I too can play the 12K into a HD timeline, and if I watch what I do, I can play 12K into an 8K timeline all day long. My problem is 12K raw in resolve. Dwaine was very helpful with his explanation. I'm just working the edges to see where the sweet spot is for the different resolutions. So far, 12K needs more VRAM. If I load a small 12KCQ video (around 300 frames worth) I can deliver it with an issue.
When I start to grade and add filters and such, and things start to fall apart. But if I save the project. Close Resolve. Start Resolve, and then deliver with everything in place: there is no issue delivering at 12K. It's just such a chore to run this workflow.
I'm going to add as much VRAM as I can. Today it's 24GB on the 3090. Tomorrow it will be an A6000 with 48GB. It would be easier if Blackmagic could map all the VRAM into a single system and then work on it as a single contiguous memory space. Maybe Blackmagic could use NVLink.
NVLink enables professional applications to easily scale memory and performance with multi-GPU configurations
And I assure you I wouldn't flame you. I looked at the Mac Studio. But at $6k for a single use platform just couldn't justify the acquisition. The A6000 costs $5K, so I would have actually saved a grand and had better expandability in the future. And everything I have today will continue to work in the future without having to spend 10s of thousands of dollars.
Now if we can only get BM to create a render farm, we'd all be able to render massive 12K projects in minutes. What about it BM? I analyzed the render farm Pixar had in the 2000s. Our goal was to move them off their current platform and onto something more flexible. They had lots of small compute engines all tied into a single render behemoth.
