# fast_pskip Performs early skip detection in P-frames (default: enabled).  This usually improves speed at no cost, but it can sometimes produce artifacts in areas with no details, like sky.
# nr=<0-100000>   Noise  reduction, 0 means disabled.  100-1000 is a useful range for typical content, but you may want to turn it up a bit more for very noisy content (default: 0).  Given its small impact on speed, you might want to prefer to use this over filtering noise away with video filters like denoise3d or hqdn3d.
