摘要：
A method of video processing is provided to include: maintaining, prior to a conversion between a current video block of a video region and a coded representation of the video, at least one history-based motion vector prediction (HMVP) table, wherein the HMVP table includes one or more entries corresponding to motion information of one or more previously processed blocks; and performing the conversion using the at least one HMVP table; and wherein the motion information of each entry is configured to include interpolation filter information for the one or more previously processed blocks, wherein the interpolation filter information indicates interpolation filters used for interpolating prediction blocks of the one or more previously processed blocks.
