JVET-L0618 CE5-related: CE5.1.6 (JVET-L0115) with 10 and 14 bits probability precision for short and long windows [A. Said, J. Dong, H. Egilmez, Y.-H. Chao, M. Karczewicz, V. Seregin (Qualcomm)] [late]

This contribution reduces the probability precision used in CE5.1.6 (i.e., JVET-L0115) from 30 bits to 24 bits. Under the CE5 test conditions, the average coding gains are -0.10% AI, -0.38% RA, and -0.21% LDB. Compared with BMS2.0.1 VTM configuration, the average coding gains are -1.02% AI, -0.88% RA, and -0.81% LDB.

The performance drop in RA was 0.05% on average.

This was included in the complexity analysis of the BoG JVET-L0692.
