Abstract

This application is directed to coding video data that includes a plurality of image samples of a video frame. Each image sample corresponds to one of a luma sample and a chroma sample. Each image sample is filtered using an adaptive in-loop filter having a filter length and a set of filter coefficients. A set of related image samples are identified in the filter length of each image sample. For each related image sample, a respective clip value index and a corresponding filter coefficient are identified. A difference of each related image sample and the respective image sample is clipped based on the respective clip value index that corresponds to a respective clipping boundary value equal to 2 to a power of a respective clipping number. The respective image sample is modified with the clipped difference of each of the related image samples based on the respective filter coefficient.
