Abstract: Systems, devices, and methods of performing inter-frame prediction in video compression. A method includes: partitioning a video frame into superblocks, each superblock includes a plurality of macroblocks; determining an upper boundary on attributes that are associated with residual blocks of the plurality of macroblocks, based on pre-defined constraints on the total number of bits allocated for motion vector descriptions in a superblock; for each macroblock in a superblock, determining a partition size and a motion vector resolution which yield, for all macroblocks in the superblock, a motion vector description and a corresponding residual with attributes less than or equal to the upper boundary.

Abstract: Aspects of the disclosure provide a method for forming patch groups. The method can include determining a list of K motion vectors (MVs) for each current patch to form a patch group that includes the respective current patch and K reference patches corresponding to the K MVs, wherein the current patches are included in a reconstructed picture. The list of K MVs of a first current patch that is one of the current patches is determined by performing a neighbor-based fast search (NBFS) process. The NBFS process can include selecting K MVs from lists of K MVs of at least one neighboring current patch of the first patch to form a first list of K MVs of the first current patch, and performing a first refinement process to obtain a second list of K MVs of the first current patch based on the first list of K MVs.

Abstract: A system for providing improved video quality and compression efficiency during encoding by detecting video segments having film grain approaching the "Red Lady" problem. The system detects when film grain approaches the level of the "Red Lady" problem by measuring frame-by-frame temporal differences (ME scores). From the ME scores, two key indicators are identified: (1) The average temporal difference in frames with an intermediate motion level higher than frames of non-noisy video; and (2) The fluctuation of the temporal differences between frames in a group is very small. When these indicators identify a high film video, a signal is provided to an encoder which allocates less bits to I frames and more bits to P and B frames than for other frames of video without comparable film grain.

Abstract translation: 一种用于通过检测具有接近“红女士”问题的胶片颗粒的视频片段来在编码期间提供改善的视频质量和压缩效率的系统。 系统通过测量逐帧时间差异（ME分数）来检测胶片颗粒何时接近“红女士”问题的水平。 从ME得分，确定了两个关键指标：（1）中间运动水平高于非嘈杂视频帧的帧的平均时间差; 和（2）一组中帧之间的时间差异的波动非常小。 当这些指示符识别高胶片视频时，将信号提供给编码器，其向I帧分配较少的比特，并且向P和B帧分配比对于没有可比胶片颗粒的其他视频帧的比特。
