Abstract: Embodiments of a coding unit division decision method and device, an encoder and a storage medium are disclosed. The method includes: determining the current level of a target CU and obtaining a predicted level of the target CU according to a preset level prediction rule; determining whether the current level is smaller than the predicted level; in case of the current level smaller than the predicted level, performing division decisions on sub-CUs of the target CU to obtain first division decision results; in case of the first division decision results meeting a preset first skip condition, determining that a division decision result for the target CU is a result comprised of a division result for dividing the target CU into the four sub-CUs and the first division decision results respectively corresponding to the four sub-CUs of the target CU.
