1. A method for video encoding in an encoder, comprising:
determining that a current block is not coded in an intra block copy (IBC) mode;
responsive to the determination that the current block is not coded in the IBC mode,
determining whether a size of the current block is greater than a threshold; and
encoding a mode prediction flag into a coded bitstream based on the size of the current block being greater than the threshold, the mode prediction flag indicating whether the current block is coded in an intra prediction mode.
