Abstract
The detailed description presents innovations in performing motion estimation during digital video media encoding. In one example embodiment, motion estimation is performed using a lower-complexity sub-pixel interpolation filter configured to compute sub-pixel values for two or more candidate prediction regions at a sub-pixel offset, the two or more candidate prediction regions being located in one or more reference frames. For a selected one of the candidate prediction regions at the sub-pixel offset, motion compensation is performed using a higher-complexity sub-pixel interpolation filter.
