I'm a bit puzzled about this portion.
I assume rendering farms in your industry are similar to other industries. Render farms consist of computers sitting in a server room away from work desks. The computers could be discrete workstations or rack mounted machines. In such case, what would be the advantage of moving from PC to Mac?
And then in terms of migration timing. These studios should know (and perhaps know much better than the general public) about Apple's plan on AS Mac Pro. Knowing Apple is going to discontinue Mac Pro 2019, what have encouraged these studio to migrate to Mac Pro 2019 in 2021/22? Rather than not holding on to PC workstations (with intermittent PC hardware upgrade if needed) a little longer. And do the migration to Mac when AS Mac Pros are released? I meant Mac Pro 2019 is great, and a great PC too. That means non-user interactive machines could be served by PCs not made by Apple.
Lastly, what's so special about Puget Systems to these studios? I meant PugetSystems must have done something great to receive contracts from these big guys. But PugetSystems aren't without competitors in workstations. HP, Lenovo and Dell all three have some fantastic and well designed workstations, powerful rack mount computers. I would think they would fight hard to win big studios to be their customers.
I'll speak frankly...there are THREE main focuses in production...everything falls underneath one of these focuses...PRE production, PRO duction, and POST production...preproduction is 100% writing, storyboarding, previzing, color boarding, planning, location scouting, and more...all of which are best done on systems that can PLUG AND PLAY with everything else around them and without any setup and immediately...as a result, pre-production is DOMINATED by Apple products. Between Mac Pros, iMacs, MacBook Pros, iPads, and even iPhones, ALL of the assets can be accessed, added to, edited, and noted from EVERY SINGLE ONE OF THOSE DEVICES, and when new team members pop in, they are literally plug and play into the ecosystem...I have even received location scouting storyboards on my Apple Watch in traffic and approved them...nobody wants to nor has any kind of desire to leave behind such a rock solid system.
Then there's PRODUCTION. Production is dominated by APPLE AGAIN...because that same plug and play system that worked in pre-production, works on set. THE OUTLIER HERE being virtual sets which are DOMINATED by Puget Systems. Primarily because as I mentioned in a previous post, Unreal Engine 5 runs extremely well on Macs, but is NOT at parity in functionality with what it can do on PC. And considering EPIC and APPLE have been at war for some time, who knows when that will change. So for studios running primarily virtual sets, they will be dominated by PC. Beyond that, every set you walk onto AND IN THE FIELD AND ON LOCATION, it will be 100% Apple. There are always two or more on location editors and colorists on their MacBook Pros doing rough cuts, basic color ideas on dailies, and more on location and all of that is being airdropped, exported, and broadcasted to every monitor on location and throughout the studio.
Then there's POST PRODUCTION. Now this one is split in HALF. Because there are funnily, 3 main pillars of post production as well; The Edit, The Color, and The VFX. The edit rooms and edit bays are dominated by Mac Pros and iMacs, the Coloring Bays are a toss up, because industry standard for color, Black Magic's DaVinci RESOLVE runs equally well on both systems, and usually based on the setup of the color room and the rest of the pipeline will dictate which system is running the Resolve. The Avid is usually industry standard for feature films above $20 million on budgets, below $20 million I tend to see a toss up between Premiere and FCPX, and then for music videos, commercials, trailers, etc...FCPX seems to be the way most indie studios go. But the HUGE OUTLIER is in the VFX Department. If your project relies on basic general VFX, object removals, sign replacements/additions, adding pre-keyed elements, set extensions, screen replacements, etc...it's usually Mac based...if however, its 3D ANIMATION and HEAVY 3D OBJECT, CITY, DESTRUCTION FOCUSED VFX, then it's going to be PC, because the decades long war between Apple and Nvidia, which literally is the flick of a switch to fix...Apple won't sign drivers for Nvidia GPUs...and conversely for anti-compete reasons only allow METAL to be the driver for 3D work...PC DOMINATES this portion of the post production field, and so virtually 99% of all houses doing heavy 3D work will be PC based...this means that around 75% of all work in Hollywood is done on Mac and roughly 25% is done on PC.
As for render farms, you are correct, 90% of them are PC based and everyone exports to them, but you'd be shocked how little that impacts the systems preferred by the artists and weirdly, the pencil pushing side of things...
And to speak to Puget, they just jumped in very quickly with their custom systems for virtual production and I think honestly, they played the game extremely aggressively because they are genuinely dominating these days from what I've seen when I go work on outside productions "I own my production company, but I also am an artist myself and have served as VFX Supervisor on around a dozen feature films, and dozens and dozens of commercials, trailers, behind the scenes projects, special projects for Disney+ extra content, sports packages, etc..." and I'm an actor as well, so I also see what's going on when we are live on set shooting in both the studio sets and out in the field as well on location.
So I see this industry all day everyday from all angles of it both in front of and behind the lens, both above and below the line, and these are just my observations I am sharing. Of course, your observations may be different which is why conversation and discourse is so valuable and helps our community in general to grow and make healthy, and educated purchases
