L0059 CE6-related: Simplification on MTS kernel derivation
L0111 CE6-related: Transform Skip Condition on Transform Block size
L0285 Adopt JVET-L0285 (8-bit transform matrices)
L0118 CE6-1.7b: Currently the switching DST-7/DCT-8 is different for inter and intra. Results indicate that the unification has minor impact on performance
L0274 version 7.1.3b Transform coefficient coding with reduced number of regular-coded bins
L0414 Other from the proposal, which makes the QP offset dependent on transfer function, the values shall be signalled in the SPS. Default is not applying (enabling flag=0). If the flag is 1, another syntax element follow indicating the number of intervals (2 bits for 2,3,4,5), and then the luma threshold values and QP offsets between the intervals.
L0410 CE11-related: On deblocking tC table
Meeting notes (L0074) Apply the same logic to VVC (both ATMVP and affine) sub-blocks (on 8x8 grid) as to PU in HEVC deblocking. This means check the deblocking motion conditions for ATMVP and affine motion sub-block boundaries as if they were PUs in HEVC.
L0217 Adopt JVET-L0217 (as per v4), Non-CE1: Relation Between QT/BT/TT Split Constraint Syntax Elements
L0678 QT/BT/TT Split Constraint Syntax Elements Signaling Method
L0081 CE1.2.1: Constraint for binary and ternary partitions
L0361 JVET-L0361 (version with 22 context models) contexts for split
L0553 Adopt second fix to semantics of init_qp_minus26 where +25 is changed to +37
L0293 Adopt CPR with restriction to using current CTU as reference area under condition, non-CTC
L0047 Adopt method 1 as the more consistent and “clean” design (roughly neutral on coding efficiency 0.01%
L0198, L0468, L0104 "use fixed subblock size 8x8 for ATMVP (L0198, L0468, L0104, possibly some others).
check the first spatial neighbouring motion vector and use this as the reference motion vector for the collocated position for motion vector derivation "
L0106, L0158 Reset the FIFO table in each CTU row for HMVP
L0194 use one context for the first bin of the full-block merge index and bypass coding of other bins . for the full-block merge index only at this time, approximately no coding efficiency impact
L0646 Adopt L0646 (0.66% coding efficiency; weighted prediction should also be put in the draft, but this and weighted prediction would be mutually exclusive at the picture level, when used with OBMC the weights of the neigbours would apply for the neighbour predictors, which is how the BMS software already does it, no consideration in deblocking filter
L0104 Prohibit 4x4 bi-prediction for inter CU
L0257 Align the software with the draft text regarding ATMVP motion vector clipping
L0377 Rounding motion vectors toward zero rather than toward minus infinity for AMVR
L0093/L0282 align VTM with draft text regarding the pruning of regular merge list
L0265 set the chroma subblock size to 4x4 instead of 2x2 for affine motion compensation by averaging the MVs of the 4x4 luma subblocks
L0271 Adopt 4.1.6.a (CE4.1.6: Simplification of affine AMVP candidate list construction)
L0045 Adopt 4.1.11.a on line buffer reduction for affine mode (pending consideration of non-CE contributions, text in JVET-L0045 to be checked).
L0632/L0142 Adopt the variation of 4.2.6.d as modified in L0632, pending text adapted from modifying model inheritance of L0368 and cross-check confirmation
L0369/L0055 Adopt 4.2.8 moving ATMVP into the affine merge list (assuming ATMVP operates on a subblock basis, restrict ATMVP mode to CUs of which both the width and height are larger than or equal to 8 (L0055)
L0090 4.4.12.a (0.38% in RA), merge list size 6 (text in L0090)
L0266 Adopt history method with merge list size 6, history applied also to AMVP (0.58% gain in RA, text in L0266).
L0054 Adopt UMVE variant b (1.29% in RA); this needs a better name – e.g., merge with MVD (MMVD)
L0694 CE4-related: Combination of affine mode clean up and line buffer reduction
L0260 Encoder optimization for affine motion estimation
L0100 Adopt CE10.1.1.c (described in JVET-L0100) combined intra/inter with restriction to w×h >= 64 luma samples (0.5% in RA).
L0124/L0208 CE10.3.1.b, Adopt (0.57% in RA, 1.23% in LB), with the L0208 bug fix, flag after combined intra/inter
