macOS | DaVinci Resolve | eGPU

An eGPU or two may not provide the extreme increase in rendering power that you might expect, at least not while using DaVinci Resolve.

8-bit color banding

No matter how much bitrate is thrown at this cropped 4K footage, there is no way of getting around banding while staying in an 8-bit space. The same render in 10-bit shows no sign of banding at all, even when compressed down to 10Mb/s HEVC 2160p24. Is this banding apparent while watching on a 6.5” iPhone XS Max screen? no not really. But on a 65” OLED in HDR sitting 8’ away the banding is easily apparent.

560X | WX9100 | Enhanced Noise Reduction

Here’s a good reason to use the WX9100 as an eGPU:

While using the new Enhanced Spatial Noise Reduction of Davinci Resolve to render a 1.5 minute 4K RAW clip, the AMD 560X takes a whopping 1 hour and 4 minutes. The same clip took only 12 minutes and 33 seconds with the WX9100 connected. Hell yeah.

RED Raven R3D 22:1 Render Time

R3D Redcode Raw 22:1

Render to: HEVC 8-bit (10-bit still crashes)

Decode Quality: Full Res. Premium

Timeline length: 4m50s

AMD 560X: 9m50s

AMD 560X + WX9100: 5m19s

Only 1 power window in a separate node added to black out a label. No color wheel color correction added to main video, only RAW adjustments. The WX9100 provides close to realtime encoding. RED’s RAW noise reduction does not take a penalty on render times; i.e. no denoise and maximum denoise were only different by 2 seconds.

Bonus info: Since I’ll be renting the RED Raven for the first time tomorrow I thought I’d compare Blackmagic’s sensor sizes to RED’s lowest end sensor. The RED Raven does have the same Dragon sensor as it’s older siblings, but dimensions are smaller, leading to a lower resolution and cutoff footprint. RED pretty much shaved the sides of the Dragon sensor, lowered the price and called it a day. Works for me, as I certainly cannot afford an Epic Dragon at this point.

AJA System Test Lite

macOS Mojave Beta 18A365a

MacBook Pro 15-inch 2018

Intel Core-i9 8950HK 2.9GHz 6-Core

32GB DDR4 2.4GHz

AMD Radeon Pro 560X 4GB

Intel UHD Graphics 630 1.5GB

AJA System Test Lite is a benchmarking app that tests READ/WRITE speed of a storage device as well as its respective maximum capable playback/record frame rate in various video codecs.

AJA.png

The frame rate results represent AJA RAW 12bit DNG, which also being a DNG is most likely close to CinemaDNG RAW. The URSA MINI 4K shoots between 24-60fps 4K to SATA III based CFast 2.0 Cards which cap at a theoretical maximum bitrate of 750MB/s, nearly 1/4 the speed of the MacBook Pro PCIe 3.0 SSD.

In order to realize 4K RAW frame rates like these, either a faster interconnect such as the proposed CFexpress is needed, or RAW compression like what Blackmagic and RED use which lowers bitrate while retaining visual quality. CFexpress uses two PCIe 3.0 lanes to provide a 2GB/s bandwidth.

Navigating the Terminal

Terminal.app

The ~ character is known as a Tilde (pronounced like milled but with a T). ~ is used as short hand for your home directory.

~/ is therefor the same as navigating to your home folder in the finder or pressing Cmd + Shift + H.

Since your desktop is located in the home folder, the path is ~/Desktop
using the cd command we can navigate to the desktop using Terminal.
write or copy and paste cd ~/Desktop into the Terminal and hit return. Entered correctly, you will be prompted with user:Desktop user$ (user being replaced with your user name). 

We have now successfully navigated to the Desktop within Terminal.

Terminal Commands

Terminal An Apple app that comes with macOS. Terminal provides a window with a command line where you can type commands for the computer's operating system to perform. Terminal is a type of program called "terminal emulator" commonly found on UNIX-based computers.

 

There are a total of 1361 commands available within the terminal.app emulator within macOS 10.14 Mojave.

All are viewable by tapping the 'esc' key 4 times in a new terminal window and then typing 'y'.

Here are the first ten:
