Have you ever used Resolve? I have been using it for years, getting it to work reliably on Linux is a nightmare, there's all sorts of text and GUI scaling issues, and that's assuming you can even get it to launch and run after you have it installed. The most success i have had is with Ubuntu and Fedora, the rest of the distros I don't even bother.
If you want the best Resolve experience you use a Mac, and specifically the new M1, with a Windows based pc being a close second.
Hate to break this to all those living in Linux fantasy land, but if you want reliable, quality video editing of any kind, you nearly always want to first go with a Mac and then a Windows based system as a close second.

Originally posted by mroche View PostTo add clarification, "studios" tends to refer to feature animation studios e.g. Pixar, WDAS, DreamWorks and contracted VFX studios e.g. DNeg, DD, ILM, MPC, etc, usually on the medium to larger size. In this situation, the use of RHEL/CentOS is pretty much de facto, and not just for servers. A good portion of that stems from the transition from IRIX (MIPS) to x86 where Red Hat Linux was ready to scoop up that customer base. I personally worked at Pixar and Blue Sky (at Red Hat now, thanks Disney), along with knowing what a bunch of the other studios are doing because we all talk with each other and our vendors.
But since you arbitrarily defined "studios" in the manner you did and since you mentioned Pixar, let's see what a Pixar scientist has to say:
Pixar has a huge "render farm," which is basically a supercomputer composed of 2000 machines, and 24,000 cores. This makes it one of the 25 largest supercomputers in the world. That said, with all that computing power, it still took two years to render Monster's University.

As for Dreamworks:
One of our first realizations, after meeting an animator, is that just about every frame of a movie such as Rise of the Guardians is created using an HP Workstation Z820. This behemoth is outfitted with two Intel Xeon E5-2687W processors, running at 3.1GHz each. Because each system has eight cores, animators can use 16 cores for processing animation files.
Now this article is a bit old and the HP workstation referenced is available with either Windows or Linux, so maybe they do use Linux in some rendering capacity, but according to this they use Premo, which seems to be a custom built software:
With franchises like Shrek, Kung Fu Panda, and Madagascar to its name, DreamWorks Animation has spent the last 20 years building an animation mini-empire. The studio’s movies have pulled in over...
Studio R&D director Paul Carmen DiLorenzo walks us through the studio’s groundbreaking and innovative production system being recognized at this Saturday’s MPAA Scientific and Technical Awards.
Honestly, the more I read about the custom software that Pixar and Dreamworks use, the more I think that they may not even run on an OS per se, they may be using custom setups where the rendering software runs on bare metal, maybe even coded with extensive assembler, based on the claims of speed.

That is because HDR is classified by both contrast and colour depth, so the 8-bit HDR displays have the extra contrast but not the extra colour depth and since they support HDR contrast they are "HDR", just that they don't have to specify which of the classifications they met.

Studios don't use Linux when they need to do color because Linux is absolutely terrible in this.

Since then, I've noticed plenty of banding with 8-bits per channel. Right now, I can see it in the part of the yellow sky of my desktop wallpaper -- a massive panorama, taken from the mars rover, displayed on a true 8-bit (SDR) LCD. I know those artifacts aren't baked into the image, since I took the full-resolution image from NASA and cropped/scaled it myself. Moreover, I even used a color picker to confirm that they're actually just single intensity value differences.

Examples for you to ponder (as these are studios I had direct relations with):
*Pixar:
- Render farm nodes run RHEL
- Workstations are vSphere VDI over Teradici PCoIP running RHEL (using MATE, some of us in systems used GNOME).
* WDAS (same as above, not sure if using vSphere or something else and which DE they settled on).
* Blue Sky
- Render farm on CentOS
- Desk-side workstations running CentOS (using Cinnamon, formerly XFCE).
Every studio I've mentioned so far in my prior comment, that others have mentioned, and more also use Linux as their primary pipeline desktop OS.
Thank you for making my night with this. Have a great weekend.
Cheers,

This comment is rather puzzling, as if you're expecting that each advancement in technology should be immediately relevant to the majority of users. Traditionally, the boundaries of tech are pushed by the most demanding users. Then, as the tech matures, it trickles down to the mainstream, where other opportunistic applications take advantage of it and widen the pool of beneficiaries.
In this case, the early adopters should be:- Video production
- Video consumption
- Photo editing
- Games

Also, talk of render farms is missing the point, since the matter in contention seems to be that of desktop Linux.
Originally posted by sophisticles View PostHonestly, the more I read about the custom software that Pixar and Dreamworks use, the more I think that they may not even run on an OS per se, they may be using custom setups where the rendering software runs on bare metal,
At most, they'd likely just use customized kernel parameters & build options.
Of course, I'm just speculating, but then so are you. At least I've seen the inside of some professional 3D and video post production software. I'm sure the developers have enough to worry about, without trying to do the OS' job too!
