In a video processing system, a method and system for parametric video quality equalization in selective re-encoding are provided. A frequency of compression occurrence for a picture coding type may be compared to a threshold level to determine whether virtual encoding through selective re-encoding is to be enabled. A current picture may be encoded using picture coding type N and may be re-encoded using picture coding type M when selective re-encoding is enabled. Bits, distortion, and quantizer scales from a re-encoded picture may be matched to corresponding values in previously re-encoded pictures to generate at least one compression variation parameter alpha or at least one information parameter beta. Parameters alpha or beta may be compared to corresponding threshold levels to determine whether a signal may be sent to enable a selective re-encoding path for generating virtually encoded pictures and increase the frequency of compression occurrence.
