Enc_video_qmin setting question

Based on the name of this setting, I’m pretty certain this is related to video quality, but I’m not sure if it just sets a bitrate floor or actually affects the algorithm, or both.

Would someone care to illuminate how this setting works, and what the range of legal values are?

Thanks very much

It has been explained to you as best as possible.
