I'm posting this to both the blender development list and the blender
vfx list as I think it is relevant to both.
This package is meant to illustrate the current deficencies in Blender
with regards to 1) DPX handling , 2) color management and 3)
ASC-CDL compliance .
I am a freelance cinematographer with a hobby interest in both open
source software and post-production. I have had experience working
with a colorist on already mature color grading solutions for Linux
like Baselight and Davinci Resolve. I would love to see Blender's
power and flexibility as a 3D modeling and compositing solution be
extended to that of a colorist.
Even before that though, Blender needs to get it's ImageIO and color
management house in order.
With in this package you will find as follows:
* Example .blend files.
* Screenshots of the tested setup.
* Reference DPX's and the .ccc list from the ASC-CDL reference
distribution included for convenience
* Blender's output from the .blend files rendered as DPX
For reference I have used the iv utility from the OpenImageIO project
and their DPX implimentation as being correct and complete.
OpenImageIO can be obtained from https://sites.google.com/site/openimageio/
OpenImageIO was compiled from a recent trunk.
If I have made any errors or omissions, please let me know. I've did
this testing with the intent of sparking discussion.
