  1. Motion compensation is an algorithmic technique used to predict a frame in a video, given the previous and/or future frames by accounting for motion of the camera and/or objects in the video. It is employed in the encoding of video data for video compression, for example in the generation of MPEG-2 files.

    What is global motion compensation (GMC)?Global motion compensation (GMC) is a motion compensation technique used in video compression to reduce the bitrate required to encode video. It is most commonly used in MPEG-4 ASP, such as with the DivX and Xvid codecs . Global motion compensation describes the motion in a scene based on a single affine transform instruction.

    What are the advantages of motion compensation in video compression?When images can be accurately synthesized from previously transmitted/stored images, the compression efficiency can be improved. Motion compensation is one of the two key video compression techniques used in video coding standards, along with the discrete cosine transform (DCT).

    Unter dem Oberbegriff Motion Compensation (dt. etwa: „Bewegungsausgleich“) oder Motion Prediction (deutsch: „Bewegungsvorhersage“) wird eine Reihe von Algorithmen zusammengefasst, die hauptsächlich bei der Videokompression eingesetzt werden. Die temporären Relationen zwischen benachbarten Einzelbildern ("frames") werden ausgenutzt, um die Gesamtmenge der zu kom…
