ZPEG is a motion video technology that applies a human visual acuity model to a decorrelated transform-domain space, thereby optimally reducing the redundancies in motion video by removing the subjectively imperceptible. This technology is applicable to a wide range of video processing problems such as video optimization, real-time motion video compression, subjective quality monitoring, and format conversion.

The ZPEG company produces modified versions of x264, x265, AV1, and FFmpeg under the name ZPEG Engine (see § Video optimization).
