1. A method for video processing, comprising:
determining, for a conversion between a current block of a video and a bitstream of the video, whether multiple flags of the current block are presented in the bitstream based on whether a same dimension condition associated with a size of the current block is satisfied; and
performing the conversion based on the determining,
wherein whether a skip flag indicating whether a skip mode is used for the current block and a flag indicating whether an inter prediction mode is used for the current block are presented in the bitstream are both based on the same dimension condition that a width of the current block is equal to 4 and a height of the current block is equal to 4;
wherein a context increasement used for coding an inter prediction direction flag is equal to a fixed integer number that is not a function of a width or a function of a height of the current block in response to a sum of the width and the height of the current block being 12, and
wherein in response to the size of the current block being 8×4 or 4×8, a weight index is set to 0 for the current block, and wherein the weight index is used to find weights from a weight set to generate a weighted sum from prediction samples of list 0 and list 1.
