ID 520941 - Nuke always reads ProRes files in Video Range and this cannot be changed with the Data Range knob

Problem summary

Nuke always reads ProRes files in Video Range and this cannot be changed with the Data Range knob.

The Data Range knob only appears to work for DNxHD files. 

Customer reported version

Nuke 13.2v4

Customer reported platform

CentOS 7

Steps to reproduce

1) To reproduce this issue, you will need a ProRes file that was encoded in Full Range.

Two example files are attached, one which was rendered in Full Range and the other in Video Range.

2) Open Nuke.

3) Read in the attached ProRes files.

4) Notice that the Full Range ProRes will look more contrasty.

Additionally, you can compare the results to third party software which allows you to change the Data Range for ProRes files (such as Resolve).

Expected behaviour

The user should be able set whether ProRes files are read in as Full Range or Video Range.

Actual behaviour

Nuke always reads ProRes files in Video Range and this cannot be changed with the Data Range knob.

Workaround

Unknown.
