Abstract: A video coding device selects a current block for sub-block based affine inter-prediction, and derives a sub-block size for a sub-block of the current block. The sub-block size includes a sub-block width and a sub-block height. The device determines a unidirectional width threshold (TwU), a bidirectional width threshold (TwB), a unidirectional height threshold (ThU), and a bidirectional height threshold (ThB), where a total value of TwB and ThB exceeds a total value of TwU and ThU. The device determines that the affine inter-prediction is unidirectional inter-prediction or bidirectional inter-prediction. Based on the determination, the device applies the TwU or the TwB to the sub-block width, and applies the ThU or the ThB to the sub-block height. The device then derives a motion vector for the sub-block based on motion vectors for the current block, the sub-block width, and the sub-block height.
