To videophiles, however, YIFY was a source of frustration. Their aggressive compression inevitably introduced visible artifacts like banding (in smooth gradients), blocking (in dark areas), and a general "mushiness" that erased fine film grain. The audio was often compressed to a low-bitrate AAC stereo or 5.1 track, lacking the dynamic range of a lossless Blu-ray soundtrack. A 992 MB file, for some, will always be too small to properly represent a complex, visually rich film like Eyes Wide Shut .
