In a video processing system, a method and system for equalizing video quality using selective re-encoding are provided. Increasing the occurrence frequency of intra-coded pictures may improve video encoding quality by optimizing a target bit-budget for a specified group-of-pictures structure. Selected predictive and/or bidirectional-predictive pictures may be re-encoded as virtual intra-coded pictures to increase the occurrence frequency of intra-coded pictures. The virtual intra-coded pictures may not be placed in a bit stream output but may be utilized to generate statistical information to determine the frequency of occurrence of available picture coding types. The generated statistical information may be utilized to modify a target picture bits estimation model and may be also be utilized by a picture quality equalizer to configure a selective re-encoding path for re-encoding the selected pictures.
