Set target quality level (0 to 51, 0 means automatic) for constant quality mode in VBR rate control (from 0 to 51) (default 0) AQ strength scale is from 1 (low) - 15 (aggressive) (from 1 to 15) (default 8) When Spatial AQ is enabled, this field is used to specify AQ strength. Set 1 to minimize GOP-to-GOP rate fluctuations (default false) Set this to 1 to enable automatic insertion of non-reference P-frames (default false)

Set 1 to indicate zero latency operation (no reordering delay) (default false) set to 1 to enable Temporal AQ (default false) set to 1 to enable Spatial AQ (default false) When lookahead is enabled, set this to 0 to disable adaptive B-frame decision (default true) If forcing keyframes, force them as IDR frames. When lookahead is enabled, set this to 1 to disable adaptive I-frame insertion at scene cuts (default false) Delay frame output by the given amount of frames (from 0 to INT_MAX) (default INT_MAX)
