ASFW. The Academy Software Foundation, which is a project from the Linux Foundation, which help create, support, and fund, FOSS software used in the cinematography industry, and backed by tons of pillars in the industry, such as Walt Disney, DreamWorks, Weta Digital, Warner Brothers and the like. Discovered it recently with a blog post of Kdenlive which has recently been added, and include software like Blender, Olive, Natron, GIMP & ImageMagick, but also, software frameworks like OpenColorIO, OSL, OpenTimelineIO, BulletPhysics, OpenCV and the likes.
And yes, It includes also, support from companies which ironically, are pretty much against Linux desktop expansion, such as Adobe and AutoDesk but meh. Atleast, they support the project financially.
