There can be many 8K file-based or live workflows. Such workflows will vary based on budget, content production needs, hardware and software preferences or availability and comfort level with certain processes. In this section we will graphically profile some of these workflows.
File-based 8K Workflow
Below is the file-based 8K workflow developed by independent filmmaker Roman Hill. As viewed in the below graphic, the workflow is very straightforward as there are no special effects or other capture or production considerations. Such a workflow can thus easily be adopted by many independent filmmakers.
Live 8K Workflow
In December 2020 a number of technology companies have come together to demonstrate 8K live streaming over the Internet. The demonstration consisted of an end-to-end 8K live video showcase from live production to encoding, streaming and playback on 8K TVs.
Intel, NHK Technologies, Poznan Supercomputing and Networking Center – PSNC, Spin Digital, and Globo were supported by Sony, Astrodesign, and Zixi in the event.
The demonstration presented a viable workflow for 8K live streaming over the Internet and included 4 main technology components:
- 8K live production system with multiple cameras and live switching and mixing
- HEVC real-time encoder with low-latency and broadcast-grade quality 8K video at low bitrate
- Low-latency live streaming over the public Internet
- 8K HEVC software decoder and media player for 8K TVs with HDMI 2.1 interface
The 8K live TV program was produced at the PSNC’s 8K studio in Poznan (Poland), with the video signal encoded using Spin Digital’s HEVC encoder and streamed to multiple locations across the world where it was received live and played on 8K screens. Viewing locations included NHK Technologies in Tokyo, Globo in Rio de Janeiro, Intel in Portland Oregon, and Spin Digital in Berlin (Figure 1).
