| // Coefficient scaling and quantization with AV1 TX are tailored to |
| // the AV1 TX transforms. Regardless of the bit-depth of the input, |
| // the transform stages scale the coefficient values up by a factor of |
| // 8 (3 bits) over the scale of the pixel values. Thus, for 8-bit |
| // input, the coefficients have effectively 11 bits of scale depth |
| // (8+3), 10-bit input pixels result in 13-bit coefficient depth |
| // (10+3) and 12-bit pixels yield 15-bit (12+3) coefficient depth. |
| // All quantizers are built using this invariant of x8, 3-bit scaling, |
| // thus the Q3 suffix. |
| |
| // A partial exception to this rule is large transforms; to avoid |
| // overflow, TX blocks with > 256 pels (>16x16) are scaled only |
| // 4-times unity (2 bits) over the pixel depth, and TX blocks with |
| // over 1024 pixels (>32x32) are scaled up only 2x unity (1 bit). |
| // This descaling is found via av1_tx_get_scale(). Thus, 16x32, 32x16 |
| // and 32x32 transforms actually return Q2 coefficients, and 32x64, |
| // 64x32 and 64x64 transforms return Q1 coefficients. However, the |
| // quantizers are de-scaled down on-the-fly by the same amount |
| // (av1_tx_get_scale()) during quantization, and as such the |
| // dequantized/decoded coefficients, even for large TX blocks, are always |
| // effectively Q3. Meanwhile, quantized/coded coefficients are Q0 |
| // because Qn quantizers are applied to Qn tx coefficients. |
| |
| // Note that encoder decision making (which uses the quantizer to |
| // generate several bespoke lamdas for RDO and other heuristics) |
| // expects quantizers to be larger for higher-bitdepth input. In |
| // addition, the minimum allowable quantizer is 4; smaller values will |
| // underflow to 0 in the actual quantization routines. |
