Claim 19:
20. A non-transitory computer-readable recording medium storing a bitstream of a video which is generated by a method performed by a video processing apparatus, wherein the method comprises:
determining that a first intra mode is applied on a video block of the video, wherein a process in the first intra mode includes a matrix vector multiplication operation followed by an upsampling operation to generate prediction samples for the video block of the video; and
generating the bitstream based on the determining,
wherein inputs to the upsampling operation include neighboring reference samples of the video block of the video, and
wherein the process in the first intra mode further includes a downsampling operation prior to the matrix vector multiplication operation based on a size of the video block.
