[Bf-vfx] MovieClip Data Elephant in Room

[Xavier Thomas]

Yes, I investigated a little the subject and it seems lcms2 ans
OpenColorIO are the only solutions that can fullfill the need of
Blender (other libs such as lcms1 have issues with 32bit float
images).

While both can do the job, OpenColorIO is verry much oriented CG and
VFX while lcms2 is more oriented for printing, so OCIO seems like a
better match (mainly because of, realtime GPU processing, the
supported LUT file formats and default profiles).

I wish I had more time to start coding on this but I can barely finish
the work I started on gamekit/animkit. Hopefully this will change in
the future.

Also, to me, integrating OpenColorIO to have full control over the
colormanagement in Blender; does not seems like a complex or
technically difficult task. But it is something that would be time
consuming and require a lot of tests.

Last, but not least, Jeroen Bakker seems to have started OpenColorIO
integration work in his OpwnCL compositing branch.
