abstract = "Completing standardization of the VVC in July 2020, the Joint Video Experts Team of ISO/IEC SC29/WG05 launched the {"}Beyond VVC{"} exploration by developing the Enhanced Compression Model (ECM) which keeps integrating newly developed advanced encoding tools together.In inter prediction, the Advanced Motion Vector Prediction (AMVP) method encodes motion vectors using Motion Vector Predictor (MVP) selected from MVP candidate list.In the current ECM of version 11.0, unless zero MV is added at the first place into the candidate list while at least one neighboring block has zero MV, zero MV has very low probability to be selected as MVP, thus potentially resulting in reduced coding efficiency.To overcome this limitation, we investigate a method that puts zero MV into the list unless the list is already full so that the zero MV can be subject to MVP refinement and reordering process to improve coding efficiency.Experimental results demonstrate BDBR gain of 0.03\% in the luma channel.",
