1. A method of processing video data, comprising:
determining, for a first conversion between a first video block of a video and a bitstream of the video, a first indication, wherein the first video block is coded using an inter mode;
inferring, in response to the first indication indicating the first video block being divided into multiple first sub-blocks, a second indication for at least one first sub-block, wherein the second indication is not included in the bitstream and is inferred to indicate whether a luma component of a corresponding first sub-block includes non-zero coefficient values; and
performing the first conversion at least based on the second indication.
