Abstract: In some embodiments, a method receives a first image and a second image for a comparison of film grain. The first image and the second image are converted from a spatial domain to a frequency domain to generate a first frequency domain representation for the first image and a second frequency domain representation of the second image. The method compares a first distribution of frequency components from the first frequency domain representation to a second distribution of frequency components from the second frequency domain representation. A score for an assessment of differences of the film grain in the first image and the second image is generated based on the comparing.

Abstract: In some embodiments, a method analyzes flagged locations from a plurality of locations in an encoding of a video to form a cluster of locations. Draft micro-chunk boundaries for the cluster are determined based on searching for a first start location and a first end location in the encoding. The method searches in a first search range before the first start location and a second search range after the first end location for a second start location in the first search range and a second end location in the second search range. The second start location and the second end location form a micro-chunk. An encoding parameter set is determined for the micro-chunk formed by the second start location and the second end location based on content characteristics of the micro-chunk. The method uses the encoding parameter set to encode the micro-chunk for insertion in the encoding of the video.
