Resolve Mac – Resolve Linux same hardware

[Peter Chamberlain]

The GPU in both the Mac and Linux versions does all the PTZR calculations (Transformer in old systems) as well as the color grading work. If you have 2K source files and a HD deliverable there will be a resize for every shot. This uses some of the GPU power, but will still allow a lot of grading layers in realtime. For projects with HD source and final output you can still obviously resize or rotate the image for artistic benefit but otherwise the GPU would just be for grading.

While the GTX285 for Mac is a powerful GPU and offers quite a few HD layers, the 4GPU Linux systems offer 20+ nodes of 2K in realtime. Render speed is mostly limited by disk performance and file system and not by color correction processing, thus Resolve is able to render faster than real time even at 2K in the Linux system.

As an aside – Resolve is 64 bit and uses either Linux or Snow Leopard both with multi-threading. More/faster CPU’s in the system help in the none grading/PTZR part of the application.

Pre BMD Resolve systems are generally similar in speed or slower than the new Mac systems. As a reminder for existing Resolve facilities, we offer an extremely attractive software upgrade program, just call your DaVinci Resolve distributor.

The qualified GPU for Linux Resolve is the S4

The hardware systems are a completely different beast from the Mac based systems, yes the software is about the same, but your performance will be rather different when you look at the two sets of qualified specs 🙂

Does it require SnowLEPER or is it just an advantage (if you don’t have to count on the system stability too much)? I’m assuming Tiger is a non-starter, and at least Leopard, but no 64-bit with that one. Forgive me, but my experience is that Snow Leopard is at least as bad as Windows Vista as an operating system, and Windows7 is not much better than Vista.

*in the none grading/PTZR part* — I’m thinking that was a typo and you mean “non-grading”… like the UI and scratch composites, still store, grade management, EDL processing, … etc?

Thanks, yes a typo, that’s non-grading items.. there are plenty, not the least is real time RED r3d de-compress and de-bayer which is CPU intensive; And Yes, requires Snow Leopard.. we have not experienced the difficulties you mention in our test systems.

Any hope the Linux verison will be able to write ProRes in the near future? I’d assume Apple would be more open to a Linux port of the ProRes codec than Windows.

There\’s very little hope that the ProRes codecs will be ported to the Mac.
Until then, the best course for a Linux Resolve is to…
1. Export from Linux Resolve to an uncompressed QT and convert that to ProRes in a Mac.
2. Open the Linux Resolve project in a Mac Resolve, and render from that as ProRes.

We routinely do #1 and it works just fine.
