AHG4: Experiments in preparation of scalable quality ladder visual testing
Abstract
This document reports about some experiments in preparation of VVC multilayer verification tests planned in JVET-AD2021, especially the 2nd test category involving a quality ladder, and more specifically the definition of the anchor. Encodings at candidate resolutions and overlapping bit rates were performed, PSNR and VMAF metrics of upscaled decoded pictures are reported, along with visual checks to estimate expected scores and to compare resolutions at comparable bitrate. The intent is to provide data to help define rate points and resolutions of the above-mentioned anchor.

There was a large variety of material, not all visually assessed yet.
Informal viewing for rough pre-selection was planned for Tuesday.
