1. A method of video encoding, comprising:
determining, by processing circuitry of a video encoder, that a coded video bitstream conforms to one of a Main 10 still picture profile or a Main 4:4:4 10 still picture profile;
generating profile information for a plurality of image slices to be included in the coded video bitstream, the profile information indicating that each of the image slices is to be intra coded and indicating the one of the Main 10 still picture profile or the Main 4:4:4 10 still picture profile;
constraining only one picture to be included in the coded video bitstream according to the one of the Main 10 still picture profile or the Main 4:4:4 10 still picture profile;
performing intra prediction on each of the image slices; and
encoding the picture based on the intra prediction and according to the one of the Main 10 still picture profile or the Main 4:4:4 10 still picture profile to form the coded video bitstream.
