LCEVC brings a new approach to video compression. It leverages a base video codec such as AVC, HEVC, VP9, EVC, AV1 etc. and employs a highly efficient and low complexity enhancement that adds up to two layers of encoded residuals that correct artefacts produced by the base video codec and add detail and sharpness to reconstruct the final output video. By doing so, it improves video compression efficiency while reducing the overall encoding complexity.
