Extract ASC CDL grades from an AvidLogExchange (ALE) file format and write out to an ASC ColorCorrectionCollection (CCC)
My 5 minutes of searching online for a script to do this already proved fruitless. So I threw this together. Its not pretty, but it gets the job done.
The output .ccc has been tested to with the OCIOCDLTransform node in Nuke 6.3v8.
%prog infile1.ale infile2.ale ... infileN.ale outfile.ccc-
The variable NAMING_CONVENTION_REGEX contains the regex used to create an id attribute for each of the ColorCorrections contained in the collection.
-
If the ALE file does not contain Columns named ASC_SOP and ASC_SAT the extract will fail.
-
Files which do not match the regex are warned and skipped over.
Example Color Correction Collection file:
<ColorCorrectionCollection xmlns="urn:ASC:CDL:v1.2">
<ColorCorrection id="af-123">
<SOPNode>
<Slope>2 1 1</Slope>
<Offset>0 0 0</Offset>
<Power>1 1 1</Power>
</SOPNode>
<SATNode>
<Saturation>1</Saturation>
</SATNode>
</ColorCorrection>
<ColorCorrection id="mygrade">
<SOPNode>
<Slope>0.9 0.7 0.9</Slope>
<Offset>0 0 0</Offset>
<Power>1 1 1</Power>
</SOPNode>
<SATNode>
<Saturation>1</Saturation>
</SATNode>
</ColorCorrection>
</ColorCorrectionCollection>
