- juliobbv 11d agoBy "small", it's meant in a relative sense. JXL's coded blocks can be as big as 64x64, and block boundaries can create visible seams. Example: https://juliobbv.com/pics/photo.jxl https://juliobbv.com/pics/photo.jxl These seams are especially noticeable in the background, and align with coded block edges. You can tell the encoder is trying to conceal them as best as it can, but this cannot be properly mitigated without a proper deblocking filter. For comparison, AV1 tiles normatively go through the deblocking filter.
