8K and macOS

macOS Mojave 10.14.4 Beta 18E194d

MacBook Pro (15-inch, 2018)

Processor 2.9 GHz Intel Core i9

Memory 32 GB 2.4 GHz DDR4

Graphics Radeon Pro 560X 4 GB, Intel UHD Graphics 630 1.5 GB

UHD 8K (7680x4320p60) Quicktime X (10.5) Playback.

All ProRes: No

H.264: 8K not supported

H.265 8-bit: Davinci Resolve hangs

H.265 10-bit: Too long to render in DaVinci Resolve

8K and a Beta release of macOS clearly do not mix. The good news is that the AMD WX9100 is fully utilized during 4K HEVC H.265 rendering within Davinci Resolve 15.2.4.

Quicktime X on the other hand shows neither CPU nor GPU using while exporting the HEVC, leading to the idea that some hyper efficient hardware acceleration is implemented well between macOS and the Intel chip.

Rooibus

Aspalathus linearis meaning "red bush”; is a broom-like member of the Fabaceae family of plants growing in South Africa’s fynbos.

The leaves are used to make a herbal tea that is called by the names: rooibos, bush tea (especially in South Africa), or redbush tea (predominantly in Great Britain). The tea has been popular in South Africa for generations, but is now consumed in many countries worldwide. It is sometimes spelled rooibosch in accordance with the original Dutch. The tea has a taste and color somewhat similar to hibiscus tea, or an earthy flavor like yerba mate.

The generic name comes from the Greek name aspalathos for Calicotome villosa, which has very similar growth and flowers to the rooibos plant. The specific name of linearis comes from the plant’s linear rowing structure and needle-like leaves.

Fynbos; (meaning fine-leaved plants) is a small belt of natural shrubland or heathland vegetation located in the Western Cape and Eastern Cape provinces of South Africa. This area is predominantly winter rainfall coastal and mountainous areas with a Mediterranean climate. The fynbos ecoregion is within the Mediterranean forests, woodlands, and scrub biome. In fields related to biogeorgraphy, fynbos is known for its exceptional degree of biodiversity and endemism, consisting about 80% (8,000 fynbos) species of the Cape floral kingdom where nearly 6,000 of them are endemic. This land has faced severe threats and still does, but due to the many economic uses conservation efforts are being made to help restore it.

Endemism is the ecological state of a species being unique to a defined geographical location, such as an island, nation, country or other defined zone, or habitat type; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. The extreme opposite of endemism is precinctive, which applies to species (and subspecific categories) that are restricted to a defined geographical area.

DVX200 Bitrate

I’m not a fan of the small Micro Four Thirds sensor size (yet I put my preorder in for the Blackmagic Pocket Cinema Camera 4K which is just that) but still the Panasonic DVX200 is quite the capable camera. Looking a couple of years back, this was and pretty much still is the cheapest fixed lens video camera that supports 4K60p. With a constant f/2.8 aperture throughout the zoom, you’d be very and I mean very hard pressed to find an interchangeable lens camera + 13x zoom lens combo at the $3.5K price point.

Here’s a quick rundown of the internal bitrates:

2160p59.94 = 18.75MB/s = 1.125GB/m = 67.5GB/h

1080p59.94 = 12.5MB/s = 0.75GB/m = 45GB/h
