Phoronix: OpenColorIO 2.3 Released With New AVX/AVX2 Optimizations

OpenColorIO (OCIO) as the open-source color management solution for motion picture production and maintained by the Academy Software Foundation is out with a new feature release that will be part of their 2024 VFX Reference Platform. Notable with this release are new SIMD optimizations with AVX/AVX2 and Arm NEON...

"This open-source color management solution has been used by films like SpiderMan 2, Alice in Wonderland, Surf's Up, and many other films"

This list is quite funny and completely ridiculous because it is actually used on 100 percent of any movie made nowadays.

So much? Really? I'm interested on knowing more about it. Please elaborate!

The key softwares used in the vfx industry (nuke, houdini, katana, maya/arnold etc, even unreal supports it) are all relying on OCIO for their color management.
So, there is literally not a single project in 2023 that is not using OCIO at any point.

ACES the film post production colorspace standard, itself is implemented as an OCIO config too.

So yes, OCIO is everywhere.

Time for shilling since this is still loosely on topic, if anyone is interested in a free and open source NLE, that while is still very infantile, has great foundation, Olive video editor is looking for somewhat serious investors as the main and only dev working on it no longer can afford to. It has a node based effects editor, works in linear and all color management is handled by OCIO. It supports custom OCIO configs (for anyone who wants to use a full aces one) but default comes with a modest but nice config for working with srgb/rec.709. this also means you have accsess to the color transforms via ocio configs, olive has a couple baked in.

For me it crashes less then kdenlive, it will hopefully eventually support custom GLSL filters (there is a PR up for it now), and at least for me, I can edit 4k30 AVC footage without the need for caching or a proxy file (though a proxy file is better) and without the need for serious downscaling in the preview editor something that only olive has been able to accomplish for me

Keep in mind this is still very alpha software by a dev working on it in his part time, but as stated, it has the foundation to be a proper professional piece of software with things like color grading and advanced effects pipelines already having solid ground. I personally use this in my capacity despite it being fairly limited since I don't really need a lot. you can read more about it with the links below.

Would this be used outside professional video/image like desktop?

a compositor might use it when it comes to color management whenever the wayland colormanagement stuff lands, I doubt it, but it is a possibility

It seems a quite developed codebase. Why not?

it's pretty heavy, but actually aside from that I think it could work well
