在解釋素材設(shè)定時保留RGB，所以工作空間的色彩變換（如sRGB或HDTV Rec.709）不應(yīng)該首先應(yīng)用。
目前只有S-LOG2-線性一種方式。更多其他的功能將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.
