JVET-AF0047 [AHG4] ECM10.0 evaluation on V3C test content [S. Schwarz, M.M. Hannuksela (Nokia)]
This document provides performance evaluations of the latest ECM version on volumetric video-based coding (V3C) video test sequences. When compared to ECM8.0, ECM10.0 shows improvements for MPEG immersive video (MIV) content, whereas there is a moderate loss in RA conditions and a moderate gain in AI conditions for video-based point cloud coding (V-PCC) content. Comparing the BD-rate of ECM against VTM, a smaller bitrate reduction is obtained with V3C content than with the content classes of the common test conditions.

It is noted that the gain of ECM vs. VTM is comparably lower for V-PCC content than for CTC classes. However, the same is the case in a comparison of VTM vs. HM.
