Where do compression artifacts come from?
Compression artifacts are small errors that result in the decompressed signal when a digital signal is compressed with a high compression ratio. These errors are known as "artifacts," or unwanted defects. The artifacts may resemble noise (or edge "busyness") or may cause parts of the picture, particularly fast moving portions, to be displayed with the movement distorted or missing.
