Codecs may be modified to consider weighting and/or illumination compensation parameters when determining a deblocking filter strength that is to be applied. These parameters may be useful for recording illumination changes, such as fades, cross-fades, flashes, or light source changes, which allows these illumination changes to displayed during playback using the same reference frame data which different weighting and/or illumination compensation parameters applied. In different instances, the parameters may be considered when setting a deblocking filter strength to ensure that these effects are properly displaying during playback while minimizing the appearance of blocking artifacts.
