Methods and apparatus for video processing are disclosed. The processing may include video encoding, video decoding, or video transcoding. One example method includes performing a conversion between a video including a picture including one or more slices and a bitstream of the video. The conversion conforms to a rule that specifies that whether a deblocking filter is applied to the one or more slices referring to a picture parameter set is based at least on a first syntax element included in the picture parameter set. The first syntax element indicates whether the deblocking filter is disabled for the picture.
