Candidate depth levels for each RQT type.
| | RQT type | Depthpred | Depth range
depthmin, depthmax | TU size |
| | Type 0 | Depthpred ≤ 1 | | 32 × 32 | | Type 1 | 1 < depthpred ≤ 1.5 | | 32 × 32~16 × 16 | | Type 2 | 1.5 < depthpred ≤ 2.5 | | 32 × 32~8 × 8 | | Type 3 | 2.5 < depthpred ≤ 3.5 | | 16 × 16~4 × 4 | | Type 4 | Depthpred > 3.5 | | 8 × 8~4 × 4 |
