    "abstract": "We developed an ultrahigh-definition (UHD)-2/8K camera recorder that uses a complementary metal–oxide semiconductor (CMOS) image sensor with an organic thin-film, instead of photodiodes for the opto-electrical conversion element. The advent of UHD-2/8K Super Hi-Vision broadcasts and an increase in the production of UHD-2/8K programs across a variety of genres necessitate the development of a sensor with a good signal-to-noise ratio (SNR) and high-dynamic range (HDR) to capture the full range of HDR video. To ensure successful use of this sensor, we studied the level diagrams (e.g., balancing of sensitivity, SNR, and dynamic range) that would best fit the sensor’s characteristics and use its strengths, and then proceeded accordingly. For the current UHD-2/8K location shooting, a workflow is needed to record raw data and post-process them into a practical video format. To implement a more efficient workflow, we chose to use Grass Valley HQX compression encoding while adding features that make it possible to store video data in a compressed form and simultaneously generate high-definition television (HDTV) proxy data. The workflow that we envisioned uses proxy data for offline editing and relinks them using online editing equipment.",
