Abstract
Indication of usage of the half-pel switchable interpolation filter is signalled in AMVP mode and inherited in regular merge mode and MMVD mode. However, the indication may be true even if the CU only has MV components with finer precision than half-pel, which is asserted to be logically incorrect. This contribution proposes to set the indication to false in such cases. Simulation results reportedly show that the proposed method has negligible impact on the coding performance.

JVET-P0490 Non-CE4: Cleanup of half-pel switchable interpolation filter [H. Liu, N. Zhang, L. Zhang, K. Zhang, Z. Deng, J. Xu (Bytedance)]

Abstract
This contribution is a crosscheck report of JVET-P0490 (Non-CE4: Cleanup of half-pel switchable interpolation filter). The simulations were carried out based on the common test condition (CTC). Based on the partial results, the test results are matched, unless the running time is not reliable for Class A1 and A2.

Abstract
A crosscheck of JVET-P0490 has been carried out for the CTC test set. It was reported that BDR figures match for all three test configurations (AI, RA, LDB). Decoder run times were also crosschecked and were found to match as well.

Abstract
The goal of this Core Experiment (CE) is to improve and/or enhance cross component loop filtering (CC-ALF) techniques. These CC-ALF techniques will be evaluated according to both subjective and objective metrics.

Future meeting plans, expressions of thanks, and closing of the meeting
Future meeting plans were established according to the following guidelines:
Meeting under ITU-T SG 16 auspices when it meets (ordinarily starting meetings on the Tuesday of the first week and closing it on the Wednesday of the second week of the SG 16 meeting – a total of 9 meeting days), and
Otherwise meeting under ISO/IEC JTC 1/SC 29/WG 11 auspices when it meets (ordinarily starting meetings on the Tuesday prior to such meetings and closing it at lunchtime on the last day of the WG 11 meeting – a total of 9.5 meeting days).
In cases where an exceptionally high workload is expected for a meeting, an earlier starting date may be defined. For the upc...
