MagicYUV – Lossless video codec
www.magicyuv.comMathematically lossless. Unlike visually lossless codecs, MagicYUV is mathematically lossless, meaning that the decompressed output is bit-by-bit identical to the original input. This means there is no generation loss. You can re-compress the same clip over and over as many times as you want without quality degradation.
