In various embodiments, a technique for reducing banding artifacts in decoded video data includes receiving a first block of reconstructed samples associated with a frame of encoded video data, applying a first filter to a first reconstructed sample included in the first block of reconstructed samples to generate a first filtered sample, determining that a first randomized dithering operation associated with the first filter is has been activated, applying the first randomized dithering operation to the first filtered sample to generate a first dithered sample, and generating a first portion of decoded video data based on the first dithered sample.
