1. A method of decoding video data, the method comprising:
determining a set of multiple transform selection (MTS) candidates for a current block of video data,
wherein determining the set comprises selecting the set, based on a number of non-zero coefficients of a transform block, between
a first set consisting of a single MTS candidate,
a second set of MTS candidates having at least four MTS candidates, and
a third set of MTS candidates having more MTS candidates than the second set, the MTS candidates of the second and third set being MTS candidates other than a DCT2 candidate;
determining one of the MTS candidates of the determined set of MTS candidates for the current block;
inverse transforming the transform block for the current block using the determined one of the MTS candidates to produce a residual block; and
decoding the current block using the residual block.
