Motion Estimation Like in Intra Prediction, when doing block-matching Motion Estimation a frame is split into blocks (typically 16x16, 8x8 and subdivisions like 16x8, 8x16, 8x4, 4x8, 4x4) Original Block match Motion Vector Field Current (P) frame Reference (I, previous) frame 53 PRESENTED BY
Motion Estimation Motion vectors field (MVF) quality can be represented by the amount of information in the residual (the less – the better) Original frame Residual Original-Compensated Compensated from reference (notice blocking) 54 Residual Original-Reference PRESENTED BY
