![]() ![]() ![]() The Aliens Blu-ray is one which stood out as having this "look". I believe this is the same process which has been used in many Blu-ray or 4K remasters: remove the coarse film grain, and replace it with finer/higher resolution noise. It dramatically changed the appearance of the image. Adding higher resolution noise prevented it from looking like all the detail had been stripped out, and gave the impression that it could have been sourced from a slightly fuzzy Blu-ray rather than a DVD. I don't have any examples to hand, but I was recently doing some work upscaling some old DVD content and by denoising the image, upscaling, then adding grain on top, the appearance was significantly improved.ĭenoising the image was important for removing artifacts, but gave it an ugly artificially-smoothed-over look. Adding noise to the image can increase the apparent detail as well.
