1. A method for video encoding in an encoder, comprising:
responsive to a current block in a current picture being coded in matrix based intra prediction (MIP),
determining an MIP mode index for the current block, the MIP mode index indicating one of a plurality of MIP modes;
responsive to the current block not being coded in MIP and a first neighboring block of the current block being coded in MIP,
determining an intra prediction candidate mode for the current block to be a Planar intra prediction mode; and
encoding the current block according to (i) the one of the plurality of MIP modes in response to the current block being coded in MIP and (ii) the Planar intra prediction mode in response to the current block not being coded in MIP and the first neighboring block of the current block being coded in MIP.
