1. A method of processing visual media data, the method comprising:
performing a conversion between a visual media file and a bitstream of visual media data according to a format rule, wherein
the bitstream includes a block of the visual media data encoded based on an intra prediction angle corresponding to an intra prediction mode that is a directional intra prediction mode and not a planar intra prediction mode, the intra prediction angle being (i) beyond a bottom left direction 45 degrees from horizontal mode, or (ii) beyond a top right direction 45 degrees from the horizontal mode, and
the bitstream includes the intra prediction mode based on a predetermined plurality of intra prediction modes and a corresponding predetermined plurality of intra prediction angles, the intra prediction mode corresponding to the intra prediction angle of the block.
