SQ_WEIGHT determines if the evaluation of HA, HB, VA, VB, H4 and V4 shapes could be skipped based on the cost of SQ, H and V shapes. Specifically:
-
skip HA, HB and H4 if (valid SQ and H) and (H_COST > (SQ_WEIGHT * SQ_COST) / 100)
-
skip VA, VB and V4 if (valid SQ and V) and (V_COST > (SQ_WEIGHT * SQ_COST) / 100)
-
The lower the SQ_WEIGHT, the higher the chance to skip NSQ
SQ_WEIGHT = Base + Offset
Base = f(Preset)
| Preset(s) | BASE |
|---|---|
| MR | ∞ |
| M0 | 105 |
| M1 | 105 |
| M2 | 100 |
| M3 & beyond | 95 |
Offset = f (Target Shape, Block/PIC Type, Coeff Info, QP)
