Abstract
Techniques for implementing adaptive interpolation filter search in video encoding are disclosed. Conventional interpolation filter searching is simplified to implement adaptive interpolation filter search by selecting one or more first filter types to determine one or more initial interpolation costs. After identifying an MV that produces a target interpolation error for one of the one or more first filter types, one or more secondary interpolation costs are calculated for one or more additional filter types based on the identified MV, and one of the one or more first filter type and one or more additional filter types that results in minimal interpolation error is selected as the interpolation filter type.
