-aq-mode <int> E…V… adaptive quantization mode (from -1 to 4) (default -1)

none E…V… Aq not used

variance E…V… Variance based Aq

complexity E…V… Complexity based Aq

cyclic E…V… Cyclic Refresh Aq

These are the options I get in FFmpeg, however I don’t know in what mode it should be used, or how to properly use it, any input would be highly appreciated.
