8K-UHDTV Production Equipment and Workflow which Realize an Unprecedented Video Experience

NHK has developed equipments and facilities for 8K-UHDTV production such as cameras, recorder-players, OB trucks, editing rooms, and so on. We have started 8K test broadcasting on August 1st 2016, so it is becoming mainstream for us to produce spectacular content using HDR( High Dynamic Range) and WCG ( Wide Color Gamut) technologies. This paper describes 8K content production equipment and workflow with HDR and WCG technologies. A new single-chip color 8K camera can capture high-quality video clips with HDR and WCG, and the compact 8K recorder can record and play them. The latest 8K editing system with a color grading function can input and output the 8K clips in real-time. In the design of the total system, we have considered how to keep the 8K qualities when importing and exporting in an editing workflow.
