Abstract
Video production equipment uses different codecs and settings to balance competing requirements, such as trading off between bitrate and quality. The introduction of ultrahigh-definition television (UHDTV) and high dynamic range (HDR) adds to the number of codec implementations, making codec choices harder. To help their members evaluate the visual quality of new video production codecs, the European Broadcasting Union (EBU) and the Institut für Rundfunktechnik (IRT) have organized expert viewings of the latest production codecs. Based on the plans revealed at International Broadcasting Convention (IBC) 2019, more than 200 possible codec configurations were identified. After a voting round by broadcasters, more than 40 of these configurations were selected for actual testing. The focus was on real-world products, not laboratory prototypes. Seven generations were encoded for each configuration. The peak signal-to-noise ratio (PSNR) of all sequences was calculated. Subsequently, the first, fourth, and seventh generation of each sequence was scored by expert viewers. The results indicate, that overall, the tested codec configurations perform well up to the seventh generation. For some of the algorithms, a small quality degradation was seen in noise behavior and spatial resolution but no difference in dynamic range was noticeable. There is a small discernible difference in the performance for the different transfer functions.

bio
Dagmar Driesnack, Dipl. Ing. (FH), graduated with a degree in media technology from the University of Applied Sciences, Mittweida, Germany. In 2006, she joined the Institut für Rundfunktechnik GmbH (IRT), Munich, Germany, as a research engineer and worked in the AV Technologies department as a senior expert. She has led the project “Future Video” at IRT focusing on ultrahigh-definition (UHD) and its aspects for acquisition, production, and distribution. She chaired various groups at the European Broadcasting Union (EBU) and is currently the chair of the EBU’s Video Systems Group (project group of strategic program production). She is also a member of the Digital Video Broadcasting (DVB) project, SMPTE, and the Fernseh- und Kinotechnische Gesellschaft (FKTG).
Frans de Jong
bio
Frans De Jong holds a master’s degree in information theory from Delft Technical University, Delft, The Netherlands, where he focused on keyframe-extraction algorithms for video-indexing. He has worked in the media industry all his life, both in hands-on (video editor, broadcast engineer) and in development roles (system architect and technical consultant). Since 2003, he has been a senior engineer at the EBU Technology & Innovation Department, Geneva, Switzerland, where he has worked on production topics ranging from access services to loudness (EBU R 128). He coordinates the EBU strategic program on production and the EBU Video Systems Group. His current focus is on UHD, high dynamic range (HDR), and cloud production. He is a SMPTE Fellow.
