motion compensation and prediction Last modified: Monday, March 12, 2007
In video editing motion compensation provides a prediction for the macroblock. When prediction is applied, the DCT is applied to conform to the prediction errors instead of to image samples. Good motion compensation prediction will result in a lower bit rate and still maintain decent quality. Also called motion compensated prediction.

Motion Estimation Tutorial This page is intended to give the reader a basic understanding of what motion estimation is and how it fits into video compression as a whole. Motion Vector Applications We use these vectors creatively to detect and track motion and to find an alternative to traditional video decoding using phase shifting. motion-compensated coding (PDF) Prediction formulas and examples. Perceptual Coding: How Mp3 Compression Works The requirement that encoded video and audio must be retrievable from a medium delivering only 1.5 million bits per second dictated that one of the principal concerns of this document was data compression, since the transmission of uncompressed audio and video streams would require many more bits per second.
