FIELD: video coding and decoding.
SUBSTANCE: digital video encoding method is provided that includes determining whether to use, for conversion between a current video block and a video bitstream, a first linear optimization model for conversion using a first encoding mode, wherein the first linear optimization model is derived from a second linear optimization model, which is used for conversion using the second encoding mode, and performing, based on the determination, the conversion. Another method involves determining whether to use, for conversion between the current video block and the video bitstream, a gradient value calculation algorithm for the bidirectional optical flow tool, and performing the conversion based on the determination.
EFFECT: increase of efficiency of encoding/decoding.
