Video editing is an often cumbersome task due to the variety of issues that can arise during the process. These can range anywhere from the editing computer behaving a bit erratically while editing, freezing from time to time, to the system completely shutting down resulting in lost files and wasted hours of work. These issues can occur due to several reasons related to hardware such as a shortage of memory, low storage space, or a bottlenecked CPU. However even when the computer is stable, editors often complain of experiencing choppy or delayed playback when monitoring and reviewing their work.
As this is the current reality for many in the world of editing, we can imagine that as the priority for video has changed in the direction of 4K and is continuing to move towards 8K, these problems aren’t easily disappearing and may, in fact, be occurring more often. Moreover, as the demand grows for 8K mediums in particular, the need for 8K content, and therefore 8K editing, will push those in editing to seek new avenues to solve these issues.
Despite these issues, the industry is slowly embracing the idea of 8K and for good reason. Display devices are becoming larger in size to create stunning experiences for audiences. When displaying images on a screen that is, for example, over 150 inches, viewers will easily be able to point out the jaggedness caused by a low-resolution video source. For this reason, requirements for content resolution has shifted to 4K and it will move to 8K in the near future.
Beside the fact that 8K quality appeals to us visually, there are countless other reasons for its use. There is more flexibility for image stabilization or panning and zooming to reframe a shot without losing image quality in the final 4K delivery format. For visual effects integration, high resolution can provide more detail for tracking or keying since it provides artists with more data to pull from to create their shots. Down sampling high-resolution video can also help reduce noise, as well as maintain a high level of quality.
The most important aspect to plan for is ensuring that your tools and infrastructure can handle the larger resolution and data size that comes along with 8K images. 8K video editing requires both compatible hardware and software. Just like the challenge post-production houses faced when they moved their capabilities from HD to 4K, the main challenge of working with 8K is moving larger files through each step of the workflow. The change is the same given that 4K data is four times the size of HD data, and 8K is four times the size of 4K. To work with 8K, you need to make sure your CPU, GPU, memory, and storage are all capable of handling the upsurge of data. To manage these challenges, the Tamazone Workstation has been designed and tested from the ground up to offer native 8K editing capability.
There are many software applications capable of dealing with 8K video today, from editorial to grading, as well as creative finishing. Examples of these include Adobe Premiere Pro, Blackmagic’s DaVinci Resolve, Autodesk Flame, etc. These programs are capable of handling 8K as CUDA, OpenCL or OpenGL have been written into their applications to harness the power of the GPU.
(1) Dual Intel® Xeon® processors with up to 56 cores and 96 PCIe lanes. For video editing, more cores mean more processing power which translates into faster video editing performance. (As some software have limitations to the CPU core usage, this may not always apply.)
(2) Large-capacity main memory (max 6TB, 256GB DDR4-2666 card x 24). With its large-capacity main memory, approximately 16 minutes of uncompressed 8K data can be buffered (60,000 frames, 1 frame ≈ 100MB).
(3) Supports up to 16 NVMe SSDs (max 256TB SSD x16). With 8K files that may require up to 4.6 TB of storage for one hour of media, it is apparent that handling this type of data requires substantial storage capacity. NVMe significantly improves both random and sequential performance. The net result is faster access to data and improved utilization of drives for video editing. Furthermore, users can reap the benefits of using uncompressed data which does not require the use of CPU or GPU resources for decoding and experiences no loss of color information due to conversion of YUV and RGB color spaces.
(4) A custom-designed motherboard utilizing a PCIe switch on the NVMe SSD side rather than the PCIe slot side to prevent slowdown in video transfer speed. This feature is crucial to a smooth and accelerated editing process for heavy 4K and 8K data. Tamazone Workstation’s configuration theoretically allows for 4 streams of uncompressed 8K 422 video.
(5) Various interfaces including Thunderbolt™3 which allows for theoretical transfer speed of 40Gbps enabling high speed transfer of video content between external storage devices necessary to store 4K/8K video content.
*Thunderbolt™3, though currently functional on Tamazone workstation, is not officially supported by Intel® Xeon® processors. There is a possibility that the Thunderbolt™3 interface may not function with Intel’s future firmware and/or software updates, as well as some Thunderbolt™3 storage devices.
