In chapter 7.4.5.4 those values are defined by: ""The variable LumaWeightL0[ i ] is specified by (1 << luma_log2_weight_denom ) + delta_luma_weight_l0[ i ]. When luma_weight_l0_flag[ i ] is equal to 1, the value of delta_luma_weight_l0[ i ] shall be in the range of −128 to 127, inclusive. When luma_weight_l0_flag[ i ] is equal to 0, LumaWeightL0[ i ] is inferred to be equal to 2^luma_log2_weight_denom for RefPicList0[ i ]."" I suspect a typo here. Is the following more accurate ? : ""The variable LumaWeightL0[ i ] is specified by (1 << luma_log2_weight_denom ) + delta_luma_weight_l0[ i ]. When luma_weight_l0_flag[ i ] is equal to 1, the value of '''LumaWeightL0'''[ i ] shall be in the range of −128 to 127, inclusive. When luma_weight_l0_flag[ i ] is equal to 0, LumaWeightL0[ i ] is inferred to be equal to 2^luma_log2_weight_denom for RefPicList0[ i ]."" Same remark for ChromaWeightLX definition.
