AkiTio Node

In the quest for quicker will be an unofficial but recurring series on this blog going forward. I was born with a deficiency…a lack of patience. Processing, backing up, renaming, all tasks that operate on an automated basis and are limited by the one’s and zero’s your setup can crunch… Time is money, and I value time more than money.


The most recent foray into improving the usability and time:money ratio of my system was to try an external GPU. Thunderbolt 3 has finally removed the bottleneck of being able to shove the polygon crunching power of an external GPU down the pipe and into the motherboard/logic board and so coupling a cheap enough AkiTio Node and as expensive as you’d like to spend GPU, you can improve your image processing times by quite a significant degree. Rhetoric? Waxing poetic? Here’s the numbers;



Proof in the pudding

Common tasks for a Photography DIT is processing baked looks into 16 Bit TIFF’s for the client/post house. We processed 200 5DSr photographs and compare the time difference from the first and last image. We did this on the available setups we have starting with using the laptop and its built in GPU’s. Below is a rundown of the setups used.

Laptop – MacBook Pro 15″ Late 20162.9Ghz Intel Core i7 / 16GB 2133Mhz LPDDR3 / Radeon Pro 460 4096MB & Intel HD Graphics 530 1536MB
Laptop & AkiTioSame as above, including an eVGA 1080Ti FTW3 in an AkiTio Node enclosure running through Thunderbolt 3
RackintoshCustom built rack mounted OS X build. 4.6Ghz Intel Core i7 / 32Gb 2666Mhz DDR4 / Zotak 980Ti Amp Extreme & eVGA 1080Ti FTW3 / nVME 2GB/s SSD

There is a strong lead with the rackintosh, but it is far from mobile and requires a more studio based setting. It is often overkill for many jobs. The laptop & external GPU performs very nicely in comparison to the laptop solo. Final processed tiff’s can often be in the thousands so this is a short window into the potential time saved. If you think this is the route for you, read on and see how easy it is to get going.


How do we get there?

First, buy the hardware you need. It’s a two item ordeal. The AkiTio Node & GPU of your choice (Keep to nVidia if you’d like to make your life very simple).

Install, cable up with the sadly extremely short TB3 cable, and run the following commands in the Terminal;

curl -o ~/Desktop/metaltest.swift https://raw.githubusercontent.com/goalque/automate-eGPU/master/metaltest.swift

cd ~/Desktop

swiftc -sdk $(xcrun --show-sdk-path) -target x86_64-apple-macosx10.11 -o metaltest metaltest.swift

Note: SIP Needs to be disabled. If you do not know how to do that, the AkiTio Node might not be for you.

Reboot, and hey presto — you’re in. You can hot plug your monitors no problem. At least, we could — your mileage may vary!



The question is, is it worth it? The AkiTio Node comes in around $300, the best GPU you can buy right now besides Titan money is the 1080Ti at $800. This performance increase is definitely significant enough that there isn’t a need to upgrade the CPU or RAM on a laptop to squeeze out the last remaining life out of it. An external GPU is breathing life into these machines the same way SSD’s did 5 years ago.

In fact, if you’re creating dailies and aren’t dealing with more than a single-pass h.264 deliverable, the laptop & eGPU will actually far outperform any current Mac Pro offerings and would even surpass the 5K iMac. Interesting food for thought. Read on if you’re curious why.



Now playing around with the AkiTio has had us delving pretty deeply into the inner workings of performance benchmarking and it brought us to an interesting head-scratch with regards to a benchmark we were performing in DaVinci Resolve. The benchmarks above show just how much more powerful the Rackintosh is in comparison to the laptop. The laptop is no slouch, either. It’s the most expensive current MacBook Pro offering, and even rocks an SSD fast enough that writing to the disk wasn’t a bottleneck either. The curious problem was that the laptop was far outperforming the Rackintosh on a h.264 compression benchmark. Why?

The answer is a little CPU embedded hardware based encoding/decoding utility called Intel Quick Sync. That’s right. A feature that is standard on a lot of consumer chip offerings by Intel will improve your (single-pass only) h.264 encoding times by double, if not more. So your Core i5 might even make a Mac Pro eat shit due to the Mac Pro running professional grade Xeon chips that are inherently much more expensive, and also lacking… Intel Quick Sync. So if you wonder why so many Video Content Creator’s love the iMac 5k, it’s because it actually IS faster for their application than a Mac Pro.

I’ll be following up about Intel Quick Sync and benchmarking the latest Apple offerings further down the line. It’s an interesting gotcha that many overlook.

Quick Tip: Set Capture Folder & Reset Capture Counter

With the release of Capture One 9.1 comes a fantastic new addition in the shortcuts menu. Reset Capture Counter. With the ability to assign a workflow or a sequence of custom events using software such as Keyboard Maestro, we can make one shortcut change our shot folder and reset our capture counter all at once.

The benefit of this set up, and having shot-lists written out ahead of time, is that you can assign your naming format to follow the name of the shot folder. This means that so long as you’re accurately keeping tabs on what’s being shot, your file naming will match live without the necessity of a post-rename. This saves valuable time as you can then start your batch processing whilst additional shots are being shot. Another tip is to take advantage of tokens in your batch processing folders, too. I’ll write more about this in another tip.

Software Needed
Capture One 9.1+
Keyboard Maestro

In Capture One you’ll want to find the shortcut for ‘Set Capture Folder’ and ‘Counters’. They’re both going to be set to the following for the sake of this tutorial.

Keyboard Shortcuts > File > Set as Capture Folder > CMD + F

Keyboard Shortcuts > Edit > Counters > Reset Capture Counter > CMD + Shift + 2

Now over in Keyboard Maestro we want to put both of these shortcuts together into a single shortcut. We’ll place a slight delay in there just in case it takes Capture One a moment to switch folders over. Copy these settings below.


Now any time you select your capture folder in Capture One and press CMD + Shift + D You’ll change the capture folder to the one highlighted and you’ll reset the capture counter to zero.

I have this macro set to display a notification once it has been executed. This lets me know that I didn’t miss-type and if I do not have the capture name window currently active, it’s a secure reminder that it did the job. If you’d prefer not to have a notification displayed, you can simply not add it to your macro.

I’ve included a download to this macro so you can simply edit it to match your system settings.

Disable Auto-Opening of Photos

Plugging in an SD Card and Photos keeps popping up? You know the trick to stop it from opening up but plugging in a new SD Card or a formatted one and it still won’t stop bugging you?

Head to terminal and enter:

defaults -currentHost write com.apple.ImageCapture disableHotPlug -bool YES

Enjoy your peace and quiet!
