ID 409739 - QuickTime files rendered as mov32 do not export nclc data correctly within later Nuke 11.3 releases

Follow

Problem summary
QuickTime files rendered as mov32 do not export nclc data correctly within later Nuke 11.3 releases.

While there is no visual difference within Nuke, this causes issues with external programs that read this metadata and use to apply color variations.(e.g. RV)

This issue only occurs in Nuke 11.3v5 and later versions.

Customer reported version
nuke.12.0v1

Customer reported platform
windows10

Steps to reproduce

1) Open attached script in Nuke 11.3v4 (or earlier version) and render

2) Re-open attached script in Nuke 11.3v5 (or later version) and render

3) Open rendered QuickTime's and compare the results in the Viewer
Result: No difference

4) Compare the metadata using a CompareMetadataNode
Result: Nuke 11.3v5 does not have the same 'nclc_matrix' and 'nclc_primaries' data.

5) Open the rendered QuickTime's in RV and compare
Result: The difference can be seen visually with Nuke 11.3v5 version darker.

Expected behaviour
QuickTime files that are mov32 should retain the correct nclc data for use in external programs

Actual behaviour
QuickTime files that are mov32 do not retain the correct nclc data for use in external programs

Workaround
Unknown.
