A feature film has been cutting here at Trim over the past few months, so I took the opportunity to hijack the project to see what the export speeds were like. A ProRes HD file took 2 minutes 34 seconds, which is pretty great for a 90-minute timeline. But compressed H.264s are far more common for me as an editor when dealing with upload and review of my cuts. My biggest frustration with all previous Mac Pro machines was that their H.264 export speeds always seemed terrible. This is due to the fact that "workstation-class chips" don't have the hardware-acceleration necessary for these tasks. So I was pleasantly surprised to find that Apple seem to be bypassing these limitations somehow, and the iMac Pro is also delivering fast H.264 exports. I have no idea what they are doing behind the scenes to achieve this, but it works and will save me hours in encoding time.
Next I decided to push the resolution right up and see how it might handle a ludicrous 8K timeline with footage shot on the Panavision Millennium DXL. With 8K ProRes 4:4:4:4 files, the iMac Pro played the sequence back perfectly. Even after adding a couple of color corrections and a blur to the clips it still didn't drop a frame. I should add that this was playing back at better quality and without rendering. I'll repeat that once more. 8K. Color correction. Blur. No Rendering. No "1/4 quality" BS. No frames dropped.Yes, 8K is an impressive number, but I was also interested to see how it might handle a less friendly codec like R3D, a notoriously heavy codec for computers to decode/debayer and playback at full quality. The maximum I managed to test here was 5K Red RAW footage in a 5K timeline. Again, best quality and unrendered. Adding color correction, resizes and titles didn't cause the machine to drop frames. The sequence played through smoothly, which is nuts.
While this last test is really impressive, there aren't many real-world jobs where I'll be storing an entire film shoot of Red RAW rushes on my internal SSD. So I also checked how this played out on external storage. I'm happy to report that loading the same media onto our Jellyfish shared storage and accessing it over direct-attached 10Gb Ethernet gave me the same results.These tests really blew me away. They aren't necessarily going to be everyday scenarios for most people, or even me, but they make it possible to imagine editing workflows in which you're working at close to the highest quality possible throughout the entire process on a desktop computer. A space grey one. It's going to be really interesting to see how the rest of the company reacts to this computer moving forward. While we mainly deal in offline workflows, we have begun to look at possibly taking on more conforming, online, grading work in-house. It's not hard to conceive that the iMac Pro could be the tool to bring all these elements together for us in a streamlined way.
The Bottom LineWhile I really haven't had enough time to do a deep dive, it's clearly the best Mac I've ever used - it's stupidly powerful and great to work on.But who is it actually for? Clearly not everyone. It's quite obviously a pro machine and it comes with a price tag to fit - $4,999. If you're a pro user who needs a Pro Mac, it's probably for you (and you can get your hands on one starting December 14). If you're already an iMac user but you need more power, it's probably for you too. If I had to make a wildly uninformed guess, I'd say this will be more than enough computer for 90% of pros.

Ga zelf eens lekker een computer in elkaar zetten, gaan we jou in de zeik nemen Net zo makkelijk!
