So, the critical data rate at which artifacts become visible depends on the nature of the content as described above. If the bit rate is set too low, the images will first become slightly blurry or soft (not visually lossless) before more annoying compression artifacts become visible. Due to the fact that JPEG 2000 doesn’t use a block structure like MPEG-x, no blocking artifacts will occur with D-Cinema.
