Hi
Ok I did a couple of picture by picture comparisons after extraction frames via Virtualdub. aq-mode=2 does reduce noise and smooths the image compared to AQ1, that is why AQ1 uses more bitrate at a given CRF. It was more noticeably in backgrounds than in foreground object (i.e. faces). I am not certainif one can see it while playing the movie. Nevertheless since I want a high quality encode I will go with aq1 for now. |

Code:
--aq-mode <0|1|2|3|4> Adaptive Quantization operating mode. Raise or lower per-block quantization based on complexity analysis of the source image. The more complex the block, the more quantization is used. This offsets the tendency of the encoder to spend too many bits on complex areas and not enough in flat areas. 0: disabled 1: AQ enabled 2: AQ enabled with auto-variance (default) 3: AQ enabled with auto-variance and bias to dark scenes 4: AQ enabled with auto-variance and edge information |
