Possible quickies:   Meta-Data / Format to better pass setups involving OpenFX Plugins, I think Gary was part of discussion with OTIO about effects....
Meta-Data, Spatial and Temporal (some is parameter related) -  Pierre holding as Color was voted as to address before.

Follow-up to short - discussion at started Dec 6 Meeting







OCIO


Issue #102

PR #103

BorisFX JP Smith to describe their OFX-OCIO mapping, intiially developed so Silhouette and Mocha look at same color. Objective is to have something.  Comments from Assimilate and Filmlight who don't internally work with OCIO model, how is this used by plug-ins and host to communicate?






comment by Pierre:  There is ASC CDL which somehow requires to be encapsulated into a color space to make sense. There is also new ACES look-up tables and old ones. There is also simple needs such as knowing if input is linear or not without changing the output colorspace...Dennis Adams mention OSL also has questions about colorspace (it's also right now being somehow merged with MaterialX which also has similar issues), and I have a problem with all the new GPU API that collapse pixel color format and color. Also space (e.g. linear sRGB… - do we want piecewise format?). Finally pixel format (e.g. RGBA etc) - I think it makes the API simple but opened to suggestions, I have seen mess in some other API trying to define a lot of color format YUV 422 etc bla bla... However there is something about 10bit/12bit source with defined black and white point we might want to consider for 16bit short buffers? Finally because we (RE:Vision do things like color stabilization we could use if available AWB and AE data etc - this might fall in Meta-Data though not here. Also OCIO and ACES don't have the same white point (D60/D65 chromacities)

no action needed other than collect data points
