Example implementations include a method, apparatus and computer-readable medium of video coding, comprising determining, for a conversion between a video comprising a plurality of pictures and a bitstream of the video, first layer information which is utilized in a first process performed on a first layer of each picture. The implementations further include determining, second layer information which is utilized in a second process performed on a second layer of each picture. Additionally, the implementations further include performing the conversion for the second layer based on the first layer information and the second layer information.
