This contribution reports the results of EE2 Test 4.5a and Test 4.5b on Multiple Transform Set Selection (MTSS) applied to explicit intra MTS, initially presented in the contribution JVET-AH0307. In this proposal, an alternative primary transform set from the explicit intra MTS lookup-table is considered in addition to the initial primary transform set for DIMD, TIMD, IntraTMP, MIP and EIP.
